我厂~#3、~#4、~#5炉都是链条炉,原设计每台炉都配有甲、乙两台二次风机。自链条炉加烧煤粉以后,对于二次风的使用便显得更为重要,虽然在二次风的使用上作过多次摸索和改进,但由于转速高,风压低,噪声大,耗电多,因此使用不正常,甚至经常停用。在大打省煤节电仗的时候,我厂为进一步降低飞灰可燃物,在改进制粉系统及喷燃器的 I plant ~ # 3, ~ # 4, ~ # 5 furnaces are chain furnace, the original design of each furnace are equipped with A, B two secondary fan. Since the chain furnace after burning coal powder, the use of secondary air is even more important, although the use of secondary air have made many exploration and improvement, but because of high speed, low wind pressure, noise, power consumption Many, so use is not normal, or even often disabled. In the big fight when saving electricity battle, I plant to further reduce fly ash combustibles, in improving the milling system and burner
