^1 bulletin 749D (revised november, 1962) 28712 Modern concept based on experienced engineering--conservative design and top-quality construction-assu'e you of highest efficiency, faithful performance, long dependable set vice These qualities have been proved in thousands of installations , . Kewanee has been the recognized leader in steel boilers for neatly a century. Ratings aie conservative--five square feet of heating surface per horsepower-providing adequate reserve capacity. Firing rates aie carefully matched to heating surface, name size and shape are matched to furnace dimensions. Furnace voiume is de iarge furnace tube Provides abundant volume for complete combustion and greater proportion of primary heating surface. Hot flanged furnace tube openings assure maximum permanent strength at junction of furnace tube and tube sheets. Location of tube near bottom of boiler affords maximum protection against low water. 1 f I i signed foi efficient combustion, a no direct heat absorbing sui faces are ample Construction meets 01 exceeds A.S.M E. Boiler Code requirements. These combined features assum operating efficiency of 80%. forced draft operation fJ i^ C All fire tubes in high and low pressure units are set into tube sheets by roller expander ... No tubes welded to tube sheets. Spinner blades in all tubes swirl hot gases against tube surfaces for longer gas travel and maximum heat transfer. Assures ample combustion air for stub stack applications. twe pass design Special blower assemblies available for high altitude. Eliminates refractory baffles that can burn out and short circuit hot gases to stack... Kewanee design avoids wasted fuel, costly shutdown and expensive repairs.

I Kewanee Scottie Junior Package Units are avail able for light oil, gas, or combination gas-light oil firing. Three sizes of Kewanee Forced DraftBurners are tailored to cover the entire range of boiler capacities. Each Kewanee Forced Draft Burner is custom engineered for the boiler it fires. Together they make an unbeatable team with carefully matched capacity and characteristics. Light oil (No. 2 CS12-48) and either high or low pressure gas may be fired efficiently. Kewanee burners offer long, economical service with minimum maintenance. Forced draft eliminates need for conventional stacks. oil burners Oil burners are of the mechanical pressure atomizing type com plete with motor, fan, oil pump, nozzles, electric ignition, oil filter, combustion controls and relays necessary for automatic operation. Oil piping is ready for field connection to oil supply. gas burners Gas burners are of the multiple-jet flame retention type com plete with motor, fan, gas-electric ignition, automatic and manual gas valves, gas pressure regulators, combustion controls and relays necessary for automatic operation. Gas piping is ready for field connection to gas supply. gas-oil burners Gas-oil combination burners include the features of both the gas burners and oil burners in a single unit. No burner modifi cations to change fuels--just a flip of a switch. 4 28715 PRIMARY SECONDARY PROPORTIONING SHUTTER approvals Units 20,30,40 and 50 feature on-off operation. Combustion air is regulated by a fixed position air inlet damper in addition to an adjustable primary air shutter. An electronic combustion safe guard and a programming timer assure safe operation with pre-purge and post-purge. Units 60, 70 and 85 feature on-off operation with controlled low fire start. Fuel supply and combustion air are regulated at both low fire and high fire to provide smooth starting and top operating efficiency. An electronic combustion safeguard and a program ming timer assure safe operation with pre-purge and post-purge. Units 100, 125 and 150 feature full modulating operation with proved low fire start. Fuel supply and combustion air are regu lated throughout the firing range by a modulating motor con trolled by a boiler-mounted pressure or temperature modulating potentiometer. Enforced low fire start is provided by an interlock on the modulating motor. Combination electronic combustion safeguard and programmer assures safe operation with pre purge, post-purge and proved ignition for both fuels. Entire unit listed by the Underwriters Laboratory iUL). Fuel burning equipment listed by Canadian Standards Association (CSAi; Fire Marshal, State of Massachusetts; City of New York Board of Standards and Appeals; and others maximum safety Dual automatic main gas valves provide added protection against valve leakage. Boiler passages are purged of possible accumu lation of combustible gases both before and after each firing cycle. An electronic flame safeguard continuously monitors combustion. burner firing head Exclusive design of burner firing head provides quiet, stable combustion of gas or oil at all inputs. The recessed ring of gas burner ports permits partial premixing of gas and air at each individual port. Swirling high velocity main air supply assures intimate mixing of fuel and air for clean efficient firing. A separate manual adjustment of primary air permits stable operation under wide variations of gas pressure and other con ditions without objectionable noise or pulsation. control cabinet Master programming and flame safeguard relays, switching relays, necessary motor magnetic starters, numbered terminal strips, indicating lights for major operations and fuel selector switch--all are mounted and wired in a heavy gauge steel, dustproof, control cabinet. Wiring is ready for connection to source of power. 28716 scottie junior high pressure units UNIT NUMBER HX-20 HX-30 HX-40 HX-50 HX-60 HX-70 HX-85 H-100 H-125 H-150 Rating--horse power. -- MBh --steam per hour. 212F --steam radiation Firing rate--oil. 140,000 Btu -- gas Heating surface' Net furnace volume Safety valve capacity--steam per hour Outside surface to cover--uniacketed Approximate dry weight --125 lb.
