(47671) JUU Dedicated to the memory of Professor Samuel Wilson Parr friend and consultant and leader in chemical researches on Illinois coals Preface For nearly thirty years the State Geological Survey has been investigating the chemical character of Illinois coal. In so doing there has been in mind the eventual standardization of the product of our coal mines, providing a basis for discriminating selection by the consumer and accurate representation by the vendor. This is an end that could not have been attained at once because of the necessity for perfecting and standardizing sampling and analytical procedure, for developing a satisfactory basis for comparison and evaluation, and for collecting samples from a sufficiently large number of mines through a period of years to justify confidence in the conclusions drawn. From the time of the organization of the Survey until his death in 1931 the late Professor S. W. Parr of the University of Illinois either assisted in the planning and execution of the chemical studies in coal carried on by the Survey or was in friendly touch with the work that was being carried on. He searched diligently and we believe successfully for a basis of classification and selection that permits the accurate comparison of the quality of Illinois coals with one another and with competitive fuels. He did much to perfect the methods of sampling, and to improve and standardize analytical procedure. Professor Parr's particular contribution to coal classification was the de- velopment of a relatively simple method of expressing the heat value of the pure, that is the mineral-matter-free, coal substance. This theoretically pure coal he believed was essentially uniform in character for each individual bed over con- siderable areas, where geological conditions are essentially uniform as in most of the Illinois coal basin. Local variations in the coal as produced are, if this theory is correct, due to variations in the quantity and character of the impurities. Systematic sampling by the Survey of 100 mines in the State in 1912 and the careful analysis of the several hundred samples under Professor Parr's direction gave definite support to the theory of the uniformity of the essential coal material over large areas such as counties. Since that time additional information has sub- stantiated the validity of this early generalization. The mineral-matter-free, or what he called the "unit coal", values were like- wise regarded by Professor Parr as the basis for designating the rank classification of a coal. This method has been employed by the Survey for several years, and it is of interest to note that tentative specifications for the classification of coal by rank, recently announced by the American Society for Testing Materials and printed in Chapter II of this bulletin, are in close accordance with it. [51 It seems particularly appropriate, therefore, that the first attempt at applica- tion should be made in Illinois coals, inasmuch as the proposals are in line with practice that has long been in use by this Survey. County and district rank aver- ages have been published in our bulletins since 1914. The only important dif- ference between averages presented in the present bulletin and those previously presented is the use of moist rather than dry mineral-matter-free values, this being the basis preferred by the Coal Classification Committee. Since the publication of the last compilation of Illinois coal analyses in 1927 numerous mines have been sampled so that many more mining areas are now represented in our analytical files. Furthermore, the Coal Classification Com- mittee has indicated the desirability of eliminating from the compilations analyses made before 1912. A revision of the published compilations is therefore desirable to exclude analyses of doubtful accuracy and to include new analyses. Among the analyses and other experimental data presented will be found much information supplied by the United States Bureau of Mines. To this bureau the State Geological Survey is indebted for its vast amount of assistance in analytical work and for helpful criticism. Many of the analytical results contained in this bulletin were made for us under the supervision of Professor J. M. Lindgren in the Chemical Testing Laboratory of the University of Illinois, for which we make grateful acknowl- edgment. None of the work of determining the analytical character of Illinois coals would have been possible without the continuous hearty, confident support of the host of friends of the Survey through these many years among the producers and miners of coal. Cooperation in the task of collecting samples was invariable. It is impossible to detail the list of those in the coal mining industry who have helped in the accumulation of these data. Our thanks is likewise given to the American Society of Testing Materials for their courtesy in extending the privilege of publishing the tentative specifica- tions for the classification of coal by rank and grade found in Chapter II. The bulletin presents a compilation of analytical data in regard to Illinois coal so interpreted that it is believed even the small user of coal with sufficient interest in the matter of the discriminating selection of coal to investigate its possibilities can find herein the means for making such selection. The Survey is ready at all times to answer inquiries in regard to the coals of the State and to advise with regard to the application of the criteria recommended for use. M. M. Leighton, Chief.

