Numerical Simulation Co-Firing Of EFB And LRC Injected At Different Burner Levels In Tangential Combustion-Type Pulverized Boilers

The exploration of biomass fuels is crucial for enhancing the economic value of solid waste from palm oil and mitigating the environmental impact of greenhouse gases emitted by power plants. This study conducted a numerical analysis on a pulverized coal (PC) boiler with co-firing at various burner positions. The numerical simulation results indicate that co-firing with empty fruit bunch (EFB) can enhance the ignition characteristics of Low Rank Coal (LRC). shown in the FEGT area an average increase in temperature of 0.2-0.45%. However, it should be noted that this temperature value is still within safe limits because it does not cause overheating of the heater. Furthermore, the formation of unburned particles can be reduced through the distribution of CO2. Additionally, the co-firing case 2 exhibits low NOx emissions, with a decrease rate of 24.6% when burner B is set at a condition of 1,63E-07. This condition is considered the most ideal as it is also accompanied by a significant reduction in SO2 emissions, ranging from 21.82% to 24.7%.
