Fuel Switch Combustion Engineering

RAS offers coal-to-gas, and coal-to-biomass fuel switch studies. We have unmatched expertise and extensive experience on biomass cofiring and conversion projects. Our capabilities include:

  • Burner modification or retrofit

  • Evaluate impact of fuel properties on furnace combustion, (e.g., moisture content, particle size, volatile matter content, etc.)

  • Control of slagging and corrosion formation

  • Impact on furnace exit gas temperature and hence steam temperature and boiler efficiency

  • Application of emission control technologies

CFD used to predict NOx formation of furnace combustion with different fuels

CFD modeling of coal-to-wood conversion for a 500 MW wall-fired furnace. Modeling shows predicted NOx emissions between coal and  biomass with various NOx reduction technologies.

CFD predictions of combustion when switched from coal to biomass

CFD modeling of coal-to-wood conversion for a 500 MW wall-fired furnace. Modeling shows significant combustion differences between fuels and burner settings.
