The invention provides a thermal power station boiler combustion adjusting model obtaining method based on data excavation, which can guide unit operation in a historic optimal state under each working condition. The method comprises an on-site sensor used for collecting boiler state information, a plant' s level supervisory information system (SIS), a decentralized control system (DCS) and a combustion optimization work station in connection with the SIS. The method takes full advantage of computer technology and database resources, researches and analyzes large amounts of unit operation data stored in a database for a long time, extracts valuable information from the unit operation data based on a data ''soft'' optimization thinking method, creatively obtains an optimization model for guiding unit operation in a certain mathematical method, and allows a unit to operate in the optimal state of high efficiency and low emission. The thermal power station boiler combustion adjusting model obtaining method contributes a lot to the development of power plant informatization process in our country.
