在生物质热解规律研究的基础上,建立了上吸式生物质汽化炉的数学模型。该模型充分考虑了炉内主要的物理和化学反应过程及其交互作用。通过对汽化炉内生物质高温分解、燃烧、还原和干燥等汽化过程进行模拟计算,得出炉层高度对燃气成分和炉内混合物温度的影响规律,为模型的进一步优化提供了理论依据。 Based on the study of pyrolysis of biomass, a mathematical model of the sucked-up biomass gasification furnace was established. The model takes full account of the major physical and chemical reactions in the furnace and their interactions. The influence of furnace height on the gas composition and the temperature of the mixture in the furnace was obtained through the simulation calculation of the pyrolysis process of biomass in the boiler, such as pyrolysis, combustion, reduction and drying of the biomass in the boiler, which provided a theoretical basis for the further optimization of the model.
