Abstract:

Due to the aging of the coal handling system in the first stage of Hubei Huadian Xisaishan Power Generation Company Limited, the concentration of dust in the transfer station is quite high during the operation. The deviation of the belt, scattering of coal and the excessive concentration of dust are resulted from impropriate feeding point. With the change of the source of coal, the original coal handling system process seriously constraints the efficiency of production. Optimization is performed on coal handling process through reforming the transfer station, and optimizing the coal handling system equipment by using the curving coal dropping pipe and dust suppression guide trough at the same time. An automatic dust concentration monitoring and controlling system are added. The dust concentration in the transfer station can be reduced by methods such as utilizing the dustreducing equipment, which is analyzed by realtime data. Methods improve the working environment, improve the transportation efficiency, and obtain good economic and social benefits.
