摘要
近年来,由于特高压建设的需求,我国北方新增了较多间接空冷燃煤发电机组,尤其是新建了较多1000 MW级大容量间接空冷机组,而冷端系统的损失是影响电厂热效率的最主要因素,本文主要对降低冷端损失的多种方案进行可行性讨论,对冷端系统的优化进行全面的研究探索。
In recent years,due to the demand of UHV construction,more indirect air-cooled coal-fired generating units have been added in northern China,especially more 1000 MW large-capacity indirect air-cooled units.It is well known that the loss of cold-end system is the most important factor affecting the thermal efficiency of power plants.This paper mainly focuses on reducing the loss of cold-end.The feasibility of the scheme is discussed,and the optimization of the cold end system is studied comprehensively.
