CHARACTERISTICS I ) I Y Material: Th component part* consist of only seven simple shapes compacted together so as to Urait the bulk and shorten the seams. Float* steel plate, extra thickness is used. Tensile strength 50.000 to 00.000 pounds per square inch. This boiler plate is of homogeneous quality with high ductility and low ca/boo content (not exceeding 0.20) aa required for sound arc fusion welds. Construction: The requirements of the A. S. M. C. Code for lew pressure heating boilers are fully complied with. In building Type C boilers there is applied al! the skill in manufacture and all the approved procedure evolved by expert boiler makers throughout forty years of continuous practical experience. Fenciful end untried kinks are eliminated and a high degree of 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 senes made at Kewance Boiler Corporation laboratory under practical operating conditions. The knowledge gamed from this research has been so well applied in the design that the completed product carries handily all radiation loada up to the full catalog rating plus, for each sue, with high efficiency. Backing: The name KEWANEE means ai much on the new Type C bo>!er si it has meant for nearly half * century on all Kewanec boilers. That is. the dependable heating service of Type C boilers is guaranteed by Xcwaner. Design: ' Distribution of the materials of construction is so arranged to concmtri most of tha effective healing surface around the hot &/ 100c with a con Qucag quick transfer of more heat to the water. 31, The water content is sub-divided so that there Is ample volume at all t botteat parts, and aided by the header aU the water is kept In active nrcM tion, sweeping steam bubbles from the heating surfaces ss fast as they- i formed thus permitting the absof'ptioo of more of the useful heat of co bustioo. U Although the circulation ia rapid it Is so orderly that the water level remai steady. There is no danger of a dry crown sheet. No moisture or s.ug water'art carried over into the steam mam. C* With the high and wide steam space which is .provided, there is plenty room for reserve supply of dry steam. J The disengaging area at the surface of the water line is unbroken large enough to prevent priming which otherwise might be caused by crov ing the expanded bubbles at the moment steam is liberated. In other makes the flues interfere with the liberation of steam as the wtt line is artificially lowered below the upper flues which io consequence cans 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 itcam. / Grouping the flues in banks not only permits free circulation of water i around them, but it also offsets any tendency for sediment to become C posited and lodged thereon. The expanded gases arc thoroughly ttrain> through these nests of flues so that as much heat as possible is sifted o during their travel to and fro their full loigth. g. Ia order to promote perfect combustion, there ia extra width and br< both la the fumaec and in the rear combustion chamber. Thu give* or for enough air to penetrate the fuel and mingle with the product* of cor bustion. An arch is arrsnged to deflect any unoumt gste* over me j c*fuel bed at the rear. In this way combustion is completed and isnoct eliminated at all loads. Uniform Rating "The ratings published in this catalog are in conformity with the Steel Heating Boiler Institute's Cod for Rating Low Pressure Heating Boilers." Type C rating is Total Radiation Load at boiler outlet expressed in equivalent surface of cast iron radiators err..tt'-r 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. fer Watt: a: :! degrees temperature. Total Radiation Load coirespondj with the estimated design load which ii the sum of 3 itemi -- 3. Normal heat emission of connected radistion required to heat the building to 70 degrees, i- Mxximum heat required for water heater* and other apparatus. 5. Heat tmnnon of all mam* and piping connection*. Provided the stack and breeching connections are in accordance with the manufacturer's specification, each Type < 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. 17] Kewanee. Steel EiSiler vrV'^*' ........ .. - Type C 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 Number* 1749 to 1770--to Heat 2790 to 40,200 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 modem 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 perform at its best with Type C. Wherever Gaseous Fuel is practicable. Natural Gas 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 HEADY 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 .oiler 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 is laid down on foundation with boiler shell set on top.

Ft. c Equivalent Direct Radiation THE same predominant qualities which make the Kewanee Type C Boiler so well adapted for bumm: 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 year: with the purpose of developing ideal conditions as to boiler settings, furnace requirements, etc., fo: burning oil with satisfactory results under all types and sizes of Kewanee boilers when equipped wit! leading commercial oil burners. In view of the remarkably high efficiencies attained in numerous instances, we feel that Kewanee is well qualified t< give expert advice to customers regarding the methods of installing any oil burners of recognized standing, for either fror. or rear firing. Asa matter of fact, blue prints will be cheerfully furnished showing foundation and setting plan recommende 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 boilc that will steam just as well with coal or any other fuel." That is precisely what the Type C steel boiler will do. It wi 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 Settingi--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 cost which includes both fuel bill and repairs will be low. Every dollar expended for fuel will produce a high pcrcentageof heat units. The strong steel plate construction consisting of simple shapes compactly united by tr.e e]ec:r>c*\veid method js done in the same shops where the well known Kewa-,:e boilers have been made for 40 years. This is a guarantee that nothing is skimped in workmanship on Type C boilers. 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 heid 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.
