Abstract

1,042,702. Fluid fuel furnaces; water tube steam boilers. BABCOCK & WILCOX CO Aug. 2, 1963 [Aug. 2, 1962], No. 30686/63. Headings F4A and F4B. A steam generator of the package type comprises a gas pass 19 alongside a furnace chamber 17 and containing steam generating tubes 22 connected between an upper drum 23 overlying the furnace chamber 17, and a lower drum 24, and a combustion chamber 51 of circular cross-section having wall tubes connected between the drums 23, 24. The furnace chamber 17, lateral gas passes 19 and passages 21 connecting the one end of the furnace chamber 17 to the gas passes 19 are enclosed within a casing having flues 87 connected to the gas passes, and provided over most of its surface with cooling tubes 28, 29, 30 connected between the drums 23, 24. The passages 21 contain superheated tubes 32, supported on vertical tubes 39, Fig. 6. The upper drum 23 projects beyond the front wall of the casing above the cyclone combustion chamber 51, which is enclosed in an air box 65 secured to the front wall of casing and to the upper drum 23. Burners 72 are arranged within a frusto-conical air supply sleeve 75 at the front end of the combustion chamber 51. Some air enters through the front end of the sleeve 75, and some enters through tangential inlets 75C formed in the wall of the sleeve 75. Further air is supplied through tangential ducts 76, Fig. 2, in the wall of the combustion chamber 51. Each duct 76 opens over the length of the combustion chamber 51, and has a row of gas burners 79. Further air is delivered to the throat 64 between the combustion chamber 51 and the furnace chamber 17 through by-pass air ducts 83 to tangential outlets 86 in the refractory throat lining. Dampers 85 control the amount of air delivered to the throat, which increases to about 30% at full load. The primary air from inlets 75C, the secondary air and fuel gas from outlet 76 and the by-pass air from outlets 86 whirl in the same direction. The supply of tertiary air through the front end of the sleeve 75 is restricted by the close spacing between the sleeve 75 and the air box casing, and the inlets 67 to the air box 65 are connected to a forced draft fan. Since the superheater tubes 32, Fig. 6, are heated by radiation at the rear of the furnace chamber 17 and by convection from the gases flowing to the passes 19 the steam temperature remains constant for a range of loads.
