Boilers Leader Iron Works General offices: 3010 N. Jasper St., Decatur, Illinois New York 21 E. 40th Street Chicago . 451 W. Erie Street St. Louis 2091 Ry. Exchange Building KOOLSTACK BOILERS for OIL BURNING, COKE, and ANTHRACITE COAL Low Stack Temperature. Leader Koolstack Boilers operate with stack tempera tures of less than 300 deg. fahr. Economy is the result. Heating Surface. Koolstack Boilers have far more than the usual amount of heating surface. Fire Travel. Flue gases pass from com bustion chamber to the top of rear tubular section, then down through the tubes and out at the bottom. Economy. The unusual economy of Leader Koolstack Boilers is due to the fact the flue gases are held in the boiler until all of the effective heat has been released. Automatic Damper. Tempo rary draft acceleration at the initial firing period is provided by an automatic damper which by-passes the products of combustion direct to the chimney. This damper closes automatically when the stack temperature reaches 250 deg. For Oil, Coke, and Anthracite Coal. While this is primarily a boiler for Oil Burning, it shows remarkable performance records on Coke and Anthracite Coal. It is not intended for use with soft coal.

The amount of heating surface per unit of rating in the Coil Boiler is exceptionally high and is tremendously effective because it is within view of the flame, hence, capable of absorbing the radiant heat. NET RATINGS The Coil Water Tube Steel Boiler is rated on the amount of direct cast-iron radiation the boiler will carry. Example: A boiler rated at 800 ft. will carry 800 ft. of direct cast-iron radiation. A sufficient reserve has been figured in the rating to take care of piping, except where unusual con ditions exist, such as exposed piping, insufficient radiation, etc., where allowance must of course be made.
