摘要
针对在给某燃气电厂机组管道来气调压时造成一定的差压能量损失的问题,提出一种利用膨胀机代替天然气调压器实现增压机前压力稳定并将膨胀机与增压机同轴布置的设计方案,介绍了该方案的布置及流程,分析了膨胀机出口天然气冷能的利用,并通过对比,从节约能源和经济性角度考虑,建议除电厂有多余的热量能对天然气进行加热外,一般不在膨胀机进气前设置加热装置来提高膨胀机的出力。
In one gas power plant, there is still a problem of a certain differential pressure loss even though an adjustment by pressure regulators. So, a design method to use expansion machines replacing the regulators was developed to achieve pressure stabilization of superchargers and make both expansion machines and superchargers in a coaxial location. Further, the utilization of naturalgas cold energy at the outlet of expansion machines was analyzed.Results show that it's unnecessary to add a heating facility to increase the capacity of expansion machines before gas in unless there is excess heat in this power plant to make natural gas warm.
