Abstract: The directfired pulverizing system adopted in a 600MW supercritical unit has larger delay time and inertia. Depending on the quantitative measurement of coal feed rate, the compensating system and the cascade control system, the requirements of boiler operation were satisfied. The problems occurred in operation process were analyzed; some effective measures were adopted, and the operation stability was ensured.
Key words: supercritical boiler, fuel control system, coal feed rate, cascade control, time delay
