摘　　要：结合两台配置不同制粉系统的超临界机组的RB试验情况,对超临界机组RB试验中的若干问题进行了探讨。介绍了RB试验的控制策略,指出正确设置主汽压滑压速率、锅炉主控目标负荷、给水控制速率,以及合理利用锅炉蓄热是RB试验中的关键问题。此外,应针对机组及设备的具体特点制定合适的控制策略。Based on analysis of the RB test of two supercritical units with different coal pulverizing systems, some problems of the RB test of the supercritical unit are discussed. Control strategiesof the RB test are introduced, and it is pointed out that the sliding pressure rate, target load of theboiler master, feedwater flow rate, and rational utilization of thermal storage of the boiler are thekey points in the RB test. In addition, appropriate control strategies should be developed for thespecific characteristics of the unit and equipments.
