trie City Iron Works STEARNS DIVISION Erie, Pa. WELDED STEEL HEATING BOILERS Sales nOffic--e---s--"in' Principal dries Cool Fired Typt Oil or Gat Fired The Erie City Welded Steel Heating Gas passes are correctly proportioned to insure Boiler is built in 18 sizes, 3,500 to 28,000 sq. ft. of steam radiation capacity, for coal, oil or gas firing. A few of the many features of design incorporated in this sturdy boiler that every heating engineer will appreciate are as follows: correct velocities through the different passes of the boiler. Draft loss is exceptionally low, making it pos sible to carry heavy fires without seriously reducing the steaming rate. The ratio of heating surface to grate area is above the average for boilers of this type. Many other characteristics of this boiler Specially designed water-cooled refractory arch are described in a booklet. Please write insures smokeless operation. for a copy for your file. Long travel of products of combustion through 3 in. fire tubes insures low exit temperature and high efficiencies. Large fire box and grate area permit extended firing periods and lees frequent ash removal. Front and rear smoke chambers are built into the boiler so that there are no protruding parts. In addition to the two types illustrated above, we build the Up-Draft type for-low volatile coals, which does not have, the water cooled hanging arch as built into the smokeless type and is, therefore, slightly lower in price.

Joliet, Illinois Heating Boiler Division of James G. Heggie & Sons, Manufacturers of Steel Boilers for Over 38 Years Representatives in Principal Cities For Burning Soft Coal Smokelessly For Soft or Hard Coal, Coke, or Wood For Burning Oil or Gas The introduction of Heggie-Simplex Boilers marked the beginning of a new era in heating boiler design and construction. While widely imitated today, they embody the simplicity in design upon which the durability, that has made them so popular, depends. Patents protect this superiority. The crown and side walls of the firebox and auxiliary combustion chamber are made from a single plate--there are fewer plates, and fewer seams in Heggie-Simplex Boilers than in other boilers of this popular type. While built to conform with the A. S. M. E. Code, its requirements are minimum only in Heggie-Simplex specifications. For example, where the Code calls for in plate, HeggieSimplex employ %6 in. All openings are rein forced with forged steel flanges. Bases are made of steel channels. Similarly, every de tail affecting greater strength and longer life is incorporated. S. H. B. I. Ratings Heggie-Simplex Boilers are rated in con formity with the "Steel Heating Boiler Insti tute's Code for Rating Low Pressure Heating Boilers." These ratings are the total radiation load at the boiler outlet; expressed in square feet of cast iron radiation. Steam ratings are based upon the emission of 240 B.t.u. per hour per square foot of rating at 2 lb. pressure. Water ratings are based upon the emission of 150 B.t.u. per hour per square foot of rating at 180 deg. fahr. To determine the Heggie-Simplex Boiler re quired to heat a building, add the following: (1) the direct radiation, (2) the'equivalent to compensate for losses through water heaters or other apparatus connected to the boiler, (3) and the equivalent to compensate for losses through piping connecting the -radiation, water heater and other apparatus'to the boiler. Then select a size with a rating equal to this total load. Send for catalog to obtain more de tailed information and specifications. 583
