Numerical simulation of brown coal combustion in a 550Â MW tangentially-fired furnace under different operating conditions

- CFD modeling study was performed for the combustion of the brown coal in a large-scale tangentially-fired furnace.
- Performance of the boiler under ten different operating conditions was investigated.
- The temperature distributions were better when the turned off burners are set in the opposite direction.
- The results showed improvements on the combustion characteristics in comparison with the standard operating case.
