H₂/CO 합성가스와 메탄의 GE7EA 모사가스터빈 연소성능시험

IGCC technology makes it possible to utilize the low cost and clean electricity generation from coal, biomass, petroleum coke, wastes and etc. On top of that, IGCC is pre-requisite to develop the technology of CCS and hydrogen generation from coal. This study was conducted to verify the combustion performance of synthetic gas and to identify potential problems when synthetic gas is fuelled to a gas turbine. GE7EA gas turbine of Pyong-Tak power plant was selected for this study. Combustion tests were conducted by comparing hydrogen and carbon monoxide synthetic gas with methane, which is a major component of natural gas, in terms of combustion instability, NOx emission, and the exit gas temperature of the combustor. From the results of the fuel nozzle temperature we have ascertained that syngas is easy to flash back, and this property should be considered when operating a gas turbine and retrofitting a burner.
