文章从燃煤火力发电厂的烟气余热回收及低低温烟气处理出发，指出氟塑料换热器相比于金属换热器具有耐腐蚀、传热系数大、重量轻等特点，阐述了氟塑料换热器技术的特点及其在燃煤机组中的应用现状，包含：烟气余热深度回收系统、氟塑料MGGH系统、烟气中水回收系统、氟塑料管式GGH系统，对其各自的特点展开介绍，并对氟塑料换热器技术的应用前景进行了展望分析。%From the field of flue gas heat recovery and low temperature treatment for flue gas in the coal-fired units. This article pointed out that, comparing with the metal heat exchanger, the fluorine plastic heat exchanger have these char-acteristics, such as strong corrosion resistance, high coefficient of heat transfer, light weight. And the characteristics of fluo-rine plastic heat exchanger and its applicating situation in the coal fired units were elaborated, including:the deeply flue gas heat recovery system, media gas-gas heat exchanger system based on the fluorine plastic heat exchanger, the system of water recovery from the flue gas, the gas-gas heat exchanger system of fluorine plastic tube, the features of these routes were intro-duced,. In addition, the application prospect of the fluorine plastic heat exchanger was analysised.
