为了运输发电厂干排的煤灰,在锅炉除尘器灰仓壁安装螺旋输送机,把煤灰直接输入散装灰车运走。这种集灰方式较原使用的仓式泵、螺旋泵及空气斜槽等气力输送方式具有投资小、结构简单可靠、占地面积小、操作维护方便等优点。这种集灰设备对老电厂由湿排灰系统改为干排灰系统尤为适用(图1)。 In order to transport the coal ash of the power plant’s dry-row, a screw conveyor is installed on the ash bin of the boiler dust collector and the coal ash is directly input to the bulk ash truck for transport. This ash collecting mode has the advantages of small investment, simple and reliable structure, small occupied area, convenient operation and maintenance compared with the original pneumatic conveying methods such as warehouse-type pumps, screw pumps and air chutes. This ash collection equipment is particularly applicable to the old power plant from wet ash system to dry ash system (Figure 1).
