암모니아 연료(NH3)를 연소용 공기(Air)와 혼합해 버너(30)에 의해 노(1) 내에서 연소시킬 때, 암모니아 연료를 개질기(20)로 안내해 암모니아 연료의 일부를 수소가스(H2)와 질소가스(N2)로 분해시킨 개질 암모니아 연료(NH3+H2+N2)를 버너에 공급하는 제1 공급로(11)와, 암모니아 연료를 그대로 버너에 공급하는 제2 공급로(12)를 설치하는 동시에, 노 내의 환경상태를 검지하는 노 내 환경검지센서(51)을 설치하고, 노 내 환경검지센서에 검지된 결과에 근거하여, 제어장치(60)에 의해 제1 공급로와 제2 공급로를 통해 버너로 안내하는 암모니아 연료의 양을 제어한다. This ammonia fuel combustion device is provided with a first supply path 11 which, when mixing ammonia fuel NH3 with combustion air Air and combusting this in a furnace 1 by means of a burner 30, guides the ammonia fuel into a reformer 20 and supplies to the burner a reformed ammonia fuel (NH3+H2+N2) obtained by decomposing a portion of the ammonia fuel into a hydrogen gas H2 and a nitrogen gas N2, and a second supply path 12 which supplies ammonia fuel without modification to the burner. An in-furnace environment detection sensor 51 is provided which detects the environmental conditions in the furnace, and the amount of ammonia fuel guided to the burner through the first supply path and the second supply path is controlled by a controller 60 on the basis of the result detected by the in-furnace environment detection sensor.
