最近应城县盐厂对 DGF_4-13型半沸腾水管锅炉进行了改造。将高炉膛型燃烧室改为低炉膛燃烧室;有效地利用炉子空间高度和增加锅炉出力;采取倾斜往复推动炉排燃烧设备,实现机械化进煤;在低炉膛前部设有双曲线抛物线吊拱,炭粒能得到充分燃烧,为劣质煤的燃烧和消喷除尘创造了有利条件;在炉子标 Yicheng County Salt Factory recently DGF_4-13 semi-boiling water tube boiler was transformed. The blast furnace chamber is changed to a low chamber combustion chamber; the space height of the furnace is increased and the output of the boiler is increased effectively; the grate combustion facility is inclined and reciprocated to realize mechanization into the coal; and the hyperbolic parabolic suspension , Carbon particles can be fully burned for poor combustion of coal and eliminate spray dust created favorable conditions; in the furnace standard
