摘要：

To facilitate fuel interchangeability for industrial gas turbines, various kinds of fossil fuels including syngas from coal gasification and steel mill gases including Blast Furnace Gas (BFG) have been investigated by previous researchers to determine their viability as alternative fuels for power generation. In the present study, various syngas components produced from coal gasification were combined to produce a simulated mixed gas, which was fed into a pressurized gas turbine combustion test rig to determine the combustion characteristics. A scaled model of the 7EA combustor from GE was used to conduct a basic comparative study on the emission trend (NOx), exhaust gas temperature distribution according to the combustor pressure, syngas composition and dilution ratio at the fuel side. The major findings were that modification of the empirical formula for pressure affects NOx emission and nitrogen dilution ratio affects the temperature profile uniformity on the fuel side.
