我厂10吨锅炉除炉底排灰工艺采用4个检结构灰斗积灰、蝶阀控制、定时手动卸灰、手推车排灰渣。由于这部分炉灰来自烟气中的飞灰及漏灰（鳞片式链条炉排工作时经缝隙挤压研磨漏下的粉状细灰），据测28％属呼吸件粉尘（粒径在5微米以下）对锅炉工及周围区域的职工危害极大；当操? I plant 10 tons of boiler furnace ash discharge process used in addition to four seized ash bucket fouling, butterfly valve control, regular manual unloading ash, truck row ash. As this part of the ash from the flue gas in the fly ash and ash leakage (scale chain grate work through the gap squeeze grinding leakage under the fine powder ash), it is measured that 28% of respiratory dust (particle size 5 Microns below) on the boiler workers and workers in the surrounding area is extremely harmful; when operating?
