According to the system, method and device, existing data resources are fullyutilized, the optimal adjustment of the combustion instruction is realized, and the technical problems that the boiler is likely to operate in a non-optimal operation curve range in an existing control system can be solved.

Description

technical field [0001] This patent directly relates to the technical field of boiler combustion optimization. Specifically, it relates to a data-driven and intelligent algorithm-based boiler combustion optimization system, method and device. Background technique [0002] With the rapid changes in my country's energy structure, the proportion of new energy sources such as wind energy and solar energy is increasing, and thermal power plants are currently facing increasing pressure. At the same time, boiler operation is affected by factors such as grid load, fuel type, and ambient temperature, and the actual operating status of the unit changes in real time. In order to realize the efficient and low-pollution operation of the boiler, it is necessary to optimize and adjust the real-time parameters of the boiler, such as coal supply volume, air supply volume, water supply volume, and burner swing angle. [0003] At present, the DCS control system adopted by the power plant boil...
