Distribution of the materials of construction is so arranged to concentrat most of the effective heating surface around the hot fire xone with a consc quent quick transfer of more heat to the water. The water content is sub-divided so that there is ample volume at all thhottest parts, and aided by the header all the water is kept in active circuit tion, sweeping steam bubbles from the heating surfaces as fast as they ar< ( Constriction: formed thus permitting the absorption of more of the useful heat of com bustion. ; U Although the circulation is rapid it is to orderly that the water level remain The requirements of the A.

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.

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 Xewanee Boiler Corporation laboratory under practical operating conditions. The knowledge gamed from this research has been so well applied in the design e. But in the Type C boiler the top rows of flues are under water, all the flue are effective in making steam.

Uniform Rating "The ratings published in this catalog are in conformity with the Steel Heating Boiler Institute's Code for Rating Low Pressure Heating Boilers." Type C rating is Total Radiation Load at boiler outlet expressed in equivalent surface of cast iron radiators emitting 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 18C degrees temperature. Total Radiation Load corresponds with the estimated design load which is the sum of 3 items -- 1. Normal heat emmion of connected radiation required to heat the building to 70 degree*. 2. Maximum heat required for water heater* and other apparatus 3. Heat enuauon of all mam* and piping connection*. Piov.ded 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 long firmg periods and with low stack temperatures. -v Ke-wajs ee, Steel Bsiler.

Ft. o' Equivalent Direct Radiation HE same predominant qualities which make the Kewanee Type C Boiler so well adapted for burning 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 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 witl 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. As a 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 boilf 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 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 Tor fuel will produce a high percentage of heat units. Type C Oil Burning Boiler Settings--Front or Rear Fired The strong steel plate construction consisting of simple shapes compactly united by tr.e eiectnc-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 boilers. The well balanced features w hich make Type C a real boiler, designed on the scientific principles enumerated cn previous pages, of the coal burning section m this catalog, also hold good for the oil burning boiler, proving its ability to fulfill a definite demand m the heating business for a boiler of minimum advisable dimensions for handling the load for which it is rated.
