Early attempts to use welding instead of riveting for this style had not been accorded recognition by Kewanee until improvements engineered and worked out exclusively at the Kewanee plant qualified Type "C" to fill the definite demand for a dependable heating boiler adapted to restricted space. Backed by eighty years of boiler building experience Type "C" has won and kept first place in the industry as a compact boiler requiring less floor space yet maintaining unrestricted efficiency. It is a real boiler ... a scientifically designed and skillfully manu factured steam generator built to the ASME code for low pressure heating boilers and con forming with the ratings of the SBI code. This Type "C" welded model has become the accepted boiler for eve - operation served by steam of 13 lbs. pressir r less. 7L70 Series Hi-Firebox for Oil, Gas or Stoker Specification Table and Plan page 4 27L70 Series with Grates for Hand Fired Coal Specification Table and Plan page 5 The Kewanee Hi-Firebox Type "C" is Kewanee 27L70 series is rated for built exactly right for oil, gas or stokers. hand-fired coal and built with grates in The long water legs in this 7L70 provide the Hi-Rrebox which has the required essential height in the firebox to comply length of water legs to provide S B 1 with S B I code furnace height require code furnace heights for change-over to ments for mechanical firing. oil. gas or stokers using mechanical fired r Equipment: Steel base assembled with four cast iron comer posts, heavy ratings.

Flange steel plate, extra thickness is used. Tensile strength 50,000 to 60,000 pounds per square inch. This boiler plate is of homogeneous quality with high ductility and low carbon content (not exceeding 0.20?) as required for sound arc fusion welds. Construction: The requirements of the A. S. M. E. Code for low pressure heating boilers are fully complied with. In building Type C boilers there is applied all the skill in manufacture and all the approved procedure evolved by expert boiler makers throughout forty years of continuous practical experience. Fanciful and untried kinks are eliminated and a high degree cf workmanship is assured with no unnecessary shop expense. Contact surfaces on door castings are ground to dust-proof finish. Performance: Positive proof of actual performance beyond the specified duty is to be found in the figures derived from extended tests on the Type C boiler series made at Kewmee Boiler Corporation laboratory under practical operating conditions. The knowledge gained from this research has been so well applied in the design that the completed product carries handily all radiation loads up to the full catalog rating piut, for each size, with high efficiency. Backing: The name KEWANEE means as mueh on the new Type C boiler as it has meant for nearly half a century on all Kewsnee boilers. That is, the dependable heating service of Type C boilers is guaranteed by Kewanee. Design: Distribution of the materials of construction is so arranged to concentra most of the effective heating surface around the hot fire zone with a com quent quick transfer of more heat to the water. a. The water content is sub-divided so that there is ample volume at ail t; hottest parts, and aided by the header all the water is kept in active circu: tion, sweeping steam bubbles from the heating surfaces as fast as they formed thus permitting the absorption of more of the useful heat of con buation. U Although the circulation is rapid it is so orderly that the water level remair * steady. There is no danger of a dry crown sheet. No moisture or slugs : water 'are earned over into the steam main. C* With the high and wide steam space which is provided, there is plenty : room for a reserve supply of dry steam. J The disengaging area at the surface of the water line is unbroken and large enough to prevent priming which otherwise might be caused by crow ing the expanded bubbles at the moment steam is liberated. In other makes the Aues interfere with the liberation of steam as the wa:line is artificially lowered below the upper Aues which in consequence conn, even make steam. C. But in the Type C boiler the top rows of flues are under water, all the flu are effective m making steam. Grouping the flues in btnks not only permits free circulation of water a * around them, but it also offsets any tendency for sediment to become d posited and lodged thereon. The expanded gases are thoroughly strain? through these nests of Aues so that as much heat as possible is sifted ct during their travel to and fro their full length. g. In order to promote perfect combustion, there is extra width and heig; both in the furnace and in the rear combustion chamber. This gives tin for enough air to penetrate the fuel and mingle with the products of co~ bustion. An arch is arranged to deAect any unbumt gases over the glowir fuet bed at the rear. In this way combustion is completed and smoke eliminated at all loads. Uniform Rating "The ratings published in this catalog are in conformity with the Steel Heating Boiler Institute's Ccc for Rating Low Pressure Heating Boilers." Type C rating is Total Radiation Load at boiler outlet expressed in equivalent surface of cast iron radiators emittir, 240 units of heat or B. T. U.'s per square foot per hour for Steam, at 2 lbs. pressure and 150 B. T. U. for Water at IS degrees temperature. Total Radiation Load corresponds with the estimated design load which is the sum of 3 items -- 1. Normal heat emission of connected radiation required to heat the building to 70 degrees. 2. Maximum heat required for water heaters and other apparatus. 3. Heat emission of all mains and piping connections. Provided the stack and breeching connections are in accordance with the manufacturer's specification, each Type C Boiler will carry all the radiation load listed as its capacity, and in addition will easily handle large overloads with lor. firing periods and with low stack temperatures.

