Claims9
A combustion device, comprising:
- a burner including an ammonia injection nozzle having an injection port that faces an inner space of a furnace;
- and
- an adjustment structure configured to adjust an opening area of the injection port
- wherein the burner includes a pulverized coal injection nozzle having an injection port that faces the inner space of the furnace, and
- wherein the combustion device further comprises a control device configured to control operation of the adjustment structure so that the opening area of the injection port of the ammonia injection nozzle becomes smaller as a flow rate of pulverized coal in the pulverized coal injection nozzle becomes higher.
