Abstract
A coal-air synchronous dynamic coordinated control method for a coal-fired unit is provided, comprising: determining functional relationship between unit loads and designed coal feed rates and functional relationship between unit loads and flue gas operation wet-basis oxygen contents, respectively; obtaining a theoretical wet flue gas volume and a combustion-supporting dry air volume per unit mass of burning coal, and calculating an actual combustion-supporting dry air volume per unit mass of burning coal; calculating an actual low calorific value of feed coal; calculating a combustion-supporting dry air volume and an outlet wet flue gas volume; according to the target value of load instruction at a future time point, calculating a coal feed rate variation and a combustion-supporting dry air volume variation; obtaining an operation wet-basis oxygen content variation; and obtaining target values of the coal feed rate and the operation wet-basis oxygen content to be adjusted.
