Coal Quality Correction Circuit Based on Back Pressure Participation in Ultra Supercritical Intercooling Unit
Unstable back pressure has a significant impact on coal consumption,causing a mismatch between boiler heat load and electrical load,but the actual coal quality has not changed.However,the coal quality correction circuit will force the boiler load to be consistent with the electrical load,resulting in an imbalance of coal water ratio.The coal quality correction circuit was optimized by combining ultra supercritical intercooling units,eliminating the influence of back pressure changes on coal quality correction.