BURNS ANY KIND OF COAL, OIL OR GAS The question what fuel to use may be paramount for the users of other makes of boilers but not so for the purchaser of Type C. The owner of a Kewanee Compact Style Heating Unit has no difficulty with any fuel. The most available will Type C Boiler with Typical Stoker attachment Numbers 1749 to 1770--to Heat 2790 to 40.20Q Sq. Ft. of Equivalent Direct Radiation serve best. Even a change-over from one fuel to another presents no complications. With this wide adaptability in reserve, the customer may choose any of the Solid Fuels in various grades. Bitumin ous Soft Coals either for Hand Firing or with modern Stoker feed attachments. Powdered coal, briquettes, coke or processed fuels may be provided for as also may Anthracite Hard Fuel. For Liquid Fuel any oil burner on the market will pe: orm at its best with Type C. Wherever Gaseous Fuel is practicable, Natural Gs or the manufactured and synthetic varieties have been used for years with outstanding results under Kewanee Boilers. Those performances are not mere claims. The highly economical results are deduced from careful observations in elaborate tests. BASE GOES' INTO BASEMENT ALL READY ASSEMBLED Type C base consists of four substantial cast iron comer posts which take the weight of the boiler. The front plate is cast iron with balanced draft door and hinged frame which swings open to facilitate cleaning out the ash pit. The sides and back are heavy steel plate flanged over at top to hold jiler cover. Opening at rear has removable cover plate to permit cleaning out back of. bridgewall under rear combustion chamber. The complete base is shipped out from the factory fully assembled with grate bars,-shaker arms,' rods and levers in place all ready to operate after it is laid down on foundation with boiler shell set on top.

' o DIRECT DRAFT For Burning Oi Numbers 1749 to 1770 -- to Heat 2790 to 40,200 Sq. F: Equivalent Direct Radiatio: HE same predominant qualities which make the Kewanee Type C Boiler so well adapted for burn: T coal, apply just as emphatically in making this boiler suitable for burning oil. Extensive tests have been carried on in the laboratory at Kewanee during the last five or six ye with the purpose of developing ideal conditions as to boiler settings, furnace requirements, etc., burning oil with satisfactory results under all types and sizes of Kewanee boilers when equipped v. leading commercial oil burners. In view of the remarkably high efficiencies attained in numerous instances, we feel that Kewanee is well qualihe-: give expert advice to customers regarding the methods of installing any oil burners of recognized standing, for either fr or rear firing. As a matter of fact, blue prints will be cheerfully furnished showing foundation and setting plan recommer in each particular instance. It has become an axiom with experts in heating that "if you burn oil and expect to get steam, you must have a be that will steam just as well with coal or any other fuel." That is precisely what the Type C steel boiler will do. It give very high figures for efficiency with any kind of fuel. And whatever fuel may be under consideration, the pur Type C Oil Burning Boiler Settings--Front or Rear Fired chaser is sure of an economical "buy" in the Kewanee Type C steel boiler. That is to say the first cost will be moderate and the upkeep cos: which includes bo:h fuel bill and repairs will be low. Every dollar expended for fuel will produce a high percentage of heat units. The strong steel plate construction consisting of simple shapes compactly united by tr.e electric-weld method is done in the same shops where the well known Kewanee boilers have been made for 40 years. This is a guarantee that nothing is skimped in workmanship on Type C bo tiers. The well balanced features which make Type C a real boiler, designed on the scientific principles enumerated on previous pages, of the coal burning section in this catalog, also hold good for the oil burning boiler, proving its ability to fulfill a definite demand in the heating business for a boiler of minimum advisable dimensions for handling the load for which it is rated. 9}
