N presenting to the attention of Boiler Designers, Boiler Builders, and the Engineering Profession in general, designs of INTERNAL FURNACE TUBULAR BOILERS, it is the desire of THE CONTINENTAL IRON WORKS, to promote the adoption of boilers of this type, for stationary purposes. The introduction of Electric Light Plants, Central Power Stations, for either electric or cable traction, Water Works Pumping Stations, and for other purposes, where large boiler powers are necessary, makes it desirable to secure the most economical results in regard to their efficiency, and economy of space occupied by them. In Public Buildings, Office Buildings, Hotels, etc., the space devoted to the steam plant is usually in the cellar, and generally of quite limited dimensions, causing the choice of the proper type of boiler, which will best comply therewith, to become a question of prime importance. THE HORIZONTAL TUBULAR BOILER, with Furnace Grate beneath the shell, has heretofore been most in favor, and very generally adopted for Stationary Boiler service, particularly where ordinary steam pressures, not exceeding one hundred pounds per square inch, have been sufficient ; but the increasing demand for much higher steam pressures, has brought into vogue other types of Steam Generators, notably the various designs of Water Tube Boilers, all of which are subject to the same character of defects, as are incident to every type of boiler, which is set in surrounding walls of brick, between which walls, the furnace is contained. These defects, generally consisting of the cracking of the walls, due to unequal heating and cooling, and consequent expansion and contraction, permit very considerable loss of heat through the interstices, which, together with the radiation from the mass of brick work, becomes a serious detriment to effective Boiler duty. The volume of water contained in all Water Tube Boilers, is relatively small, and necessarily affords but a limited reservoir for the storage of heat, the effect of which, is frequent and rapid fluctuations in steam pressure, unless the "feeding" and the "firing" of the boiler are exceedingly regular. INTERNAL FURNACE BOILERS contain relatively greater volumes of water, which act as reservoirs of heat, to be used as occasion demands, and aids in keeping the steam at constantly uniform pressures, which is a feature of vital importance. In locations where " hard " or " contaminated " water must be used, accumulations of mud and scale adhere to the inside surface of the tubes and headers of Water Tube Boilers, which it is RET m practically impossible to remove, the effect of which is to shorten the life of such boilers, and eventually making them untrustworthy and probably dangerous. In boilers of the Internal Furnace type, it is practicable, by means of the Manhole and several Handholes, to remove all deposits and accumulations, and give the interior of the Boiler proper care. In marine practice, the " Scotch Boiler " has been found to fill all requirements in an eminent degree, and it is to a similar type of INTERNAL FURNACE BOILER, slightly modified in its back connections, without detriment to its characteristics, to which attention is requested. Referring to the drawings, it will be observed that the type of INTERNAL FURNACE BOILER presented, consists of a horizontal cylindrical shell, having an internal suspension, or corrugated Furnace, within the front portion of which, the fire grate is located, the other portion, or end of the furnace, terminating in a back connection, or combustion chamber, consisting of a "fire brick lined" metallic casing, forming in effect, an extension of the boiler shell. The products of combustion pass from this chamber, through the horizontal tubes, and are delivered into a sheet iron breeching, attached to the front head of the boiler. This breeching may be connected directly with a smoke stack, or in the case of a battery of boilers, it may be attached to an uptake leading to a common chimney. Several modifications of INTERNAL FURNACE TUBULAR BOILERS may be made. For example : Boilers may be arranged to contain two or more comparatively short furnaces, terminating in a common combustion chamber, from which, tubes lead directly to a smoke connection at the rear of the boiler, without returning forward over the furnaces, thus forming the well known " Locomotive " Type. Boilers of this latter type are used in several Gun Boats, and third-rate Cruisers of The United States Navy, also by numerous Water Works corporations, and are highly esteemed. INTERNAL FURNACE BOILERS are economical in first cost, because of being "self contained ; " that is, they are independent of masonry setting, cast iron fronts, buckstays, tie rods, etc., requiring but little foundation preparations, and are susceptible of being easily removed from one location to another with but little expense. They are economical in the consumption of coal, from the fact that the furnaces being surrounded by water, the heat of combustion is utilized to a greater extent than is practicable with boilers having external furnaces contained within brick wall settings. Morison Suspension Furnace. This type of furnace (designed and patented by Mr. Donald B. Morison, of West Hartlepool, England) is the result of a series of exhaustive experiments which were conducted at Leeds, England, under the auspices of Mr. Samson Fox, the original introducer and promoter of the world renowned FOX CORRUGATED FURNACE. So indispensable has the latter type of furnace become, that more of them are in constant use than the aggregate of all other types of horizontal cylindrical furnaces. The advent of the Fox invention, wonderfully advanced the standard of boiler design and construction, and early commanded the highest consideration of all Boiler Designers, Builders and Users, steadily maintaining its distinction until the appearance of the MORISON SUSPENSION FURNACE, which at once assumed equal rank. These two designs are still unrivalled notwithstanding the fact that, during the last decade, numerous attempts have been made to produce some type of Boiler Furnace, which would vie with, and share in their established reputation. The MORISON SUSPENSION FURNACE inherits, in pronounced development, all of the well known features, which have so firmly established the reputation of the FOX CORRUGATED FURNACE. The catenary form of curve in the MORISON SUSPENSION FURNACE, the distance between the centers of ridges of support, together with the general proportions as finally adopted, were experimentally ami practically determined, and have proved to offer the greatest resistance to distortion or collapse, presenting a heating surface, which offers the minimum facility for lodgment of scale, and maximum convenience for readily removing the same when formed. The MORISON SUSPENSION FURNACE is free from liability to crack and become distorted, accidents so incident to a type of cylindrical furnaces, which are reinforced with thick ribs rolled thereon ; also from the leakage, incident to all types of furnaces, which consist of sectional Hanged and riveted cylinders, with reinforcing rings interposed between the flanges. The freedom of the MORISON SUSPENSION FITRNACE from these adverse and destructive features, has caused its adoption in numerous instances, to replace derelict furnaces of other designs, which, because of the above described troublesome characteristics, have made their substitution a necessity. MORISON SUSPENSION FURNACES are made of the very best material, of specified chemical and physical characteristics, which, together with the first-class workmanship necessarily required for their production, insures perfection in the completed product. An important feature of commercial interest is the fact that either type of furnace, namely, MORISON SUSPENSION, or FOX CORRl T GATED, of equal dimensions and requirements, may be purchased at the same prices. The sole right to manufacture and sell the MORISON SUSPENSION FURNACE and the FOX CORRX T GATEI) FURNACE, within the United States and Canada, is the property of TFIE CONTINENTAL IRON WORKS of NEW YORK, BOROUGH OF BROOKLYN. 10 73 Z > c 73 Z > o m oo O o o z w o r o > -i m o O > M O S > 1 H z — .-< co Z 3" m S S CO H > 11 < Q N D u. o C U- C .2 c a 3 o o Of 33 0. o r a 3 O Of O 03 o z The Following Rule for Calculating the Thickness of Metal for Morison Suspension Furnaces, ■when the inside diameters and working pressures are known, is that adopted by the Hoard of U.

