针对粤连电厂 42 0t/h无烟煤锅炉在试运期间发生多次退油灭火现象 ,进行了大量的稳燃试验研究。主要通过采用降低一次风速、调整各层二次风的合理配比、提高热风温度等措施 ,成功地实现了退油稳燃。试验结果对无烟煤锅炉的设计及安全运行有着重大的指导意义。
Aiming at the 4200t / h anthracite boiler in Yuelian Power Plant, many extinguishing and extinguishing phenomena occur during the trial operation, and a large number of steady-state combustion tests are carried out. Mainly through the use of reducing the primary wind speed, adjust the reasonable ratio of the secondary air, raise the temperature of the hot air and other measures, the successful realization of the return of oil stable. The test results have great guiding significance for the design and safe operation of anthracite boiler.
