摘　　要：针对火电厂输煤系统的犁煤器配煤部分提出了犁煤器分档配煤方案,较好地解决了多个原煤斗同时缺煤存在竞争的情况,并给出了低煤位危险指标Dt的定义,用于表征在相同条件下,不同犁煤器配煤方案的优劣。给出了犁煤器配煤方案的具体决策步骤,可以指导设计人员完成自动配煤设计。最后通过仿真获得了不同配煤方案的低煤位危险指标Dt值,通过比较得出了分档控制方案比传统的不分档控制方案优越的结论。A multiple-rank coal dispatch manner of coal plough for the coal feeding system in the fossil power plant, which may do well with the event of several raw coal hoppers lack of coal at the same time is given. In order to figure the advantages and disadvantages of different coal dispatch manners under the same condition, it defines a low coal level danger index Dt. It also offers the coal plough multiple-rank decision-making steps, which can instruct the engineer to complete the design of auto coal dispatch. The simulation program can get the Dt value of different coal dispatch manner.
