The Analysis and Improvement of Coal Jamming in Coal Hopper of Thermal Power Plant

Abstract

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.

Key words: coal hopper, coal jamming, improvement measures, thermal power plant
