Abstract

1367479 Convection circulation steam generator; tube walls for furnaces FOSTER WHEELER CORP 14 Dec 1971 [14 Dec 1970] 58034/71 Headings F4A and F4B A convection circulation steam generator comprises a rectangular furnace enclosure 12 having radiantly heated front and rear walls 14, 16 and side walls 18 formed from welded finned water tubes 68 which are increased in diameter, see Fig. 3, in the region of burners 70 formed in the walls of the furnace. The smaller diameter section of the water tubes gives relatively high flow for better cooling in the region E of the burners 70 and the tubes can be made small enough to permit the use of plain carbon steel tubing. The larger diameter tubing increases the surface area of heat absorption for a given periphery in the upper region. The hot furnace gases pass through an exit C to pass down a convection area D containing a superheater 40, an economizer 42, and a reheater 38. An inwardly projecting section 24 of the furnace walls diverts gases against tube panels 46 which are connected in the flow circuit upstream of further superheater tubes 48. The tubes 46, 48 cool the gases at the exit to within design limits.
