METHOD AND DEVICE FOR BURNING GROUND COAL Russian patent published in 1997 - IPC

Abstract RU 2078283 C1

FIELD: heat power engineering. SUBSTANCE: method comprises gas generation, afterburning and cooling gas in fluidized bed apparatuses in which fluidization is reached by the use of air and mixture of air with recirculation gases. After a fluidized bed apparatus each of the gas flow obtained is individually introduced into the furnace of a boiler for afterburning. The fluidized bed is maintained at the same level in all three apparatuses. Primary furnace processes are separated into three stages, the products obtained in the primary furnace being gradually burnt out. EFFECT: enhanced efficiency. 5 cl, 2 dwg
