Boiler nitrogen oxide emission control method, terminal and storage medium

The invention provides a boiler nitrogen oxide emission control method, a terminal and a storage medium, and the method comprises the steps of acquiring a plurality of data samples according to historical data, wherein the input parameters of each data sample are working state parameters of a boiler and comprise adjustable parameters and non-adjustable parameters, and the output parameters are values of NOx emission; clustering the plurality of data samples according to the input parameters of each data sample to obtain t subsets, and training a preset model through each subset to obtain t sub-models; determining a target model in the t sub-models according to non-adjustable parameters of the boiler under a given working condition; determining a target function according to the minimum discharge amount of NOx at the outlet of the boiler, and optimizing the adjustable parameters of the boiler according to the target function and the target model to obtain optimized values of the adjustable parameters of the bo
