Numerical Simulation Research on a Fixed Bed Gasifier

Excerpt

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