Abstract

The invention provides a coal ash component prediction method and device and a terminal. The method comprises the following steps: acquiring coal parameters of target coal, wherein the coal parameters comprise coal components, coal shapes and coal quantity; obtaining combustion parameters of the target coal, wherein the combustion parameters comprise the combustion mode, the combustion duration, the primary air volume and the opening degree of a secondary air baffle; inputting the coal parameters and the combustion parameters into a trained component prediction model to obtain coal ash components of coal ash generated after the target coal is combusted under the combustion parameters, wherein the component prediction model is a BP neural network, and the coal ash components comprise mass fractions of various metal oxides in coal ash. According to the method, the coal ash component after coal combustion is predicted through the BP neural network, and the coal ash component can be determined before coal combustion, so that the coal ash component can be changed by adjusting the combustion parameters of coal, and the slagging and coking phenomena of the water cooling wall of the tail flue of the power station boiler are improved.

Description

technical field [0001] The invention relates to the technical field of detection of coal ash components, in particular to a method, device and terminal for predicting coal ash components. Background technique [0002] During the operation of power plant boilers, the tail flue will produce slagging and coking on the water wall. This is caused by the low ash melting point of pulverized coal. Therefore, the influence of the ash melting point of the coal used should be considered in the design and operation of the boiler. . The chemical composition of coal ash is the main factor affecting the melting point of ash. Therefore, to determine the melting point of coal ash, it is necessary to determine the chemical composition of coal ash. [0003] At present, the chemical composition of coal ash can only be measured after the coal combustion is completed, so the melting point of the coal ash can only be determined after the coal combustion is completed. It is difficult to avoid the ...
