2022/1/1 · The influences of gas composition and properties on the combustion and heat transfer characteristics were numerically studied in a 320 MW coal-fired boiler in oxy-fuel combustion modes. The results show that the differences in the gas composition between the air-coal and oxy-coal combustion would significantly affect the flow, temperature, and heat transfer …
