摘要: 落煤斗堵煤一直是困扰热电厂循环流化床锅炉运行的重要问题。在总结其他电厂经验的基础上,结合自身实际,对给煤系统进行改造,以双曲线型煤斗代替方锥形煤斗并对播煤风系统进行了改造,有效地解决了落煤斗堵煤问题,即使在阴雨天气的情况下也能够畅通上煤。

Abstract: The coal jamming in coal hopper is an important problem perplexing the operation of the circulating fluidized bed boiler in power thermal plant at long time. Based on the experiences of other power plants, combining with actual situation, the coal feeding system was reformed. The square cone coal hopper was replaced by hyperbolic coal hopper, the coal spread wind system was reformed too. The problem of coal jamming in coal hopper was resolved effectively, so the coal feeding is unimpeded even at rainy days.
