Simulation Research on Temperature and Components’ Concentration Fields of A Moving Bed Gasifier

The briquette oxygen-enriched gasification technology developed with traditional moving bed gasifier is a developing technology in line with our strategic policy of energy. In order to master the flow and reaction states of the existing gasifier, a computational fluid dynamics software was utilized to simulate in this paper. Based on the geometric model with atmospheric pressure gasifier corresponding to the actual operation, the two-way k-ɛ model, the fluid transport model and SIMPLE method was adopted to solve N-S equation and P1 model, so as to simulate internal temperature and components’ concentration fields. The simulation results provide theoretical foundation for further study on combustion in the gasifier, optimization of combustion process and guidance for production process improvement.
