Abstract
[Purposes]As a typical clean heating technology,the biomass boiler plays a vital role in promoting the green transformation of clean heating in rural and urban areas.Here,the combustion process of biomass boilers is divided into solid-phase pyrolysis combustion and gas-phase combustion.By constructing a porous medium model and introducing combustible gas mass and energy source terms,the accumulation state of biomass fuel on the grate and the combustion phenomenon of primary air penetrating the fuel are simulated.Subsequently,the combustible gases are imported into the simu‑lation domain as source terms,and the gas-phase combustion is simulated by using the gas-phase chemical reaction model in Fluent software.[Methods]According to the combination of simulation with experiments,the impact of different air supply parameters on the internal velocity field,tempera‑ture field,and the distributions of carbon monoxide(CO)and nitrogen oxides(NOx)in the flue gas were analiped,and the important role of temperature distribution in combustion efficiency and pollut‑ant emissions was clarified.[Results]The consistency of simulation results with experimental data verifies the effectiveness and accuracy of the simplified model used in predicting the combustion behav‑ior of small and medium-sized biomass boilers.It can not only provide a theoretical basis for the opti‑mized design and efficient operation of similar biomass boilers but also provide scientific guidance for the innovation and application of clean heating technology.关键词
