In IGCC plants, operating characteristics of a gas turbine change due to design options such as the integration between the gasification process and the gas turbine. Problems of compressor surge margin reduction and turbine metal overheating may occur in low integration degree region. The syngas composition also affects the gas turbine operation. According to gasification process and kinds of coal, syngas compositions vary. Moreover, when carbon capture and storage is applied to the gasification process, syngas composition changes very much. This study examines the influence of syngas composition on the operating characteristics of a gas turbine. Four different syngases are considered as fuels of a gas turbine. As the heating value of syngas gets lower, the problems of surge margin reduction and metal overheating become worse. It is suggested that according to each syngas composition, integration degree of gas turbine and gasification process should be designed differently.

Integrated Gasification Combined Cycle (IGCC) technology is a power generation process that integrates a gasification system with a combined cycle power plant. This present paper describes concepts of the real-time operation monitoring system as a tool for enhancing the reliability and raising the availability of the first Korea IGCC power plant. This system consists of five (5) modules : (1) Data Validation Module, (2) Performance Calculation Module (3) Performance Diagnostic Module, (4) Trip Information Module, and (5) Statistics Analysis Module. The objective of this system is to achieve the optimum level of operational performance by providing the operation information of the entire power plant and its major components in real-time and on-line.
