IRON FIREMAN Automatic Coal Burners "Forced Underfiring" Principle --Iron Fireman "Forced Underfiring" is based on the scientific principle of feeding fuel to the fire from below, under forced draft. From the con veyor screw coal enters the firebox under the fire and is gradually forced up ward into the flame. As the coal ap proaches the fire, it is gradually heated. The volatile gases are distilled off in the presence of an excess of oxygen and are thoroughly ignited while passing through the incandescent fuel bed. This insures complete combustion. The ash is fused into clinkers which are easily removed. Advantages--Iron Fireman saves money and in creases heating plant efficiency in four major ways: (1) Cuts fuel costs; (2) Reduces labor costs; (3) Provides steady, Typical Installation Down even heat or Draft Firebox Boiler power; (4) Elimi nates the smoke nuisance. Installation and Sizes--Iron Fireman is made in a range of hopper and bin-feed sizes for commercial heating and power boilers up to 300 b.h.p. and also for homes. It can be installed quickly in practically any solid fuel boiler or furnace, old or new. Machines are shipped complete from the factory. All parts are standard and interchangeable. Features of Design and Construc tion--Construction and operation of the Iron Fireman are characterized by sim- plicity throughout. Outstanding fea tures of design and construction, are: (1) Pressed steel construction. (2) Special patented transmission--three speeds and neutral. Gears run in bath of oil. (3) Electric motor--standard make. (4) V-belt drive. (5) Safety shear pin protects mechanism from damage. (6) Quiet ball bearing fan supplying forced draft to fire. (7) Automatic fire banking damper--conserves fuel and holds fire in proper condition when stoker is idle. (8) Positive pneumatic fume eliminator--an auxiliary air supply that insures positive movement of all gases through the fire. (9) Volumeter that supplies exactly the amount of air needed for perfect com bustion regardless of fuel bed con ditions or type of coal used. (10) Sectional retort especially design ed to allow for heat expansion.. (11) Dead plates of heavy iron and ribbed. (12) Sec tional, self-clean ing tuyere blocks.

(14) Automatic electric controls designed for and used exclusively on Irpn Fireman. Automatic Controls--Iron Fireman starts and stops at the command of sensi tive, accurate automatic controls. Direct ing controls govern stoker operation according to demands of time, tempera- Iron Fireman Manufacturing Company Coal Burners, Automatic Domestic Installation--liin-Feed Model Domestic Installation--Hopper Model ture, or pressure. An example of the superiority of Iron Fireman directing con trols is the " Syncro-Stat " which provides automatic control of day and night tem perature. Other directing controls include pressure regulators, hot water and furnace regulators, and the "Timetactor," a device which runs the Iron Fireman during pre determined intervals in order to keep the fire alive during mild weather. The most important unit of the oper ating control system is the motor-driven relay switch. This device starts and ' stops .the stoker motor at the com- mand of the - Syncro-Stat or other directing controls. In the case of the larger stokers a magnetic Typical Inslallation operating switch Cast Iron Boiler works in conjunc tion with the relay switch. Iron Fireman for Homes--The Iron Fireman residential model employs "Forced Underfiring" principle-the same as larger machines, with simplified operation. Can be recommended for any steam, hot water, vacuum, or warm air furnace. Quickly installed. Hopper and binfeed models for both bituminous and anthracite coal. Anthracite models have been tested and ap proved by The Anthracite Insti tute. Typical Inslallation Domestic Boiler ENGINEERING SERVICE The Iron Fireman organization is nationwide. Trained men--backed by one of the largest manufacturing organiza tions in the field--are at your service to help you with the experience and practical heating information gained through servic ing thousands of boiler rooms and heating plants in all parts of the country. Any Iron Fireman engineer will gladly call and submit any additional informa tion requested. CATALOG AND INFORMATION Catalogs give full information about the Iron Fireman.
