| Abstract: | The general situation and allocation of measuring point of HG-670-12.7-535/535 type boiler pulverized coal system in Shuangyashan Generating Power Co. Ltd was introduced in the paper, and the level of medium control schemes of steel ball mill made in China and by foreign countries was also analyzed and discussed. Based on the analysis above, the control strategy combining fuzzy control with common proportional plus integral plus derivative control was used in the steel ball mill computer control system of the No.2 unit, which achieved the automatic control of the ball mill level of medium, prolonged the service life of the ball mill, decreased the electric Power consumption during pulverizing coal, met the requirements for automatic control of boiler pulverized coal system with easy operation character. |
