Method for low load operation of a coal-fired furnace
Patent
·
OSTI ID:6893087
When a pulverized coal-fired furnace is operating at low loads, the primary air and pulverized coal stream discharging from the coal delivery pipe is split into a first and a second coal-air stream and independently directed into the furnace by tilting at least one of the streams away from the other, thereby establishing an ignition stabilizing pocket in the locally low pressure zone created between the spread apart coal-air streams.
