Boiler soot blowing control method and device, boiler control equipment and boiler

The invention discloses a boiler soot blowing control method and device, boiler control equipment and a boiler, and the boiler soot blowing control method comprises the steps that fire coal parameters and air distribution parameters corresponding to different operation loads of the boiler are obtained; according to the fire coal parameters and the air distribution parameters, a numerical simulation algorithm is adopted for calculation to determine a flow field distribution diagram, a temperature distribution diagram and a heat flux distribution diagram of the boiler under different operation loads; acquiring operation states of the boiler under different operation loads; according to the current operation state of the boiler and the characteristics in the flow field distribution diagram, the temperature distribution diagram and the heat flux distribution diagram, an easy-to-coke area of the boiler is determined; and installing a soot blower in an easy-to-coke area of the boiler. Therefore, the easily-coking a
