摘　　要："烟塔合一"技术,即取消火电厂中的烟囱,将锅炉经除尘脱硫后排出的烟气,经自然通风冷却塔排放到大气中。用等效热降的方法分析了"烟塔合一"技术增设烟气余热换热器的节能效果,并以660 MW机组为例,进行了几种方案比较。定量计算结果得出的结论对指导发电厂采用"烟塔合一"技术烟气余热换热器的设计具有重要的意义。The technology for ＂combining stack and cooling tower into one＂ means to delete the existing stack in the coal-fired power plant and emit the flue gas from the boiler through the natural ventilating cooling tower after desulfurization and dust removal. This paper analyzed the economic effect of the waste heat exchanger in natural draft cooling towers system on base of the equivalent heat drop theory. A 660MW unit is taken as an analysis example, economic effect of 4 scheme are compared. Quantificational results provides foundation for designing. The waste heat exchanger of natural draft cooling tower system.
