摘要： A combustion device (C) burns a fuel in a combustion chamber (N) by using combustion air. The device includes a reducing agent injection device which includes an injection port (2n) and injects a predetermined reducing agent from the injection port (2n) toward a region (Kc) having a low oxygen concentration in a flame (K) in the combustion chamber (N), in which the reducing agent injection device changes a distance of the injection port (2n) with respect to the flame (K) in accordance with an injection amount of reducing agent.
