摘要：
The simulated flue gas carrying mercury generated with special mercury generator enters into a multiphase flow reactor with different modes and the mercury sorbent was injected into the reactor at different rates and modes to study the effect of the flow characteristics and sorbent injection modes on mercury removal efficiency in flue gas. The studied results have demonstrated that different flow characteristics in the reactor affect the mercury speciation distribution in the flue gas, and it also affects the mercury removal efficiency. The possible reasons are that different flow characteristics makes the contents in the flue gas be with different resident time in the reactor and affects the chemical reaction between the contents with mercury, so that mercury speciation distribution in flue gas changes. The results will help improve mercury removal efficiency through optimizing the flow field in the duct so as to reduce mercury pollution emission in the flue gas.
