Thermal power generating unit boiler combustion optimization control system

The invention relates to the technical field of boiler combustion control, in particular to a thermal power generating unit boiler combustion optimization control system which comprises an oxygen content collecting assembly. A steam temperature, feed water temperature, hearth temperature and air supply temperature acquisition assembly; a steam pressure, feed water pressure, hearth pressure and air supply pressure acquisition assembly; a steam flow, water supply flow, air supply flow and coal supply flow collection assembly; a drum water level acquisition assembly; a motor power acquisition assembly; a combustion waste gas collection assembly; a coal feeding amount adjusting assembly; an air supply volume adjusting assembly; a feed water amount adjusting assembly; an induced draft fan rotating speed adjusting assembly; and a slag discharge control assembly. The traditional adjustment limitation is broken through, a new adjustment reference index is given, and a positive effect is achieved for further improving