Cady CHAPTER I INTRODUCTION, SUMMARY, AND ACKNOWLEDGMENTS This report has for its primary purpose the presentation of a compilation of available analyses of face samples of Illinois coal made by the State and Government laboratories between January, 1912, and October, 1934. The secondary purpose of the report is the application to Illinois coals of the system of rank and grade classification of coals recently announced by the American Society for Testing Materials and the explanation of a method for a discrimi- nating selection of these coals based upon the proposed system of classification. The analytical data presented indicate the nature of the coal as it exists in the bed, and the value of the data is primarily its usefulness in indicating the nature of the pure coal material — that is, the mineral-matter-free coal — which it is believed has an essentially uniform character for considerable areas within each bed. It is not desirable to use analyses of face samples as representative of coal as mined and prepared for shipment. They may be used, however, to indi- cate the character of the pure coal material, as the pure coal is probably not appreciably modified by the mining and preparation process. The use of ash and sulfur values given in this report as an expression of the ash and sulfur content of the coal as loaded at the mine is particularly undesir- able ; only analyses of tipple or car samples can supply such information. For some years a committee sponsored by the American Society for Testing Materials and working under the auspices of the American Standards Association, has been investigating North American coals for the purpose of recommending specifications for a practical and scientifically correct system of coal classification. Acceptance of proposed tentative specifications covering the classification of coal by rank and grade was finally announced by the American Society for Testing [11] 12 INTRODUCTION Materials in March, 1934 1 , and details of the specifications were presented in the following April 2 , followed by publication by the Society in September 3 . Plan of the report. — The general plan of the report following the intro- ductory chapter consists, first, of a presentation in full of the A.S.T.M. speci- fications for the classification by rank and grade. This is followed by a discussion of the general problem of coal classification and the nature of rank and grade. The specifications are then applied to Illinois coal and the application of the proposed scheme of classification to the problem of selection of Illinois coal by the user of small quantities of coal is explained. The discussion involves con- sideration of the distribution of variations in ash and sulfur in Illinois coals, the nature of variations in the softening temperature of coal ash, and in the agglutinating or coking strength of the coal. A general summary is given of the correlation, stratigraphic position, and distribution of the commercially important coal beds. The final chapter of the report discusses the nature of the analyti- cal data given in the tables in the appendix and elsewhere in the report. The analytical tables in the appendix consist of proximate analyses of individual samples, with a few ultimate analyses of individual samples in a separate table, mine and county average proximate and ultimate analyses, and a table showing ash softening temperatures of a large number of Illinois coals. In the text are tables giving the county average ash values for face samples for each county and agglutinating and slacking indices for various coals. Graphical methods of de- termining the as received heat value and certain other analytical values from mineral-matter-free values, and for comparison of the price of coals and of coal, oil, and gas are presented in Appendix II. Summary of method of coal selection. — The plan that is recommended for the selection of Illinois coal is based upon the well established fact of the uniformity of rank of the individual beds of Illinois coal over fairly large areas, commonly as large as a county. The rank of a coal, as is explained, is indicated by the heat value of the moist, mineral-matter-free coal. It is therefore proposed to designate the B.t.u. value of such coal, expressed to the nearest hundred units, the rank index, this being a value of sufficient precision for most purposes of comparison. The rank index of each coal bed and for many mines is given in the tables accompanying the report as are also the county average indices. The character of the coal produced at the individual mine in a county expressed in terms of its "as received" heat value can be readily ascertained from the rank index if the amount of mineral matter present in the coal is known. The "as received" heat value thus or otherwise determined is called in this report the 1 Bulletin American Society for Testing Materials, March, 1934, page 9. 2 Fieldner, A.

