Study on Flow Field Uniformity at the Outlet of Denitrtion Reactor and Optimization of Diversion Structure

摘要

Due to the problem of reforming the reactor, the original supporting column at the outlet of the equipment has a negative influence on the uniformity of the flue gas. In this paper, CFD simulation technology is used to simulate the smoke movement at the outlet of the denitration reactor, using the standard k-ε turbulence model and mass transport model, the influence law of the column on the smoke is obtained, and the wedge guide plate is designed. The flow of flue gas is guided through the shape of the wedge splitters to improve the uniformity of the flue gas and eliminate the impact phenomenon of the economizer.
