某电厂循环流化床锅炉采用燃烧煤泥发电,煤泥输送采用北京中矿机电工程技术研究所生产的MNS煤泥管道输送系统,于2003初投入使用。MNS煤泥管道输送系统是集煤泥搅拌处理、正压供料、高压泵送等多程能于一体的集成化系统,由煤泥搅拌仓、预压螺旋、浓料泵、分流器等多种设备组成。在经过半年多的运行后,煤泥搅拌仓多次出现联轴器断开,不仅使煤泥道输送系统无法正常运行,也严重影响了电厂的正常生产,制约了该电厂的经济效益的提高,采用燃烧煤泥的环保效益得不到充分发挥。
A power plant circulating fluidized bed boiler combustion coal slime power generation, slime transportation using Beijing Institute of Mechanical and Electrical Engineering MNS slime pipe production system, put into use in early 2003. MNS slime pipeline conveying system is a set of integrated system of slime mixing processing, positive pressure feeding, high pressure pumping and other multi-pass integration. The slime mixing silo, pre-compression screw, concentrate pump and shunt are many Equipment composition. After more than half a year of operation, the coal-mud mixing silo has many couplings disconnected, which not only makes the coal-silo conveying system unable to operate normally, but also seriously affects the normal production of the power plant, restricting the improvement of the economic benefits of the power plant, The environmental benefits of using coal slime can not be fully utilized.