(BOROUGH OF BROOKLYN.^ 15 Kit RATING THE POWER OF BOILERS. The term Horse Power, as used in relation to steam boilers, is the capacity to evaporate 30 pounds of water per hour from a temperature of 100° Fahrenheit into steam at 70 pounds gauge pressure, or 341 pounds of water evaporated per hour, from a feed water temperature of 212° F. into steam at atmospheric pressure. This unit of power is that adopted by the American Society of .Mechanical Engineers and generally accepted as a standard. In many tests made upon boilers of the Internal Furnace Type they have evaporated 10 pounds of water per pound of coal burned per hour. In designing the Internal Furnace Boilers illustrated, an evaporation of 10 pounds of water per pound of coal, having 10$ ash, burned, and a consumption of 18 pounds of coal per square foot of grate per hour, have been used as a basis. With the above data a simple calculation shows that these boilers will produce 5 Boiler Horse Power per square foot of grate. The following table gives the general proportions and sizes upon which the various designs have been carried out. General Proportions of Internal Furnace Boilers Ranging from 75 to 300 H.

GENTLEMEN : — Referring to our conversation of a day or two since, in respect to the relative merits of internally fired boilers and those fired externally ; I have to say. For over two years, we have operated two internally fired boilers at our water purnping station in Virginia, with the most satisfactory results, having raised 500,000 gallons of water to an elevation of 185 ft., da}' after day, with a con- sumption of only 1500 to 1600 lbs. of coal. If we were again to construct our Plant, we cer- tainly should use internally fired boilers, believing them to be the most economical. In confirmation of the above opinion regarding boilers with internal furnaces, I have further to say, that at The Newport News Ship- building and Dry Dock Co. we have a battery of four Scotch boilers, serving our Plant, and we consider that we are getting most economical service. We prefer boilers of the internally fired type, believing that the heat in this way, is best utilized in the evaporation of water. The percentage of loss in radiation, being reduced to a minimum. Yours very truly, (Signed) C. B. ORCUTT, President of Newport News Light and Water Co., also of Newport News Shipbuilding and Dtv Dock Co.

