Abstract

CFD (Computational Fluid Dynamics) was employed to simulate the combustion process in a waste incinerator and evaluate the effects of different variables on combustion. The research compared the distribution of furnace temperature and oxygen mass fraction at inlet air speeds of 5.36 m/s and 2.62 m/s. The results demonstrated that higher inlet air speed resulted in increased furnace temperature, reaching a maximum of 1719.4 K. Furthermore, the study investigated the impact of raising non-combustible substances to 50.2% on combustible substances during full combustion. The findings indicated that the presence of non-combustible substances reduced the maximum furnace temperature by 149.1K, diminished the high-temperature zone, impeded combustion efficiency and the decomposition of harmful substances, leading to higher emissions of harmful gases. The analysis suggested that optimizing waste incinerator performance could be accomplished by raising the inlet air speed appropriately and reducing the proportion of non-combustible substances, thereby enhancing furnace temperature and combustion efficiency.
