KEWANEE fLAliN 1 Lt * tAilUlU AMERIC STANDARD 9 G--1 5-95L s l: e c c- L . 1 3^9D 24910 KEWANEEf This new steam generator is ideal (or office and store buildings, schools, motels, hospitals, small lactones, apartments and other build ings of medium size Intensive research, added to nearly a century ot boiler experience, produced this modern Square-Heat Generator with amazing com pactness, plus highest efficiency, plusKewanee Time-Proved structural features The secret of this remTrkable design, which results in highest efficiency, top-quality per formance, and long dependable service, is... exceptionally high proportion of primary (direct; heating surface which is many times more efficient than secondary (indirect) heat ing surface . . . plus. . . extra large furnace volume for complete combustion, smooth starts, clean Tiring, quiet operation, unre stricted gas Tow and low heat release The entire unit is listed by Underwriters' Laboratories, Inc 24911 .3 1 i = ,; ' \ < 1 THREE PA$S DESIGN Assures maximum heat transfer with low stack temperature ... highest operating efficiency. The targe firebox with arched upright crown sheet provides thorough mixing offuel and air... complete combustion before hot gases enter fire tubes. The second pass is rear to Iront through the direct fire tubes . the third from front to rear in the return tubes Gas travel is longer and there are no refractory battles to burn out and permit short circuiting of gases u;vi i V r; =! .AT [J :} = HIGH EFFICIENCY HEATING SURFACE Primary heating surface (exposed directly to the flame) is 4 to 15 times more effective than secondary heating surface (exposed only to hot gases). The Square-Heat Generator design utilizes nearly 50% greater ratio of primary to secondary heating surface than com petitive units. Square-Heat Generators provide MORE more effective heat transfer surfaces, and LESS less effective heat transfer surfaces. LARGE FURNACE VOLUME For complete combustion with smooth starts . . . dean firing . . . unrestricted gas flow ... quiet operation ... heat release averages 50% less than competitive units. FORCED-DRAFT OPERATION Provides ample combustion air for stub stack applications. Only a vent to the outside is needed. Special assemblies available tor high attitude installations. MORE ENERGY E PER SQUARE FOOT OF OCCUPIED FLOOR SPACE THAN ANY OTHER COMPARABLE UNIT COMPACT This Kewanee is the most compact generator you can buy. For example, you can have 80 hp in 42.7 square feet of occupied floor space Two principal competitive 80 hp generators require 72.7 square feet and 78.0 square feet, respectively. The illustration above shows the contrast. Head room also is minimum. 24912 LARGE STEAM SPACE Combined with abundant, unbroken disengaging area and ample water content assures steady water line and a plentiful reserve of dry steam. TUBES ROLLER EXPANDED All tubes are secured to tube sheets by roller expander--none are welded to tube sheets. WELDED STEEL Flange qoatity plate.

Class WATER HEATING COILS Standard Kewanee "Kl" (instantaneous) and "KT" (tank)) coils available for all units. Coil opening at front of trailer avoids inter ference with controls, wiring or breeching. EASY ACCESS TO TUBES Steel flue access cover with insulation securely keyed in place pro vides easy access to flues without disturbing fue! burning equipment TESTED-APPROVED ASME Boiler Construction Code requirements have been followed to the last detail ... and the Kewar ee name assures design and performance above and beyond arty code requirements. These gener ators have Underwriters' Laboratories listing. COMPLETELY ASSEMBLED With burner and all accessories--may be moved in by fork truck, hoist or rollers. Only service connections are needed to place unit in operation. 3 KEWANEE* Kewanee Square-Heat Generators are available for oil, gas, or combination gas-oil firing. Each Kewanee Forced Draft Burner is custom engineered for the generator it fires, assuring long, dependable and economical service. Two series of Kewanee Forced Draft Burners cover the entire range of boiler capacities and fuels. The Kewanee KR Burner fires light oil (Nc 2 CS12-48), gas, and combination gas-light oil in Units M-45 thru M-265. The oil burner is of the high pressure mechanical atomizing type, and the gas burner is of the multiple jet flame retention type. _ Units M-45 thru M-175 with the KR burner feature on-off operation (with low fire start on oil-fired Units M-135 thru M-175). Combustion air is regulated by a fixed position damper in addition to an adjustable primary-secondary air shutter. Units M-205 thru M-265 with the KR burner feature on-off operation with con trolled low fire start. Fuel and air supply are regulated for both high and low firing by a two position motor This provides smooth starting and top efficiency. The Kewanee Burner (Pressure Atomizing, tires light oil -No 2 CS12-48-, gas. and combination gas-light oil in Units h',-335 thru M-505 The oil burner is of the high pressure mechanical atomizing type, and the gas burner is o' the (lame retention type. The Kewanee Burner eAir Atomizing! fires No. 5 or lighter oil. gas. and combination gas-oil in Units N* -335 thru M-5C5 The oil burner is of the low pressure air atom'.zmg type and the gas burner is ot the flame retention type Units M.-335 thru N*-505 with the Kewanee burner feature lull mcdu'.aficr with proved low fire start Fuel and air supply are regulated throughout the firing range by a modulating motor controlled by a boiler mounted pres sure or temperature modulating potentiometer. 24913 MAXIMUM SAFETY Dull automatic main gas valves (on units over 1000 MBh input) provide added protection. Boiler passages are purged of combustible gases before and after each firing cycle. Combustion is continuously monitored by an electronic flame safeguard. CONTROL CABINET Programming and flame safeguard relays, switch ing relays, motor magnetic starter (if required), numbered terminal strips, indicating lights for major operations, and fuel selector switch-all mounted and wired in a heavy-gauge steel con trol cabinet mounted on the boiler unit. Wiring is ready for connection to a source of power. AIR-OIL UNIT The air-oil unit assembly of the Kewanee burner includes air compressor, oil pump, valves, bel! drive, motor, and all necessary accessories to provide the fine oil atomization required for clean, efficient oil tiring A thermostatically con trolled electric oil heater maintains uniform oil temperature to compensate for varying viscosi ties of residual oils The multi-louvered air pro portioning dampe' provides accurately measured air supply to match fuel supply for top operating efficiency at all firing rates 24914 M-45 thru M-265 e 24915 ftati*|-MBh.......... -- Honpower --Slum per towr-JlTF -- Steam (grou output) -- Steam (MCA wet) 1 tb* 4 ft.11 K Hj1 finni ratc-Cai 1.000 Btu/cu ft -Oil 140.000 Blu/fii . --Oil 1SO.OOO Btu/IJl Haatmg urface-Tolal Kfl --Primary id ft Furnace volume CM ft Safety valve capacity-Stiirr pei hi IbS ' Approi dry weight 1fbi ISO 13 4 464 1.I7S 1.410 563 j 4.0 --1 63 i 190 7.8 i 450 i1 1.900 1 ' \ t I *i (SO I 164 S67 U91 1.723 !
