Y.; Brooklyn, N. Y.; Toronto. Canada Dealers in Principal Cities and Towns in the United States and Canada t Representation in numerous foreign countries COMMERCIAL AND INDUSTRIAL STOKERS STANDARD HOPPER MODELS This series of stokers is the standard of value in equipment for automatically firing boilers ranging in size up to 350 hp. Available in a wide range of coal feeding'capacities, _ Commercial Installation--Hopper Model Hopper Model Iron Fireman in Operation in Horizontal Return Tubular Boiler STANDARD COAL-FLOW MODELS Commercial-Industrial Installation Coal-Flaw model that carries coal direct from main bin or bunker to fire A heavy duty stoker which combines Iron Fireman's well known firing efficiency with the automatic conveying of coal direct from bunker to fire. An integral coal con veying mechanism eliminates the labor and expense of manual coal handling. The IRON FIREMAN COMMERCIALINDUSTRIAL COAL-FLOW stoker fires boilers developing up to 350 horsepower. PNEUMATIC SPREADER STOKERS also available in Coal-Flow models. POWERAM STOKERS Combines ram-type coal distributor system in retort with free-running worm conveyor from coal supply, and has these advantages: Delivers the fuel to the fire bed in a loose, easily aerated condition; the reciprocating pusher blocks insure proper fuel distribution, and make possible the successful and efficient burning of many types of coal which otherwise are impractical to fire automatically with underfeed stokers. Designed for boilers developing up to 400 hp. 1174 Iron Fireman Manufacturing Co. Heating Systems Automatic PNEUMATIC SPREADER STOKERS As shown in the illustration above, the' IRON FIREMAN PNEUMATIC SPREADER STOKER meters steam size coal from hopper or main coal bunker to transfer housing, where coal is picked up by pneumatic conveyer and delivered to furnace. The conveyor nozzle accurately spreads the larger particles of coal over the entire grate in a shallow, uniform fuel bed. The preheated fines burn in sus pension, reducing the cinder carry-over and greatly improving the combustion efficiency and responsiveness, as compared with other stokers which do not preheat fuel. The conveying air provides the over fire air which is essential for efficient combustion. Entering at right angles to the flow of burning gases from the fuel bed, the con veying air produces maxi mum turbulence; another requisite of efficient and smokeless combustion. THE IRON FIRE MAN PNEUMATIC SPREADER STOKER was designed to burn effici ently such economical fuels as the lower rank bitumin ous, and sub-bituminous coals and also lignite. It provides reliability of opera tion, physical adaptability, ease of opera tion, and low maintenance which is not afforded by other types of automatic coal burning systems. Pneumatic Spreader stokers are particularly adaptable to operation at high ratings, and as a result are greatly stepping up steam output in many plants throughout the United States and Canada. IRON FIREMAN PNEU MATIC SPREADER STOKERS are made in both' hopper and Coal-Flow models; the latter carry coal direct from the bunker to the fire. Available in capaci ties up to 1000 hp per nozzle. Multiple units for larger boilers. INDUSTRIAL OIL BURNER Oil Volumeter accurately regulates oil regardless of its temperature or viscosity This industrial oil burner brings new precision and dependability to the firing of high viscosity oils. Accurate adjustment of the fuel feed rate, eliminating pulsating fires and difficult "cold boiler room" starting, is achieved by a principle of multiple-piston feeding. This positive feed control produces a steady flame even when burner is throttled down to low capacity. Any fuel oil, from the lightest to the heaviest, will operate without need for special adjustments. Models available for manual, semi-automatic, or fully auto matic operation. Control combinations can be provided to meet individual re quirements. Available in capacities from 8 to 125 gph., to develop up to 425 hp.