A simple method for obtaining a value for mineral matter from the ash and sulfur values makes the derivation of the heat index from the rank index an easy multiplication. Thus, with the standard rank index for any coal available it is possible for the purchase and sale of coal to take place on the basis of amount of heat purchased for each unit of cost, provided specifications applying to a particular coal include accurate statements of its ash and sulfur content. Analytical data. — The chemical analyses presented in the appendix and used as a basis for the discussion of the classification and selection of Illinois coals consist of a new compilation of all analyses of standard face samples of Illinois coal made during and since 1912 by the University of Illinois, the U. S. Bureau of Mines, and the Analytical Division of the State Geological Survey (since 1931), the character of which is explained more fully in the final chapter. This compilation supersedes that appearing in Illinois State Geological Survey's Cooperative Mining Series Bulletin 27 (originally desig- nated as an extract), entitled "Analyses of Illinois Coals", compiled by G. W. Hawley, published in 1923. The compilation of these data has been carried on interruptedly through a number of years. A preliminary task consisted in recalculating all analyses made before 1928, particularly the unit coal values. In 1929 the analyses avail- able up to that date had been tabulated and mine and county averages had been determined, the latter values appearing in Bulletin 56, "Illinois Coal", by A. Bement (1929). The second edition of this bulletin, published in 1932, carried a revised list of county averages based upon a slightly enlarged and an otherwise somewhat modified list of analyses. Since 1931 a fairly large number of analyses have been made so that several counties and seams are better represented than formerly in the analytical files of the State Geological Survey. The fact that during the meetings of the Coal Classification Committee doubt was thrown on the comparative value of analyses made before 191 2, 4 made it seem best to omit such analyses. Accordingly for the present report it was necessary to revise earlier lists, eliminating analyses made before 1912 and adding new analyses made since 1931 and to calculate new mine and county averages (Appendix). Furthermore, with the adoption of the moist, mineral matter-free values as the basis of rank classification, it became necessary to provide such values, at least for mine and county averages. The present list also contains unit coal (dry, mineral-matter-free), volatile, and fixed carbon values not presented in earlier compilations.

It is a pleasure to refer particularly to Mr. John Hughes 4 The date stated in the A.S.T.M. specification is 1913 (p. 21), but the methods used in 1012 in obtaining the analyses included herein were essentially those adopted by the American So- ciety for Testing Materials in 1913. 14 INTRODUCTION who assisted in the preliminary compilations, to Messrs. L. C. McCabe, Clayton G. Ball, E. T. Benson, and W. S. McCabe of the regular staff, and to Messrs. John F. West and W. A. Blomstran, temporary employees during the C. W. A. period. To Dr. M. M. Leighton, Dr. F. H. Reed, Dr. Gilbert Thiessen, and Dr. O. W. Rees of the Survey staff, and Professor D. R. Mitchell of the Depart- ment of Mining and Metallurgical Engineering of the University of Illinois, the author is indebted for helpful criticisms and suggestions. The writer wishes to express his personal appreciation of and to acknowledge the indebtedness of the Survey for the helpful cooperation of Dr. A. C. Fieldner, Mr. W. A. Selvig, and Mr. H. M. Cooper of the United States Bureau of Mines in arranging for and carrying through many proximate and ultimate analyses of coal samples supplied by the Survey, for furnishing analytical data from the files of the Bureau, in supplying agglutinating and slacking indices for a considerable number of Illinois coals, and for running occasional check analyses as an assistance in standardizing the operations of local laboratories. The bulletin contains many hundreds of analyses representing mine samples collected in nearly 300 mines in the State. This has required the services of many sampling parties and the helpful cooperation of the mine managment of the numerous mines. The analytical work has been carried on by chemists in three laboratories, that of the Bureau of Mines for the last several years under the direction of Mr. H. M. Cooper, that of the University of Illinois under the direction of Mr. J. M. Lindgren, and that of the State Geological Survey under the direction of Dr. O. W. Rees, by Messrs. John W. Robinson, Jr., Carl Westerberg, C. E. Imhoff, L. D. McVicker, G. C. Finger, and W. F. Bradley. The author wishes to make appreciative acknowledgment in the name of the Survey of the cooperation and assistance of all those who have