摘要
火力发电厂烟气脱硝装置中的入口烟道底部经常有积灰产生,同时由于入口与烟道一般较长,支点均位于烟道底部,积灰容易导致烟道变形,使附近膨胀节拉伸后破裂,导致系统运行产生隐患。文中介绍一种简单有效的输灰装置,它不需增加其他设备,不增加电负荷、不增加物料能源消耗;设备及管件少,施工量小,投入成本小;它能实现连续、低压、匀速输灰,对管道冲刷小,磨损小,对炉后空预器积灰影响小;它由普通钢材制作,制作方便,加工简单,不需人工干预可实现长期稳定运行。
Thermal power plant flue gas denitration device in the bottom ash entrance flue is often produced at the same time, because the entrance flue and generally longer, fulcrum are located in the bottom of the flue, flue dust easily lead to deformation, the tensile rupture near the expansion joints, resulting in hidden operating system. Introduces a kind of ash conveying device is simple and effective in this paper, it does not need to add other equipment, not to increase the load, without increasing the energy consumption of material; equipment and fittings, small amount of construction, the cost is low; it can achieve continuous, uniform, low ash, small, erosion of pipeline small wear of furnace the air preheater fouling effect; it consists of ordinary steel production, convenient manufacture, simple processing, without manual intervention can achieve longterm stable operation.
