Abstract: Components of syngas always change with different gasification technologies and feedstock resources in coal-based IGCC and poly-generation systems. It is also difficult to get an unchanged syngas in a certain factory, so high fuel flexibility of gas turbine is necessary. This paper introduces the test results that different syngas (added with different quantity of purge gas) burn in the full-scale combustor test-rig and in-site gas turbine. When heat value and Wobbe Index of the fuel gas change in a large range, the gas turbine always operates safely and stably. This means the retrofitting gas turbine has high fuel flexibility. At last, it is suggested that giving different safe limits of fuel gas components according to different loads can improve the fuel flexibility and the economy of gas turbine plants.
