【 摘 要 】

The uniformity of velocity distribution is the key factor that affects the De- NOx efficiency. A three-dimensional SCR model of a 660 MW power unit is established by commercial software Fluent16.0 to obtain the flow field distribution in the reactor. Some optimization measures are put forward for the optimization of flow field. Finally, the distribution of flow field of AIG (Ammonia Injection Grid) section achieved desired effects.
