METHOD OF OPERATION OF VERTICAL TETRAHEDRAL FURNACE FOR SIMULTANEOUS BURNING OF GASEOUS AND POWDERED FUELS Russian patent published in 1997 - IPC

FIELD: boiler of thermal power stations burning organic fuels. SUBSTANCE: method consists in introducing the dust and air flows at deficit for complete combustion through burners fitted on one wall; introducing the gas and air also at deficit for complete combustion through burners fitted under pulverized fuel burners on adjacent walls; compensating flows of air are for afterburning through nozzles above fuel flow fed from wall where pulverized fuel burners are fitted and from opposite wall. Air flows are fed from opposite wall towards each other; consumption and rate of flow of air through nozzles fitted on wall holding the pulverized fuel burners are equal to (1,5-4,5)v_o and (0,8-2,5)w_o, respectively, where v_o and w_o are consumption and flow rate of air escaping through nozzles from opposite wall, cu.m/s and m/s. EFFECT: enhanced efficiency. 4 dwg
