1.锅炉尾部烟气余热加热凝结水方案1.1方案采用复合相变换热器技术有效控制酸露腐蚀的低温余热回收的方法。1.2工作原理复合相变换热器是在多根并联的密闭管排束构件内利用软化水相变潜热传递热量,在热管下端面加热,水吸收热量汽化为饱和蒸汽,在一定的压差下上升到热管上端面,向外届放出热量,并凝结成液体,饱和水经汽水分离器回到受热段,并再次汽化,往复循环,完成了把热 1. Boiler tail flue gas waste heat heating condensate solution 1.1 program The use of composite phase change heat exchanger technology effectively control acid dew corrosion low temperature waste heat recovery method. 1.2 Working principle Composite phase change heat exchanger is a multi-rooted parallel tube closed tube bundle member using latent heat of demineralized water transfer heat transfer in the heat pipe at the lower end of the heat absorption of water vaporized into saturated steam at a certain pressure Rose to the heat pipe on the surface, the heat released to the outside, and condensed into a liquid, saturated water through the separator back to the heated section, and again vaporized, reciprocating cycle, completed the heat
