METHOD OF COMBUSTION IN BOILING BED Russian patent published in 2003 - IPC

FIELD: industrial boilers, particularly for combustion of particulate solid fuel and combustible waste. SUBSTANCE: method involves feeding of primary blast air and following introducing of secondary blast air into over-bead volume from blowing-up zones towards stagnation zones in tangential direction to simulated body of rotation. Blowing-up zones and stagnation zones located under blowing-up zones in over-bead volume profile are formed by lining and/or furnace shields. Part of secondary blast air is supplied separately and/or together with fuel and entrained matter, entrapped beyond furnace. EFFECT: increased effectiveness of fuel combustion process and blast air usage. 2 cl, 1 dwg