helped to make possible the existence and compilation of these data. CHAPTER II TENTATIVE SPECIFICATIONS FOR RANK AND GRADE CLASSIFICATION BY THE AMERICAN SOCIETY FOR TESTING MATERIALS For the convenience of the reader and as a basis for the discussion that follows, the complete text of the tentative specifications for classification of coal by rank and grade is published herewith through the courtesy of the Ameri- can Society for Testing Materials in whose publications the specifications have previously been published. The specifications for classification by rank have the A.S.T.M. designation D 388-34T, and the specification for classification by grade the designation D 389-34T. In both instances the standards are desig- nated tentative and hence are subject to annual revision. Both specifications were issued in 1934. A single revision, but not one affecting the classification of Illinois coals, is in prospect for 1935. This will be noted at the proper place in the text. TENTATIVE SPECIFICATIONS FOR CLASSIFICATION OF COALS BY RANK 1 Scope 1. These specifications cover the classification of coals by rank, that is, according to their degree of metamorphism, or progressive alteration, in the natural series from lignite to anthracite. Basis of Classification 2. The basic scheme of classification is according to fixed carbon and calorific value (expressed in B.t.u.) calculated to the mineral-matter-free basis. The higher-rank coals are classified according to fixed carbon on the dry basis ; and the lower-rank coals according to B.t.u. on the moist basis. Agglutinating and slacking indices are used to differentiate between certain adjacent groups. Classification by Rank Classification by Rank 3. (a) Fixed Carbon and B.t.u. — Coals shall be classified by rank in accordance with Table 1. Coals having calorific values of 14,000 B.t.u. or more on the moist, mineral-matter-free basis, and coals having fixed carbon of 69 per cent or more on the dry, mineral-matter-free basis, shall be classified accord- 1 Under the standardization procedure of the Society, these specifications are under the jurisdiction of the Sectional Committee on Classification of Coals functioning under the procedure of the American Standards Association with the American Society for Testing Materials as sponsor.

TENTATIVE SPECIFICATIONS ing to fixed carbon on the dry mineral-matter-free basis; coals having calorific values less than 14,000 B.t.u. on the moist, mineral-matter-free basis shall be classified according to B.t.u. on the moist, mineral-matter-free basis, provided the fixed carbon on the dry, mineral-matter-free basis is less than 69 per cent. (b) Weathering Index. — Coals showing average weathering indices of less than 5 per cent shall be considered non-weathering, coals showing average weathering indices of 5 per cent or more shall be considered weathering from the standpoint of classification. (c) Agglutinating Index. — Coals having average agglutinating indices of 500 g. or more at a ratio of 15 parts sand to 1 part coal shall be considered agglutinating from the standpoint of classification.

A sharp point of any kind and a straight edge eight inches long are all that is nec- essary to use the charts. Chart I. — Coal Classification Nomograph The first chart includes the entire range of coal substances from peat to anthracite. Given "as received" or "moisture-free" forms of the proximate analysis, it is possible to determine quickly and easily from this chart the dry, mineral-matter-free (unit coal) B.t.u. or volatile matter values or the moist, mineral-matter-free values from the "as received" form of analysis. To determine mineral-matter-free values. — The heat value of a pound of the hypothetical dry mineral-matter-free coal (unit coal) is derived from the "as received" proximate analysis by the following formula: (1) Dry, mineral-matter-free (unit coal) B.t.u. = Determined B.t.u. — 5000 X Sulfur 1.00 — (Moisture + 1.08 X Ash + 0.55 X Sulfur) Or from the "dry" form of analysis by the formula: (2) Dry, mineral-matter-free (unit coal) B.t.u. = Dry B.t.u. — 5000 X Sulfur 1.00 — (1.08 X Ash + 0.55 X Sulfur) The heat value of a pound of the hypothetical moist, mineral-matter-free coal is de- rived from the "as received" form of the proximate analysis by the following formula: (3) Moist, mineral-matter-free B.t.u. = Determined B.t.u. — 5000 X Sulfur 1.00 — (1.08 X Ash + 0.55 X Sulfur) These formulae are quickly and easily solved by the use of the nomograph Chart I where approximate results are sufficient. The procedure is simple, the scales being used in numbered order, first Roman numerals and then Arabic, thus (letters refer to operations as indicated in key on chart) : Associate, Department General Engineering Drawing, University of Illinois. 2 These plates are reproductions of larger more convenient charts (12" x 13") available from the State Geological Survey at 15 cents each. 3 Parr, S.

