The Discussion of a New Exhausting Smoke Solution in Natural Draft Cooling Tower with Flue Gas Injection

First, the three-dimensional model of NDCT with flue gas injection and the boundary conditions was established by GAMBIT2.3 on the basis of structural parameter. On theFLUENT6.3 technology platform with self-designed program, it was found that: The new type NDCT with flue gas injection avoids a roll of low pressure zone created by smoke flue arrangement of conventional NDCT with flue gas injection. The throat corrosion of NDCT with flue gas injection was reduced, Uplifting performance of mixed gas be made up by the smoke and hot and humid air was improved. It provides some guidelines about optimizing structure of NDCT with flue gas injection and arranging flue reasonably.
