Intelligent ash conveying method and device for power plant

The invention provides an intelligent ash conveying method and device for a power plant. The method comprises the steps of acquiring the ash conveying parameters of the power plant, wherein the ash conveying parameters comprise the volume of an ash tank and a preset volume ratio upper limit; determining the ash inlet time and purging time according to the ash conveying parameters; determining theash deposition amount per unit time according to the flying ash proportion of ash contents corresponding to different coal types and the quantity of generated ash per unit time; and conveying ash according to the ash inlet time and the purging time when the proportion of the ash storage amount in the ash tank reaches the preset volume ratio upper limit. According to the intelligent ash conveying method, by considering the actual conditions of ash falling in an ash bucket, intelligent ash conveying is achieved, and the occurrence probability of ash clogging of a system is reduced; and meanwhilethe situation of resource waste is reduced greatly.
