To study the ash accumulation and pollutant emission characteristics of tri-combustion of coal; biomass; and oil sludge; a fluidized bed and settling furnace system is established for tri-combustion experiments. The effect of blending ratio (the ratio of biomass and oil sludge range from 30% to 50% and 10% to 20%; respectively) and biomass types are examined. The results show that HTB; coal; and oil sludge reach peak NO and NO2 production at approximately 100 s and 200 s of combustion; respectively; with NOx levels returning to zero around 300 s. SO2 peaks around 100 s and then gradually declines. The blending ratio of HTB:oil sludge:coal at 50%:10%:40% demonstrates the most effective control over NOx and SO2 emissions; reducing NO; NO2; and SO2 production by approximately 33%; 20%; and; 50%; respectively. In the ash with a ratio of Hutubi (HTB) + 50% oil sludge; the mass fractions of O; Si; Ca; Al; and Fe are approximately 27%; 23%; 8%; 12%; respectively. With the increase in the blending ratio of biomass and oil sludge; the mass fraction of Si in the ash rises; while those of Ca; and Fe decrease. © 2024 by the authors;
