Abstract
Co-firing is an effective approach to blending biomass sawdust with coal to reduce emissions and support the clean energy transition. The variation in fuel composition influences boiler efficiency, combustion performance, and emission characteristics due to differences in fuel properties and flow rates. This study investigates the effect of sawdust and coal blending at biomass ratios of 0%, 1%, 2%, 3%, 4%, and 5% on boiler efficiency using direct and indirect calculation methods, flue gas characteristics, Furnace Exit Gas Temperature (FEGT), and fuel flow rate. The experiment was conducted on a pulverized coal boiler operating under a load of 600–660 MW. Results indicate that increasing the proportion of sawdust decreases boiler efficiency for both calculation methods due to the lower calorific value of biomass compared to coal. Furthermore, higher sawdust ratios significantly reduce FEGT and emissions (SO₂, NOₓ, and CO₂), while flue gas levels tend to increase with greater biomass content. These findings suggest that incorporating sawdust in specific proportions can reduce emissions without significantly compromising boiler performance, making it a promising alternative fuel to enhance environmental sustainability in power generation
