中国首座煤气化之多联产示范工程已经运行2年多,基于该系统迄今累积的运行实践,计划将甲醇合成过程产生的弛放气掺入合成气中供给燃气轮机作为燃料,以达到优化工艺流程和节能减排的目的。燃气轮机燃料的改变,需要修改合成气喷嘴并进行燃烧室性能试验,本文在中压全尺寸燃烧室试验台上,对该型合成气燃烧室(修改型)掺烧高氢弛放气进行了燃料耐受性试验。试验结果表明,燃烧室头部锥罩温度和火焰筒壁温都位于允许的范围,燃烧室出口温度场品质有略微降低,燃烧稳定性有略微改善,NO_x排放浓度呈现增加趋势。
China’s first coal-fired polygeneration demonstration project has been running for more than two years. Based on the accumulated operational practices of the system so far, it plans to incorporate the purge gas generated by the methanol synthesis into the syngas to supply gas turbines as fuel to optimize the process And the purpose of energy saving. Gas turbine fuel changes, the need to modify the synthesis gas nozzle and the combustion chamber performance test, this paper in the full-size medium-pressure combustion chamber test bench, this type of synthesis gas combustion chamber (modified) Tolerance test. The experimental results show that the temperature of the cone cover and the wall temperature of the flame tube are within the allowable range, the temperature field at the outlet of the combustion chamber slightly decreases, the combustion stability improves slightly, and the NO_x emission concentration increases.
