Study on Flow Characteristics in a Novel Multiphase Reactor and Its Effect on Mercury Removal Efficiency in the Flue Gas
A novel multiphase reactor was established to experimentally study the flow characteristics in the duct at a power station and its effect on the mercury speciation distribution in flue gas and mercury removal efficiency. The simulated flue gas carrying mercury generated with special mercury generator enters into the reactor at different rates to simulate the flow field in different APCDs duct at power station. 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 efficiency of the mercury sorbent and fly ash. 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 not only help understand the principle that flow characteristics affects the mercury speciation distribution and mercury removal efficiency by absorbent and fly ash in the flue gas, but also help improve mercury removal efficiency through optimizing the flow field in the duct so as to reduce mercury pollution emission in the flue gas.