For formulae No. 2 and No. 3 the moisture value on scale II is taken at 0. (b) Place straight edge from intersection point on scale III to point on scale IV (sulfur) and check intersection with scale V. Operations (a) and (b) solve the denominator portion of the formula (1.00 — (Moisture + 1.08 Ash4-0.55 Sulfur). (c) Place straight edge from point on scale 1 (B.t.u.) to point on scale 2 (sulfur) and check intersection with scale 3. (B.t.u. — 5000 Sulfur). (d) Place straight edge from intersection on scale V to intersection on scale 3 and note intersection on scale X, which gives the mineral-matter-free B.t.u. value, moist or dry as the case may be. This step divides the numerator by the denominator. To determine the dry mineral-matter-free (unit coal) and moist mineral- matter-free Volatile Matter. — The formula used in determining dry, mineral-matter- free (unit coal) volatile matter from the "as received" analysis is as follows: (4) Dry, mineral-matter-free (unit coal) volatile matter = Volatile Matter — (0.08 Ash + 0.4 Sulfur) 1.00 — (Moisture + 1.08 Ash + 0.55 Sulfur) The determination of the dry, mineral-matter-free (unit coal) volatile matter from the moisture-free or "dry" form of analyses is as follows: (5) Dry, mineral-matter-free (unit coal) volatile matter = Volatile Matter — (0.08 Ash + 0.4 Sulfur) 1.00— (1.08 + 0.55 Sulfur) The formula used in determining the moist, mineral-matter-free volatile matter from the "as received" form of analysis is No. 5, using "as received" values instead of "dry" values. Moisture is omitted. With the nomograph the procedure is as follows (letters refer to operations as indi- cated in key on chart) : (a) and (b) as in determining unit B.t.u. (e) Lay straight edge from point on scale A (volatile matter) to point on scale B (ash) and note intersection with scale C (Volatile Matter — 0.08 Ash) (f) Lay straight edge from point on scale C to point on scale D (sulfur) and note intersection with scale E (Volatile Matter — 0.08 Ash + 0.4 Sulfur) (g) Lay straight edge from intersection on scale E to intersection on scale V and note intersection with scale Y, which gives the mineral-matter-free volatile matter, dry or moist, as the case may be. This step divides the numerator by the denominator. It will be noted that the denominators of the equations for mineral-matter-free B.t.u. and mineral-matter-free volatile matter are the same so that steps (a) and (b) need be performed only once for both determinations. To determine "as received" B.t.u. and volatile matter values from mineral- matter-free values. — The procedure for the determination of the "as received" B.t.u. value from the mineral-matter-free heat values with the amount of ash, sulfur, and moisture known is as follows (letters refer to operations as indicated in key on chart) : For "as received" B.t.u. value: (a) and (b) as in the two procedures described above. (d) Place straight edge from determined point on scale V across mineral-matter-free B.t.u. value on scale X and note intersection with scale 3. (c) Place straight edge from intersection point on scale 3 across value on scale 2 and note intersection with scale 1, which gives the "as received" B.t.u. value and solves the following equation: 348 COAL CLASSIFICATION As received B.t.u. value = Mineral-matter-free B.t.u. X (1.00 — [Moisture 4- 1.08 X Ash 4- 0.55 X Sulfur]) + 5000 X Sulfur If the moist, mineral-matter-free value is used, moisture is regarded as (scale II) in manipulating the chart. If sulfur-free "Heat Index" is desired, the sulfur value (scale 2) in operation (c) is read at zero. This gives the "as received" heat value without the heat of the sulfur. If the "as received" volatile content is desired, proceed as follows: (a) and (b) as previously described. (g) Place straight edge from intersection point on scale V across known point on scale Y (mineral-matter-free volatile matter) and note intersection with scale E. (f) Place straight edge from intersection point on scale E to point on scale D (sulfur) and note intersection with scale C. (e) Place straight edge from intersection point on scale C to point on scale B (ash) and note intersection with scale A, which gives the "as received" volatile matter and completes the solution of the following equation: "As received" Volatile Matter = Mineral-matter-free Volatile Matter X (1.00 — [Moisture + 1.08 X Ash 4- 0.55 X Sulfur] 4- [0.08 X Ash + 0.4 X Sulfur]) Determinations derived from the moist, mineral-matter-free volatile matter value regard the moisture value as (scale II). For greater accuracy in determination of mineral-matter-free values from "as re- ceived" or "dry" values, or determination of "as received" or "dry" values from mineral- matter-free values Chart II is recommended, particularly for the high volatile groups of coals, such as are mined in Illinois. 