Numerical investigation of the effects of air–coal ratio on combustion characteristics of a 600 MW w-shaped flame boiler under low-load conditions
Low-load operation has become increasingly common for large coal-fired power units due to the growing penetration of renewable energy. However, deviations of the air–coal ratio (ACR) from design values under low-load conditions can significantly affect combustion stability and pollutant formation. In this study, a thre...
