Specialties, Healing Combustion Specialties Corporation Walter S. Timmis, past president of the American Society op 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 COMiHSTO SYSTEM 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 reauired 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. alt . 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 hoi water or heating boilers or warm ah -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 baric styles--each style is capable of adjustment to meet 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 low pressure heating boilers.

Davis Regulator Company Manufacturers of Automatic Valve Specialties 407 MILWAUKEE AVENUE CHICAGO New York Office, 71 Fulton Street--Sales Representatives in Principal Cities Fig. Sgl Back Pressure Valve Fig. 305--The Davis Standard Regulator is constructed for automatic steam pressure reduction. It accom plishes its purpose in the most direct manner and with the least liability to go wrong. It has visible action-- you can see it work--you can test it by hand. Good for any service pressure. Fig. 321--To automatically regulate the pressure of exhaust steam is the purpose of the Davis Noiseless Back Pressure Valve. The globe pattern may be used either horizontally or vertically. The piston disc is semi-balanced which results in reducing the size of the counterweight necessary to maintain a given pressure. Fig. 311--This Regulator is for use on vapor, vacuum and low pressure heating systems, yavjng a diaphragm of large area and no stuffing box.-faisiyery sensitive. Control pressure is taken from the SgFvice pipe 5 to 10 feet ahead of the valve where an accurate average pressure may be had. Fig. 318--The Davis Float Valve ,will .automatically maintain a constant `water level in a tank or reservoir. A distinctive feature is its tight closing disc--it will not leak. Another feature is its loosely fitted piston--it will not stick. Frictionless operation insures accurate regulation. Send for general catalog Fig.SU Pressure Regulator--Diaphragm Type -i.
