Both the Regular and the Smokeless types have the following distinctive features in common: Conservative ratings from actual tests according to the American Society of Heating and Ventilating Engineers Code the evaporative power and efficiency are exceptionally high; a long fire travel and all heating surface below the water line; a low steady water line with water gauge tapped directly into the section; dry steam guaranteed without a header and only one main outlet from boiler; grate bar connections of sectional boilers are outside the ashpit; all heating surface easily cleaned from front of boiler through large flue doors. The temperature of the gases in the first pass or lower flues is at least 200 degrees higher than in the fire box for an hour or two after firing due to the special mixing or carburetor feature of all Regular type boilers. In the secondary combustion chamber of the Smokeless type, the temperature at times exceeds 2000 deg. fahr. which means high efficiency due to proper combustion conditions as regards, time, temperature, and mixture. The INTERNATIONAL Economy Smokeless Boiler is an up draft boiler designed for the smokeless combustion of any bituminous fuels commonly used for heating purposes. It is built on the Kent Wing Wall principle in which the rear portion of the boiler contains a mixing chamber and a secondary combustion chamber, separated by a brick wing wall; so that the smokeless feature is entirely outside of the firebox. This type of boiler is very simple to control and does not require the services of a skilled or expert fireman. Cul-Away View of No. 140-4?