350 COAL CLASSIFICATION Illinois State Geological Survey Bulletin 62, Plate II B.TU. r HEAT INDEX /9 h PER CENT PER CENT EAT INDEX SULPHUR MOISTURE NOMOGRAPH FOR COMPARISON By ALBERT JORGC DEPARTMEN GENERAL ENCINEER.NO BASED ON THE PAPR- .NIT BTU CIVEN IN uf DIS ENGINEERING t«PEi -USE THIS SCALE WITH 3 (PRICES 5 00 TO 20.00) COMPARISON OF COAL PRICE AND SPECIFICATION 351 Chart II. — Nomograph for Coal Comparison Chart II, which may be put to a number of uses, is designed primarily to be used with mineral-matter-free values, either moist or dry, as a basis of comparison of the economy of different coals. Comparison of heat value. — Chart II is used like Chart I in determining calorific value on any basis from that on any other basis. The scale of this chart is larger than that of Chart I as it represents a smaller range of coals and therefore permits greater accuracy in the determination of values. The method of use is similar to that employed in using Chart I. The procedure is as follows if determination of "as received" B.t.u. value from the mineral-matter-free value is desired (letters refer to operations as indicated in key on chart) : (A) Place a straight edge across scales 1 and 2 and note its intersection with scale 3. (In case moist, mineral-matter-free B.t.u. value is the original calorific value used, the moisture value is regarded as zero on scale 1). Ignore reading on scale 3. (B) Across scales 4 and 3 note intersection with scale 5. Ignore reading on scale 5. (C) Across scales 5 and 6 note intersection with scale 7. (D) Across scales 7 and 8 note intersection with scale 9, which gives the "as re- ceived" B.t.u. (The sulfur-free "Heat Index" ["as received" B.t.u. minus the heat of the sulfur] is determined by regarding sulfur as zero). The "dry" ("moisture-free") value can be determined only from the dry, mineral- matter-free (unit coal) value and "dry" ash and sulfur values must be used, the moisture scale (1) being read at zero. The chart is limited to coals within certain ranges of mineral-matter-free values, but scale 9, being uniform can readily be extended at either end. Comparison of prices and costs. — Chart II can also be used for making price com- parisons directly. This can be done on the "as received" basis, "dry" basis, or mineral- matter-free basis (moist or dry), by reference to a standard scale showing the cost of one million B.t.u., or showing the number of B.t.u. per 1 cent of cost. Knowing the num- ber of B.t.u. procurable for 1 cent, the relative value of the coal expressed in price per ton may be calculated, or it may be determined mechanically by the use of Chart II. For example, if it is desired to know the relative value of a coal priced at $5.00 and carrying 12,500 B.t.u. per pound as compared with another priced at $5.50 and carrying 12,800 B.t.u., the answer is obtained as follows (letters refer to operations as indicated in key on chart) : (Ei) A straight edge placed from 12,500 (scale 9) to $5.00 (scale 5) intersects scale 10 at the number of B.t.u. purchasable for 1 cent. The cost of one million B.t.u. at the price per ton stipulated — in this instance, 50,000 B.t.u. for 1 cent — is 20 cents. (E 2 ) Similarly a straight edge from 12,800 (scale 9) to $5.50 (scale 3) intersects scale 11 at 46,500 B.t.u. for 1 cent, which is 21 V2 cents for one million B.t.u. (E 3 ) A straight edge from 12,800 through the point on scale 11 representing 50,000 B.t.u. for one cent will indicate on scale 3 that the higher B.t.u. coal should be priced at $5.12 rather than $5.50 to be equal in value to the $5.00 coal. In comparing the value of coal for which standard moist, mineral-matter-free (rank index) values are given the only other specific information necessary is their ash and sulfur content, since these provide the means for determining the "as received" B.t.u. value as explained in the preceding section entitled "Comparison of heat values". The mineral- matter factor necessary for the determination of the "as received" value from the min- eral-matter-free value is the point on scale 5 determined by operation 2 in that section. 352 Illinois State Geological Survey Bulletin 62, Plate III - 8 ■ 3 NOMOGRAPH FOR COMPARING THE ECONOMY OF COAL, OIL, AND GAS AS FUELS By albert jobcensen DEPARTMENT or Engineering drawing *SlTr OF ILLINOIS 5 o r i OOS,O.SO— IO.OC LINES AMB SOLVE THE FIRST THREE EQUATIONS GIVEN BELOW ■ OF THE VARIABLES IN ANV ONE OF THE EQUATIONS MAYBE OB- THE OTHERS IN THE SAME EQUATION COS T OF ■ 1,000,000 NE .000; PB CE PER TON GROSS B.T.U PE R LB A EFFICIENCY X 200 J .

