The operation Characteristic of Pilot-scale 2-Stage Coal gasifier

Pilot 규모 2단 형상 가스화기 운전특성 실험

Integrated Gasification Combined Cycle (IGCC) power plant converts coal to syngas, which is mainly composed with hydrogen and carbon monoxide, by the gasification process and produces electric power by the gas and steam turbine combined cycle power plant. The purpose of this study is to investigate the influence of gasification process to type and structure of gasifier. For this purpose, the performance characteristics of gasification reaction are analyzed with the operation characteristic of pilot-scale 2-stage coal gasifier. It is found that gasification reaction, floating characteristic of melted slag, particle stick of inside of the gasifier, particle stick and deposit of Syngas cooler are the causes in the different performance characteristics.
