环保：采用独特的除尘装置，水出渣系统，在正常运转中无颗粒粉尘产生，在完全燃烧时无烟气排放。其工作过程符合国家相关环保排放指标。
Environmental protection: adopt unique dust-cleaning equipment, water dregs system, in normal operation, no particles dust produced in complete combustion flue gas emissions have.
当我们清扫大街，燃烧或者过度放牧时，更多的粉尘，这也是一种喷雾状物，参与大气循环。
More dust, also an aerosol , circulates in the atmosphere when land is cleared, burned or overgrazed.
生产性粉尘是燃煤火电厂一大职业性有害因素，从原煤进厂到锅炉燃烧、排放的整个过程均有粉尘产生。
Productive dust is an occupational harmful factor of coal-fired thermal power plant. In the whole course from raw coal approaching to boiler burning and discharging the dust has been produced.
