电站锅炉空气预热器的腐蚀及堵灰造成了很大的损失,并使维护费用增加。在锅炉运行中由于冷端腐蚀及堵灰是造成出力降低、强迫停炉、设备更换费用增大及效率下降等的原因,这就促使发展一种更新更有效的方法来解决这些问题。用化学方法来解决的办法是将中和剂直接加入锅炉的冷端。先 Corrosion of boiler air preheaters and plugging of ash in power station caused a great loss and increased maintenance costs. Due to cold end corrosion and plugging ash in the operation of the boiler, the output is reduced, forcibly shut down, equipment replacement costs are increased and efficiency is reduced, which prompted the development of a newer and more effective method to solve these problems. Chemically, the solution is to add the neutralizer directly to the cold end of the boiler. first
