对选择的燃气轮机热电联产系统的热力学性能,以第一定律和第二定律分析为基础进行了研究.探讨了余热锅炉设计中的喉部温差和工艺蒸汽压力对燃料利用率(第一定律效率)、电一热比、以及第二定律效率的影响.采用先进的工业燃气轮机的三个系统的结果清楚地表明,仅仅依据第一定律效率的性能评价是不适当的.决策者应发现本文中的方法在热电联产系统的比较和选择中是有用的.
The thermodynamic performance of the selected gas turbine cogeneration system was studied based on the first law and the second law.The effects of throat temperature difference and process steam pressure on the fuel utilization efficiency (first-law efficiency ), The electricity-to-heat ratio, and the efficiency of the second law.3 The results of the three systems using advanced industrial gas turbines clearly show that performance evaluation based on the efficiency of the first law alone is not appropriate.Decision makers should find that in this article Method is useful in the comparison and selection of cogeneration systems.
