为回收烟气的低温余热,解决露点腐蚀问题,继发展了玻璃管换热器以后,涂塑管换热器又应运而生,并正在得到迅速的发展。美国、日本、法国等近年来积极开发涂塑管换热器。例如,美国 Latham 冷凝换热器公司开发的涂衬 Teflon(聚四氟乙烯)的换热器已于1984年2月应用于 Ciba-Geigy 公司蒸汽发生装置的三台燃气/燃油锅炉(锅炉总出力86260公斤/时),回收烟气余热。这种管壳式的换热器可将烟气冷却到46℃,而将锅
To recover low-temperature waste heat flue gas, to solve the problem of dew point corrosion, following the development of the glass tube heat exchanger, plastic tube heat exchanger and has emerged, and is rapidly developing. In recent years, the United States, Japan and France have actively developed plastic tube heat exchangers. For example, a Teflon (Teflon) heat exchanger developed by the Latham Condensing Heat Exchanger of the United States was applied to three gas / oil fired boilers (total boiler output 86,260 kg / h), waste heat recovery flue gas. This shell and tube heat exchanger can be flue gas cooled to 46 ℃, while the pot
