Intelligent ash conveying method and device for power plant

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of ash conveying in power plants, in particular to an intelligent ash conveying method and device for power plants. Background technique [0002] With the continuous development of science and technology, people's demand for the role of pneumatic ash removal system in thermal power plants is increasing. How to take into account the safety of the ash conveying system so as not to cause pipe blockage accidents and to minimize the energy consumption of the ash conveying process has attracted more and more attention. [0003] For the ash conveying system of power plant boilers, parameters such as the ash feeding time of the ash conveying system are often determined according to the amount of ash stored in the ash tank and the material level of the ash hopper. That is, the ash feeding time is often fixed after the unit is fully loaded, and the time parameter is adjusted to ensure the normal operation of the ash ...
