Abstract
A method for rapidly changing the amount of pulverized coal supplied to a coal-fired furnace (10) equipped with a coal pulverizer (20) from a first steady-state level to a second steady-state level in response to a change in operating load demand. The amount of pulverized coal supplied to the furnace is instantaneously increased by providing pulverized coal to the furnace from a source (42) independent of the pulverizer or instantaneously decreased by diverting away from the furnace a portion of the pulverized coal being supplied by the pulverizer.
