Abstract

Food waste contributes to environmental pollution and substantial economic losses during disposal. To address these challenges, there is a growing need to convert this waste into clean fuel for energy production. This study investigates the feasibility of utilizing food waste-based solid fuel(FWSF) by analyzing its combustion characteristics, flue gas composition, and ash deposition behavior when co-combusted with coal. The co-firing ratio of FWSF was varied from 0% to 30% based on thermal input. Thermogravimetric analysis revealed that FWSF undergoes slower pyrolysis compared to coal, while specific surface area analysis indicated a slower char combustion reaction for FWSF. During combustion tests in a 80 kWth furnace, NO emissions decreased as the co-firing ratio increased, attributed to the combustion characteristics of FWSF. Moreover, the rate of ash deposition remained comparable to that of coal combustion, even at higher cofiring ratios. These findings suggest that FWSF is a viable supplementary fuel for commercial coal-fired power plants.
