Effects of reaction pathway and particle heat absorption on gasifier：a numerical study
摘要
Abstract
The gasification technology is an efficient way to process inferior crude oil,unconventional oil and coal with lower emissions,and numerical simuation is an important method to reveal the complex flow and reaction behavior in the gasifier. In order to evaluate the influence of volatile reaction pathway and particle reaction heat absorption ratio,the Orimulsion gasification process in an entrained-flow gasifier was simulated with Eulerian-Lagrangian method. The homogenous reactions and heterogeneous reactions were described by the finite-rate/eddy-dissipation model and particle surface reaction model,respectively. The simulation results demonstrate that the reaction pathway of volatile mainly affects temperature and species distributions in the near-nozzle region,while those at the outlet of the gasifier change only slightly. However,the effect of particle heat absorption ratio is almost negligible due to the lower amount of fixed carbon in the Orimulsion and the small reaction heat of coke combustion.关键词
