循环流化床锅炉直接燃烧煤泥在实践中的应用

为了消耗煤矿选煤厂在洗选中出现的废料煤泥,冀中能源股份有限公司矸石热电厂坑口自备热电厂循环流化床锅炉进行技术改造。热电厂结合选煤厂实际状况和工艺,改变传统的燃烧煤泥方式,采用了直接掺入煤泥的方式方法燃烧煤泥。省去了压滤机压滤煤泥过程环节和专用烧煤泥系统、设备环节等。工艺简单,经济实用。通过现有的3Χ75 t/h和1Χ130t/h循环流化床锅炉中进行的直接掺入煤泥燃烧方式的实际应用,效果良好,锅炉运行安全稳定,额定出力、蒸汽温度、压力等运行参数正常。

Circular Fluid-bed Boiler Burning Coal Mud Directly Practice Application

In order to consume the waste coal mud in coal preparation plant, Jizhong Energy gangue Electricity Plant pithead self- provided power plant circulating fluidized bed boiler was transformed technically. The Electricity Plant combined actual state and process of coal preparation plant, traditional burning coal mud was changed to directly adding coal mud, which saved filter press filter slime process link and slurry system, equipment, etc. The technology was simple, economical and practical. Through 3Χ75 t/h and 1Χ130 t/h circular fluid- bed boiler burning coal mud directly, which proved good effect, stable running of the boiler, rated output, steam temperature, pressure, etc were normal.
