装置。(1) Fluidized bed combustion device equipped with a fluidized bed that uses primary air to combust the coal sent into the furnace, and a secondary air blowing hole that combusts unburned coal in the empty column above the fluidized bed. In this method, the amount of primary air is increased in response to a decrease in the temperature of the fluidized bed during low load, and if the increase in nitrogen oxides due to the increase in the primary air exceeds the NOx reduction efficiency due to the decrease in the temperature of the fluidized bed, A fluidized bed combustion apparatus characterized in that a control mechanism is provided for adjusting the blowing position and blowing rate of the secondary air blowing hole to an oxygen partial pressure appropriate for reducing NOx.
