For a large-capacity high-parameter coal-fired power plant, the raw coal consumption of each unit per day is about ten thousand tons. Such large coal consumption requires stable and reliable operation of the fuel supply system. However, due to factors such as weather factors, increased water content of supplied coal, and internal components and contents of different coal types, coal breakage often occurs during the supply of raw coal from a raw coal bunker to a coal feeder. Once coal breakage occurs, the supply of the coal pulverizing system is interrupted, the load is greatly fluctuated, the system is unstable, and the flame combustion characteristic, the steam temperature characteristic and the like in the hearth are greatly influenced. Frequent coal cutting off, unstable flame in the hearth, and oil feeding for stable combustion in serious conditions, which causes great economic loss.
Currently, coal fired power plants mostly employ raw coal silos in front of coal feeders to store coal. The raw coal bin is generally in a conical structure, and the blanking bin section is easily blocked, so that the normal operation of the equipment is seriously influenced, and the consequence is very serious. Clear stifled machine of former coal bunker of rotation type like present commonly used is equipped with the scraper at the rotatory storehouse internal in middle part, and clear stifled scope of this kind of scraper structure is not big, and is clear stifled effect also not ideal to the explaiing of material, and the material diameter is too big also can lead to former coal bunker to block up, to this, this application has provided one kind and has gone into stove coal flow intelligence management and control and prevent stifled device.
