Evaluation of the performance of a power plant boiler

computational fluid dynamics software was used, with small or no modifications to the physical submodels,to predict the performance of a 500 MW e sub-critical coal fired boiler under air and oxy-fuel conditions when firingcoal, biomass, and a 20% biomass blend, for the same thermal input. The results suggest that for a wet recycle retrofit, the

Numerical Study on NOx Emissions of Methane Re-Combustion

The fuel staging combustion technology is a promising low NOx combustion technology for coal-fired boiler. In order to reduce NOx emissions, the burners of a 600 MWe coal-fired boiler are retrofitted in which methane gas is selected as a secondary fuel for re-combustion. The CFD models of combustion process are built to investigate effects of the methane gasratio on combustion process and NOx
