FLARING METHOD OF PULVERISED FUEL AND DEVICE FOR METHOD'S IMPLEMENTATION Russian patent published in 2011 - IPC F23K1/00 F23C5/32 

FIELD: power industry.

SUBSTANCE: flaring method of pulverised fuel at which combustion process is performed in the volume of vertical furnace chamber separated as to height into primary combustion zone of fuel supplied through the main pulverised-fuel burners, secondary combustion zone of fuel and reduction of nitrogen oxides, into which the fuel is supplied through reducing pulverised-fuel burners, and tertiary combustion zone for afterburning of solid and gaseous products of incomplete combustion, which are supplied to it from secondary combustion zone. The number of pulverised fuel b₂, which is supplied to secondary combustion zone, is less than the number of pulverised fuel b₁, which is supplied to primary combustion zone, in ratio of b₁/b₂=6…3, pulverised fuel for primary combustion zone is formed with grinding fineness of , and pulverised fuel for secondary combustion zone is formed with grinding fineness of in ratio of , where k=0.4…1 is coefficient considering fuel reactivity.

EFFECT: invention allows increasing combustion stability of pulverised fuel and reducing the number of hazardous emissions to atmosphere.
