江西省萍乡市化肥厂前几年前后安装了两台蒸发量分别为8吨/时和10吨/时的的全沸腾型锅炉,拟燃用厂区附连煤矿的煤矸石和厂内的造炉炉渣。由于对这类新型锅炉缺乏使用经验,再加上锅炉原设计上的某些不足,在试烧过程中常在煤矸石中掺入60%的优质烟煤才能燃用,而且常出现点火、压火困难,容易结焦黑火等情况,致使汽量不足,压力波动大,甚至停车。
Pingxiang City, Jiangxi Province, a few years ago before and after the installation of a fertilizer plant two evaporation were 8 tons / hour and 10 tons / hour of all boiling type boiler, burning plant with coal mines attached to the gangue and furnace Slag. Due to the lack of experience in the use of such new boilers and the lack of some original design of boilers, 60% of the high-quality bituminous coal is often burned into the coal gangue during the test burning process, and often ignition occurs and the firing pressure is difficult , Easily coke black fire and other conditions, resulting in insufficient steam volume, pressure fluctuations, and even parking.
