To study the fuel control technology during fast cut back(FCB)process in thermal power units
the stratified modeling method was adopted to establish a centralized distribution parameter model for the furnace combustion zone.Evaluation indexes for temperature change in combustion zone were proposed.Moreover
this model was employed to simulate the FCB process when different coal mills were stopped.The results show that
the evaluation indexes can forecast the overall temperature change in combustion zone accurately.The operation scheme that stopping the mills in upper layer first
then the ones in the bottom layer and keep the ones in the middle layer can control furnace temperature and main steam temperature well.
