Its products comprise all Special Modulation Valve devices and apparatus used in up-to-date vacuum and vapor Heat- B. b3 B. Multiflex Trap No. G ing Systems, Temperature Control arid Ventilating Systems. It is entirely practical for an engineer and architect to standardize with Bishop. & Babcock apparatus--every device for the entire system can be a B. & B. product. Bishop j& Babcock has been manufacturing heating, ventilating and temperature control apparatus for many years, its installations including many of the most prominent buildings in all parts of the country, Seamless one-piece Multiflex Metal Bellows are a fundamental part of Bishop & Babcock Heating Specialties and Temperature Regulation. In the manufacture of these vital parts for the construction of Ther mostatic Traps, Valves, and other devices Bishop & Babcock exercise the same care and rigid adherence to high standards that characterize all their products. Our Engineering Data Book, pocket edition, will be mailed upon request. Separate catalogues are issued on- Bishop & Babcock Temperature Control Systems and Massachusetts Fans, Blowers and Air Washers --copies of which will be furnished upon re- AU Metal Thermostat quest. 494 Single Width Squirrel Cage Fan Specialties, Heating Combustion Specialties Corporation Walter S. Timmis, past president of the American Society of Heating and Ventilating Engineers has written an extensive report on COMBUSTO Draft System from which the following paragraphs are quoted. (Complete re port will gladly be for warded on request.) Manufacturers of MSSTOI 250 West 54th Street, New York For Heating Plants Saves coal and labor, maintains even heat with less draft. For Power Plants Higher evaporation per pound of coal eliminates smoke Mr. Timmis states, "To secure the most eco nomical results in combustion for heating it is necessary to use the proper amount of air under the fuel bed for the distillation of the gases and the correct amount of air properly diffused, preferably heated and delivered over the fire bed in order to complete the combustion by burning the distilled gases-*--in brief--an efficient boiler is a gas producer having means for consuming gas produced." WHAT COMBUSTO IS To quote Mr. Timmis further. "Combusto is a system carefully studied, tested and developed for each individually different case and provides means for supplying the necessary diffused and heated air (oxygen) over the fire to properly com plete in the second stage the combustion begun in the fuel bed by distillation of gases." UNIQUE AND FUNDAMENTAL REQUIREMENT FOUND IN COMBUSTO - "Perhaps the most important feature of Com* busto is the resistance to the flow of air through the apparatus itself, which is made to equal, the resistance of the fuel bed, thus producing a balanced condition above and below and through the fuel bed--a fundamental requirement for correct and economical combustion which is ignored in regular furnace and boiler design. WHAT COMBUSTO DOES (See illustration of COMBUSTO equipped plant below.) "Combusto is of cast iron cellular structure, the air is heated on passing through this structure and is then discharged through a large number of small apertures over the fire bed. The amount of air thus admitted having been carefully computed for the required conditions, the result is practically perfect combustion, which to the user of Combusto results in-- Economy of fuel Fewer firings Complete combustion of fuel, hence--A finer ash and reduction of clinker Elimination of coal gases Means for producing a steady even heat." COAL WASTED (Left) Without Combusto, a checked fire produces no dependable results. The gases that distill from fuel bed are a total loss. Heat can be produced only by speeding up stack draft. This is wasteful and re quires frequent attention. COAL SAVED (Right) With Combusto, all gases are burned completely with Bunsen blue flame with stack draft continu ously checked to minimum. Hence, amount of gas made can be regulated to amount of heat needed by simple adjustment of the ash pit damper. SPECIFICATION: The following clause adopted since 1916 by one of the largest railways in the United States is suitable as a standard specifica tion in connection with low pressure hot water or' heating boilers or warm air plants.', "Equip all boilers (warm air furnaces) with Combusto of size recommended by Combustion Specialties Cor poration's engineers." STYLES: Combusto is manufactured in 28 basic styles--each style is capable of adjustment td ihe^h specified conditions. Suitable styles are manu factured for practically any type of heating-plant and for all sizes and grades of fuel. '. PRICES: Prices range from $25.00 on; small house-heating-plants to $200.00 on largest Tdw pressure heating boilers.
