Abstract:
To provide a pulverized-coal burner capable of stably igniting and burning pulverized coal without reference to a burner burning amount.SOLUTION: A pulverized-coal burner has opening/closing valves 18a-18f interposed in respective pulverized-coal injection nozzles 10a-10f, and also comprises an opening/closing controller 19 which performs opening/closing control over the respective opening/closing valves 18a-18f based upon an air blow amount of a pressure feed fan 12 that a pulverized-coal pressure feed pipe 13 comprises. Then the opening/closing controller 19 opens and closes the respective opening/closing valves 18a-18f to increase or decrease the number of nozzles to jet pulverized coal, and the jet of the pulverized coal is thus maintained at a flow rate suitable to stable burning without reference to a burner burning amount.SELECTED DRAWING: Figure 1