The diagram provides no means of determining the efficiency of the fuels, but with assumed or known efficiencies the cost of any three of the fuels of known calorific value may be calculated. The chart may be used for two purposes: (1) From it may be determined the cost of a million B.t.u. for coal, oil and gas, if the prices of their B.t.u. and the efficiency of the furnace or boiler in which they are used are known. (2) From it may be determined the price that should be paid for one fuel to result in the same cost per million B.t.u. as obtained from another fuel of known price. Illustration of use. — Suppose the B.t.u. values of a coal, an oil, and a gas, the heat efficiency of each, and the price per unit of each are known, and it is desired to determine the cost of one million B.t.u. for each fuel, and the price that would have to be paid for the oil and gas to obtain the same economy as is obtained from the coal, the data for the estimate being as follows: Coal: B.t.u. value 15,000 per lb. Efficiency 90 per cent Price $8.60 per ton Oil: B.t.u. value Efficiency Gravity Price B.t.u. value Efficiency Price 19,000 per lb. 80 per cent 80 per cent 53° Baume (Sp. Gr. 0.765) ,00 per bbl. $2.00 per 1,100 per 1000 cu. ft. 73 per cent $0.50 per 1000 cu. ft. Coal (1A) A straight edge is placed on the diagram crossing scale 1 (gross value of fuel) at 15,000 B.t.u., and scale 2 (per cent efficiency) at 90 per cent. Note intersection on scale 3 (net B.t.u. value). (IB) From this point (on scale 3) extend straight edge to point indi- cating $8.60 on scale 4 (price per unit in dollars), and read on scale 5 the cost of one million B.t.u. in dollars, which in this instance is $0,319. Oil (2A) A straight edge is placed on the diagram crossing scale 1 at 19,000 and scale 2 at 80 per cent, and the intersection with scale 3 is noted. (2C) To determine the price of oil in terms of pounds rather than gallons place the straight edge to intersect scale 7 (price of oil) at point indicating price $2.00 and scale 6 (density of oil) at 53° Baume and note intersection with scale 4. (2B) A straight edge intersecting scales 3 and 4 at the deter- mined points will intersect scale 5 and give the cost of one million B.t.u. in dollars, which in this instance is $0.49. 354 COAL CLASSIFICATION Gas (3A) A straight edge is placed on the diagram crossing scale 1 at 1,100 B.t.u. for gas and scale 2 at 73 per cent. It will intersect scale 3 at the point showing the net value of the fuel. (3B) From this point the straight edge is extended to pass through a point on scale 4 representing the price per thousand feet of gas. The cost of one million B.t.u. in dollars may then be read on scale 5, which in this case is $0.62. Upon scale 3 have been determined the net B.t.u. values of the three fuels, 13,500 for coal, 15,200 for oil and 800 for gas. On scale 5 the cost of one million B.t.u. of coal at $8.60 a ton (gross) is shown to be 0.319. By running lines from the net B.t.u. value of oil or gas through this point and extending them to scale 4 the prices that should be paid for oil or gas to result in the same cost for a million B.t.u. is found to be $0.00485 per pound for oil and $0.26 per 1000 cu. ft. of gas. To convert the price of oil per pound into price per gallon or barrel, let the straight edge cross scale 4 at 0.00485 and scale 6 at 53° Baume and the intersection with scale 7 gives the price per gallon or per barrel, which in this instance is $1.31.
