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 (NO_x), 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 NO_x emission and nitrogen dilution ratio affects the temperature profile uniformity on the fuel side.

为了促进工业燃气轮机的燃料互换性，以前的研究人员已经研究了各种化石燃料，包括煤气化的合成气和包括高炉煤气（BFG）的钢厂气体，以确定其作为发电替代燃料的可行性。在本研究中，将煤气化过程中产生的各种合成气成分组合在一起，以产生模拟混合气，然后将其送入加压燃气轮机燃烧试验台以确定燃烧特性。使用GE的7EA燃烧室的比例模型对排放趋势（NO _x），根据燃烧器压力，燃料侧合成气成分和稀释比的废气温度分布。的主要结果是经验式为压力修饰影响NO _X排放和氮稀释比例会影响燃料侧的温度分布的均匀性。
