  • FURTHER EXPERIMENTAL DEVELOPMENT OF CIRCULATING FLUIDIZED BED COMBUSTION FOR USE IN THE FIRING OF STEAM BOILERS WITH APPLICATION TO INFERIOR COMBUSTION MATERIALS AND COAL

Abstract

With a view to making use of a widely spread fuel range for energy conserving and environmentally harmless steam generation, a circulating fluidized bed firing system developed by Steinmueller for 1 MW thermal output has been installed. The enlargement of the cross section of the furnace in the lower part renders any fuel and additive conditioning unnecessary. All plant components have given proof of their functional capability. Widely differing coal grades could be burnt in this system with high efficiency and moderate pollutant emission. Within a period of 768 operating hours, the boiler load, primary to secondary air ratio and calcium - sulphur ratio were experimentally varied. The results demonstrate that this advanced technology of circulating fluidized bed firing with integrated steam generation is economically attractive as well.