Gentlemen: — Referring to the internally fired boilers that we are now using, I beg to say, that we put in the first pair in the year 1889, and were so well pleased with their performance that since that time in the course of alterations and repairs to our various plants we have introduced them and now have eleven in active service. I do not think they can be surpassed in either economy or efficiency, are set up or moved with ease, and not being encumbered with a mass of brick work can be at all times readily inspected and cared for when necessary. We have not as yet had occasion to spend a dollar on repairs on any one of them and we shall probably increase the number now in use in the near future. Yours truly, (Signed; W. H.

DAVIDSON, Manufacturer of Improved Steam Pumps and Hydraulic Machinery, Principal Office and Works: 43=53 Keap Street. Brooklyn, Sept. 26, 1895. The Continental Iron Works, Brooklyn (Greenpoint), N. Y. GENTLEMEN: Replying to your inquiry in reference to the efficiency of the ten internal furnace boilers recently furnished by me, in connection with my contract to install pumping engines at the " Milburn Station," of the Brook- lyn Water Works, I have respectfully to say. There are two batteries, consisting of five boilers each, and they have given the best satisfaction. Five of them have been in almost constant use for four years, the other five have been in use for about two years, and none of them have cost anything for repairs during these respective periods. So entirely satisfactory has been my experience with the type of boilers which I furnished and caused to be erected at the pumping station above alluded to, that I could not be induced (of my own volition) to use, or recommend to others, any type of boiler not possessing the character- istics of the internal furnace boilers at " Milburn Pump- ing Station," for this type completely dispenses with carefully prepared foundations and the ordinary sur- rounding walls of brick. The iron furnace front, the buckstays, tie-rods, etc., all of which are necessary to the setting of stationary boilers with external furnaces, and which are adjuncts constantly liable to become dis- arranged, thereby involving much inconvenience and loss, creating large expenses in frequent repairs. In this latter type of boiler the mass of brick work so closely surrounds the sides and top of the cylindrical portion as to preclude perfect inspection, and causing difficulty in the making of repairs. Whereas the Internal Furnace type of boiler can be critically examined and repaired (if occasion requires) with the utmost facility. Again, referring to the boilers and pumping engines at the "Milburn Pumping Station," I am pleased to say that while working under the very low head of 52 feet maximum, and delivering nearly 40,000,000 gallons of water, per day of twenty-four hours, the engines developed an economic duty of 92,000,000 pounds feet for each 100 pounds of coal consumed, evidencing an evaporation of at least ten pounds of water for every pound of coal sup- plied to the furnaces. A result, very much better than I have before known to be accomplished by the use of any other type of boiler, and I have had much experience, as there are over four hundred boilers in the United States, which I have built and placed in service. Very truly yours, (Signed) M. T.

