低温烟气余热发电系统最佳余热回收量的研究
|
摘要
获得最大发电净功率是余热发电系统设计的主要目标之一。建立一个以低温烟气为热源的余热发电模型,研究得出影响系统净输出功率的2个主要因素:系统余热回收量和余热锅炉排烟温度,其中,系统余热回收量即余热取热区域对系统优化具有关键作用。
To obtain maximum net power is the aim of waste heat power generation system design. A model is built to study the waste heat power generation of low temperature flue gas. The results show that the two main influence factors on net power output of the generation system are the total recovery amount of waste heat and the exhaust temperature of HRSG, while the total recovery amount of waste heat is key to system optimization.
