山东省各火力发电厂由于燃用本省的高硫燃料,空气预热器的低温腐蚀十分严重。在过去未设防腐措施时,一般只能运行1～2年,甚至更短的时间就被迫大量更换管子。六十年代初,各厂都在积极寻找解决这一问题的措施,其中之一就是采用玻璃管空气预热器。1965年5月博山发电厂8号炉上首先安装了一整组玻璃管空气预热器作为运行试验。十年来,据不完全统计,山东各电厂先后已有16台锅炉上改装了玻璃管空气预热器,目前投入运行的有13台(另3台因各种
Shandong Province, due to burning coal-fired power plants in the province’s high sulfur fuel, air preheater low temperature corrosion is very serious. In the past there was no anti-corrosion measures, the general can only run for 1 to 2 years, or even a shorter period of time was forced to replace a large number of tubes. In the early 1960s, various factories were actively seeking solutions to this problem. One of them was the use of glass tube air preheaters. May 1965 Boshan Power Plant No. 8 furnace first installed a whole set of glass tube air preheater as a running test. In the past ten years, according to incomplete statistics, Shandong power plants have successively retrofitted glass tube air preheaters to 16 boilers. At present, there are 13 units put into operation