Thomas, Secy. JOHN WANAMAKER, Mechanical Department. Philadelphia, October 15, 1895. The Continental Iron Works, Brooklyn, N. Y. GENTLEMEN : In reply to your verbal inquiry of our Mr. Hand in relation to the advantages of the internally fired type of boilers over those of the externally fired type, set in brick work, without going at any length into the subject, we beg to say that after ten years' experience in the building of internally fired boilers we have no hesita- tion in recommending them as the very best boilers for both power and industrial plants. The particular design of this type that we have adopted for stationary use is the furnace-flue tubular boiler, which is a modification of the Scotch and Lancashire boilers, combining the best features of these two types. The advantages of this type of boiler over those of the externally fired type are many and may be mentioned in the order of their importance : First : As to efficiency ; ignition and combustion of the fuel taking place in fur- naces and chambers surrounded by water the heat evolved is utilized in evaporating water, while in exter- nally fired boilers much of the heat is lost in radiation through the outside walls of the furnaces and setting. This in itself is an important item, and the efficiency of the two types is about in the proportion of 62^ and 65$ to 70$ and 75/r. Second : As regards space occupied ; with a given space, all conditions being the same, the internal furnace tubular boiler will have about 40$ additional capacity. This particularly recommends it for adoption in power plants where space is a great factor. The cost of maintenance is practically nothing, as there are no brick walls to repair, no brick furnaces to re-line, and the boiler itself is so constructed that it maybe thoroughly examined inside and out, so that a complete inspection can be made and its exact condition ascertained at any time. The boiler being self-contained is in a measure port- able and this feature permits of its being moved at very little cost to accommodate the growth and enlargement of power stations. These are a few of the many advantages which this type of boiler possesses, and we strongly urge its adoption in all modern steam plants. We enclose you a copy of a letter from Mr. Andrew Shearer, Mechanical Engineer for Mr. John Wanamaker, of this city, in reference to the subject, and trusting this information will answer your purpose, we are, Yours very truly, (Signed) I. P. Morris Co., Wm, P. Thomas, Secretary. Philadelphia, May 9, 1894. To whom it may concern : On account of the numerous inquiries as to the work- ings of the improved type of double internally fired boilers in use by us, generally termed marine boilers by those who have had them in use, we have thought it advis- able to prepare the following facts. In the spring of 1892 we had eleven boilers in use, four of them were water tube boilers. They had given us a great deal of trouble and were constantly out of repair. As a general thing it took the eleven boilers to supply us with enough steam to do our work. The four water tube boilers referred to were built under a guarantee to work up to 100 H. p. each. We took the four boilers out and introduced four boilers above referred to built by I. P. Morris Co., 8 ft. 6 in. in diameter, 26 ft. long. We had them in working order in the fall of 1892, since which time they have given us no trouble whatever. We have added considerably to the amount of our machinery since that time, in the shape of one new Eleva- tor, 1-800 Lt. Incandescent dynamo and 1-10 Lt. arc machine, and we consider, near as our record goes, we have burned 50 more arc lights daily since that time, and we find that with the four boilers and two return tubular boilers of 60 H. p. each, we can do all of our work with perfect ease, leaving our other five boilers laying idle. We are burning Buckwheat coal of a very poor grade, and our consumption of coal for the years 1S90, '91, '92, '93, is as follows : 1890 5399 Tons. 1S91 S^S^i Tons. 1892 4819 Tons. 1893 422oJ£ Tons. Considerable allowance should be made for the coal consumed during 1892, because during the change of boilers we reduced our number of lights and machinery to the lowest possible point. We are at present working these boilers in bank, but we have disconnected them and worked them singly. They give us the same satisfaction either singly or together. We should be glad to have any one inspect the boilers as they are now placed, and we know from experi- ence with a first class coal and a good draught they can be made to do more than is even claimed for them by their builders. Respectfully, (Signed) Andrew Shearer, Master Mechanic for John Wanamaker. PT7 32 TESTIMONIALS. WILLIAM B. POLLOCK & COMPANY, Steel and Iron Plate Work. Youngstown, Ohio, Nov. nth, 1897.

Gentlemen : — Replying to your favor of the 9th, beg to say that the Furnaces furnished us in April, 1896, and to which you particulary refer, are in use in this city, at the Youngstown City Water Works. We are glad to say that the reports from the City Water Works are very encourag- ing ; they simply say that the Boilers are most satisfactory. There have never been any repairs made nor, from present indications, are there likely to be for a number of years; they appear to be in as nice shape to-day as they were the first day they were filled with water for use. The reports have been confirmed by trustees and others connected with the Water Works at various times ; just the other day one of the trustees stated that they were the most satisfactory boilers he has ever had to look after. The trustee mentioned is a Master Mechanic in one of our largest foundry and machine shops and, therefore, we set a great deal of value on his statements. Yours truly, (Signed) William B.

Prevents the Destruction of Baffle Plates. HE MORISON PATENT FURNACE FRONT AND DOOR is intended to overcome some of the defects which are inherent in the present type of furnace doors iu use on marine and laud boilers. The primary object is to prevent the undue accumulation of fuel on the front end of the grate which causes overheating and ultimate destruction of the furnace door and its attachments, and in consequence of the freedom from obstruction in the front end of the furnace, much better facilities are afforded for properly stoking the fire. To accomplish this, a portion of the dead plate immediately inside of the furnace door is left out, so as to leave a recess. The door is provided with an inward extension, which, when the door is closed, fills the recess in the dead plate. This extension, also the vertical portion of the door, may be perforated and provided with a perforated baffle plate. THE FURNACE FRONT is made of a plate of pressed steel, worked to the shape indicated in the illustrations and protected from the fire by perforated cast iron liners. THE FURNACE DOOR is arranged to open upward and is so counterweighted as to remain open while the furnace is being stoked. This is a very important feature in a marine boiler, as it does away with catches or other devices for preventing the door from closing with the motion of the ship. ANOTHER VALUABLE FEATURE of the Morison Patent Furnace Door is, that in consequence of the fire beiug removed from the immediate front of the furnace, the fire room is much cooler, which allows the men to work with more comfort than when the ordinary form of door is used. THESE FRONTS and DOORS are made of several sizes to suit different size furnaces.
