ILLINOIS "■fe> Steel Power and Heating Boilers, Wfe/ |P Radiators, Tanks and jv" Garbage Burners CHICAGO NEW YORK ST. LOUIS KANSAS CITY CLASSICS 325 M Copyright, 1914 by Kewanee Boiler Company A REMARKABLE SAVING In an apartment building at the corner of West End Avenue and 71st Street, New York City, two number 117 Kewanee Smokeless Firebox Boilers are installed. To heat these buildings they use a daily average of \ l / 2 tons of Bituminous Coal costing $3.75 per ton. A coal cost of $5.62 daily. In another building of the same size owned by the same con- cern and erected by the same builders, under the supervision of the same engineers, another make of boiler is installed. To heat this building more than three tons of Anthracite Pea Coal, costing $4.50 per ton, are used daily. A daily coal cost of $13.50. The Kewanee Smokeless Firebox Boiler saves the owners $1,654.80 in an average heating season of 210 days. This remarkable saving is accomplished in two ways. PERMITS THE USE OF CHEAPER COAL The Kewanee Smokeless Firebox Boiler permits the use of cheaper coal — because it burns it without smoke. The other boiler, not built for burning Bituminous Coal smokelessly must use higher priced Anthracite. Government analysis of the Pennsylvania, xMaryland and West Virginia Bituminous Coals, which are sold in New York for an average price of $3.75 per ton, shows that this coal averages about 14,100 British Thermal Heat Units per pound: The cheapest anthracite coal that can be burned in the ordinary boiler, and comply with New York City's stringent smoke ordi- nance, is a pea size costing about $4.75 per ton. This grade of anthracite coal contains only about 12,000 heat units per pound. That means that the installation of a hand fired boiler, which will burn soft coal smokelessly, makes it possible to use a grade of coal costing about $3.75 per ton which contains 17% more heat than the anthracite pea that costs $4.75 per ton. It is also true that in some cases in New York City better grades of coal than anthracite pea are used, and the price of such better coal is sometimes as high as $6.50 per ton. Were buildings CUTTING COAL COSTS IN NEW YORK CITY using such fuel taken for the sake of comparison the showing would be even more in favor of the use of soft coal in a smokeless boiler. SMOKELESS BOILERS SHOW GREATER EFFICIENCY Smoke is visible proof of wasted fuel. So any boiler which is capable of burning a highly volatile soft coal without smoke is proving itself to be highly efficient — and very rigid tests have proven that a down draft hand fired boiler, such as the Kewanee Smokeless, will average 22% greater efficiency than the ordinary boiler. That means that a Kewanee Smokeless Firebox Boiler saves the owner fuel money in two ways. First, it permits him to burn cheaper coal — and second, it takes from this coal and uses for heat making purposes, on an average, 22% more of the heat in the fuel than is used by ordinary boilers. Here is another case of a great fuel saving : In an apartment house at 3 East 85th Street, New York City, a number 114 Kewanee Smokeless Firebox Boiler, carrying 6,100 square feet of radiation and supplying in addition the hot water used, burns an average of 4/10ths tons of bituminous coal per day. This coal costs $3.75 per ton, which makes the daily coal cost about $1.50. In another apartment house, nearby, an ordinary straight draft boiler is used to heat 5,300 square feet of radiation, and burns dailv an average of one ton of prepared Anthracite costing $6.50. EXPERIENCE HAS SHOWN SAVINGS Summing up what experience in New York City has shown to be facts we find that Kewanee Smokeless Firebox Boilers using bituminous coal at $3.75 per ton will make the following savings as compared with ordinary boilers: A saving of 2S ( " ( , compared with the ordinary boiler using Buckwheat, steam grade at $3.75. A saving of 45% compared with the ordinary boiler using An- CUTTING COAL COSTS IN NEW YORK CITY thracite Pea: And a saving of 54 r ( compared with the ordinary boiler using prepared sizes of Anthracite at $b.50 per ton. REPEAT ORDERS PROVE EFFICIENCY That the Kewanee Smokeless Firebox Boilers are proving highly efficient is proven conclusively — not only by their installa- tion in some of the best buildings in New York City, as well as in all other parts of the country, but also by the repeat orders. For instance : The Fullerton Weaver Realty Co. of New York City in response to an inquiry from another building operator wrote him as follows: "In reply to your favor of the 14th in regard to Kewanee Smokeless Firebox Boilers, we beg to advise that we have not yet had sufficient opportunity to determine definitely the exact saving in fuel obtained through the use of these boilers, but we have demonstrated to our satisfaction that there is a considerable saving and the boilers have been so satisfactory that we have just ordered two more for our new building." The following photographs of New York City Buildings where Kewanee Firebox Boilers and Kewanee W ater Heating Garbage Burners are installed is further testimony of what the best known and most efficient builders think of Kewanee products.
