为了有效利用锅炉尾部烟气的余热 ,提高低温受热面吸热能力并延长其使用寿命 ,分别对龙凤热电厂 8台锅炉空气预热器进行钢管、玻璃管、搪瓷管换管改造。实践证明应用搪瓷管抗磨损、无腐蚀、无漏泄 ,经济效益显著。
In order to effectively utilize the residual heat of the flue gas in the tail of the boiler, enhance the heat absorption capacity of the low temperature heating surface and prolong the service life of the boiler, the pipe, glass tube and enamel tube replacement of 8 sets of boiler air preheaters in Longfeng Thermal Power Plant were respectively reformed. Practice has proved that the application of enamelled pipe anti-wear, no corrosion, no leakage, significant economic benefits.
