随着煤资源开采能力的限制及燃煤价格的调整,笔者公司热电部6#锅炉机组于2007年8月至11月进行了锅炉大修及燃烧神华煤改造。原有锅炉设计煤种为贫煤,由于神华煤高挥发份、易燃的特点,经再次设计改造,适当调整降低一、二次风温及燃烧器角度。改造完成后于2007年底点火试运,在启动过程中发生2次水冷壁爆管泄漏事故。 With the limitation of coal resource exploitation capacity and the adjustment of coal price, the 6 # boiler unit of the Company’s Thermoelectric Department carried out boiler overhaul and Shenhua coal reconstruction from August to November in 2007. Due to the high volatility and flammability of Shenhua coal, the original boiler design coal is lean coal. After being redesigned and reformed, appropriate adjustment is made to reduce the primary and secondary air temperature and burner angle. After the completion of the transformation, it was put into trial operation at the end of 2007 and two water pipe burst leakage accidents occurred during start-up.
