| 摘 要： | 对DG1025/18.2- Ⅱ15型W火焰锅炉进行了燃烧调整试验,得出对配备D-11-D磨煤机的正压直吹式制粉系统,煤粉细度主要由一次风压决定,一次风压提高则煤粉变粗:二次风下倾后锅炉可大幅提高送风量,有效降低了飞灰可燃物含量;通过C挡板和F挡板的调整可改善氧量沿炉膛宽度方向分布不均的问题.经过燃烧调整,炉膛燃烧稳定性...

| Abstract: | The adjustment tests of combustion system were performed with a 300-MWe down-fired boiler.It is obtained that the pulverized coal-fineness mainly depends on the pressure of primary air and the coal-fineness will rise if increasing the pressure of primary air.The retrofit of the F-tier second air declination can enhance oxygen amount under operation at high load,which can lower the unburned carbon in fly ash.The problem of uneven distribution of the oxygen amount along the furnace width direction can be solv... |
