Boilers InTERn/mon/iL Heater Cocop/my Utica, N. Y. BRANCHES: CHICAGO NEW YORK NASHUA, N. H. CLEVELAND, O. 1933-35 Wentworth Ave. Broadway & 57th St. 369 Main St. 1441 Davenport Ave., N. E. Manufacturers of Heating Apparatus InTERn/mon/iL No. 8-47 International Economy Steam Boiler Economy Boilers On the following pages we present condensed data on the International Economy Sectional Boilers. Both the Regular and the Smokeless patterns have the fol lowing distinctive features in com mon : They will absolutely deliver dry steam to the system without the use of a special header. The grate bars have their connections entirely outside the boiler and shaking attachment may be placed on either side. They have a low water line. The water gauge is tapped directly into the section. Large doors give easy access for cleaning from the front.. They have a high evaporative power and they are conservatively rated from actual tests according to the A. S. H. & V. E. Code. In the regular pattern boilers provision is made so that tongues of flame pass up; between the sections of the crown sheet and thoroughly ignite the gases in the mixing chamber, as the lower row of flues is called. This is the well known carburetor principle which has always been a feature of Economy Boilers. The International Economy Smokeless Boiler is an up-draft boiler. It is built on the Kent Wing Wall principle so that the smokeless feature is entirely outside of the fire box and practically independent of the fireman. It has no special grates or arches in the fire box, holds several hours' supply of coal and requires the least possible attention. Excess air is al ways under control,--an im portant feature that pro motes fuel economy. Cutaway View of No. 130-47 Smokeless Boiler 228 International Heater Co.
