The experimental studies on the optimization control of combustion and unit load have been performed using radiative energy signal (RES) based on a visual monitoring system of three-dimensional (3-D) temperature distribution installed on a 660 MW arch firing (AF) coal-fired utility unit. The results show that: (1) Real RES changes linearly with the unit power. The RES under different unit power is recommended to be controlled close to the linear fitted value of corresponding load as much as possible. (2) During the stage of load increasing or decreasing, the radiative energy should be strictly controlled within a reasonable range. (3) When the load is less than 500 MW, optimizing air flow by using RES can increase the net unit power of 5〜10MW with the same coal flow rate. It is potential to use RES for optimized combustion control of large-scale coal-fired utility units.
