| Abstract: | The cause of coal plugging in a boiler coal bunker and its influence on boiler running are analyzed. Taking the positive pressure direct-fired pulverizing system with middle-speed-mill as a case, through the import of boiler charge, adopting the control strategy for pre-estimating in advance, by means of specialized loosen machine, not only the coal plugging in a boiler coal bunker can be resolved radically, but also the sensitivity of control system and the safe intensity of loosen machine can be guaranteed . |
