一、前言玻璃管空气预热器,在我国的电站锅炉上,从试用到推广有近20年的历史。目前,全国约100台以上的电站锅炉改装了玻璃管空气预热器,积累了一定经验,在技术上已日趋成熟,并获得相当可观的经济效益。玻璃管空气预热器过去一般多用于较小容量的锅炉上,国内最大只在410t/h 锅炉上使用,在超高压670t/h 大容量锅炉上应用还是首次。京西电厂的

I. Introduction Glass tube air preheater, boilers in China’s power plant, from trial to promote the past 20 years of history. At present, about 100 sets of power plant boilers in the country have been retrofitted with glass tube air preheaters and have accumulated some experience. They have matured in technology and obtained considerable economic benefits. Glass tube air preheater used to be generally used for smaller capacity boilers, the largest domestic only in the 410t / h boiler used in high-pressure 670t / h high-capacity boiler application is the first time.
