        Abstract: Taking the 2×1 000 MW unit in certain power station for example, this paper introduced the strategy of coal pulverizing control system and the working principle and fault phenomenon of cold and mixture air door. Combined with the characteristics of equipment routine maintenance and the unit operating economy, the site control loop of air door was carried out transformation. The operation effect shows that the transformation improves the stability of the unit operation and the effect of loop optimization is ideal.
        Key words: coal pulverizing control system; throttle control principle; loop transformation; loop optimization
