Zusammenfassung:The present invention relates to a nozzle tip-replaceable burner for a gasifier, a method to operate the same, and a gasifier employing the same, and more specifically, to a burner for a gasifier, which sprays solid fuel slurry and an oxidizer into the gasifier and which comprises: a fuel supply pipe which the solid fuel slurry flows into and is discharged; an oxidizer supply pipe which is away from the external surface of the fuel supply pipe for a certain distance and in which the oxidizer flows into the space between the oxidizer supply pipe and the external surface of the fuel supply pipe; a fixed nozzle which is placed on the discharge end side and comprises a fuel discharge hole through which the solid fuel slurry in the fuel supply pipe is discharged, and one or more oxidizer discharge holes through which the oxidizer in the oxidizer supply pipe flows; and a replaceable nozzle tip which is detachably attached to the fixed nozzle by an attaching/detaching means and has a fuel spray hole and one or more oxidizer spray holes. The present invention aims to provide a nozzle tip-replaceable burner for a gasifier, a method to operate the same, and a gasifier and a gasification system employing the same, which, when a nozzle requires replacement, it can be individually replaced to reduce costs. 본 발명은 팁 교체형 가스화 버너, 그 가스화 버너의 작동방법 및 그 가스화 버너가 적용된 가스화기에 대한 것이다. 보다 상세하게는, 가스화기 내부로 고체연료 슬러리와 산화제를 분사시키기 위한 가스화기용 버너에 있어서, 고체연료슬러리가 유입되어 토출되는 연료공급관; 상기 연료공급관의 외면과 특정간격 이격되어 이격공간으로 산화제가 유입되는 산화제공급관; 토출단 측에 구비되어, 상기 연료공급관 내의 고체연료슬러리가 토출되는 연료토출홀과, 상기 산화제공급관 내의 산화제가 토출되는 적어도 하나의 산화제토출홀이 형성된 고정노즐; 및 탈부착 수단에 의해 상기 고정노즐에 탈부착되며, 연료분사홀과 적어도 하나의 산화제분사홀이 형성된 교체용 노즐팁을 포함하는 것을 특징으로 하는 팁 교체형 가스화기용 버너에 관한 것이다.
