火力发电厂使用的燃料以煤为主，因此煤尘污染十分严重，特别是燃料车间的卸煤、输煤、给煤等工序是主要煤尘发生源。该车间采取以喷雾洒水为主，并辅以冬季车间保温和给喷雾用水加温措施，使小粒子互相粘结，加快煤尘沉降速度，降尘效果显著，现评价如下。实施湿式降尘前对该? Coal-based fuel used in thermal power plants, coal dust pollution is very serious, especially in the fuel plant unloading coal, coal, coal and other processes are the main sources of coal dust. The workshop to take the spray-sprinkler-based, and supplemented by winter workshop insulation and spray water heating measures to make small particles bonded to each other to speed up the speed of dust settling, dust effect is significant, are as follows. The implementation of wet dust before the?
