- Analysis of Influence of Flue Gas Recirculation on Thermodynamic Performance and Economic Efficiency of 125 MW Supercritical CO₂ Coal-Fired Power Generation Unit
- “Flue gas recirculation can effectively solve the problem of overheating on the furnace wall of supercritical CO2 boilers. The research team took a 125 MW unit as the object and recommended a design with a 20%~30% recirculation rate through thermal calculation and economic analysis, providing a solution for the safe and economical operation of S-CO2 boilers.”
