提出了应用甲烷重整技术的新型燃气轮机循环,建立新型燃气轮机循环系统的工作流程,并通过平衡常数的计算来分析燃烧室的反应平衡,研究了燃气轮机循环热效率的变化.结果表明:甲烷发生吸热的重整反应对甲烷燃烧的消耗量有影响;在相同燃料量的条件下,新循环与简单循环相比,热效率得到大幅提高;由于重整反应生成的混合气体组分中多了CO和H2气体,使得混合气体平均比定压热容增大;随着燃烧室出口温度T3的升高,新循环甲烷平衡的转化率逐渐增大,随着压比的增大,转化率逐渐降低.
A new type of gas turbine cycle with methane reforming technology was proposed and a new gas turbine cycle system was established. The equilibrium of combustion in the combustion chamber was analyzed by the calculation of equilibrium constants, and the change of cycle thermal efficiency of the gas turbine was studied. Of the reforming reaction on the impact of methane combustion consumption; the same amount of fuel conditions, the new cycle compared with the simple cycle, the thermal efficiency is greatly improved; as a result of the reforming reaction of the mixed gas components more CO and H2 Gas, making the average of the mixed gas than the constant pressure heat capacity increases; with the outlet temperature T3 of the combustion chamber, the conversion of the new cycle of methane balance gradually increased, with the pressure ratio increases, the conversion rate decreased.
