Due to its harm to human health, mercury emission from coal combustion power stations has brought more and more concern. The existed APCDs such as bag filter, electrostatic precipitator and wet FGD may remove the oxidized mercury from the flue gas. However, they have no obvious removal efficiency on the elemental mercury. The main direction in the development of new mercury removal technology is to...
More and more concern has been put on the mercury emitted from power stations burning coal because of its harm to human health. Both of the US EPA and European Commission have set regulations on the mercury emission from the electric utilities. China also pays more and more attention to the mercury emission and starts to sponsor the projects relative to the mercury emission and its control. Mercury...
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...
In this paper, a novel computational scheme, local whole-information difference scheme (LWDS), was proposed to solve significant pseudo diffusion in recirculating flow zone during numerical simulation. In LWDS, the effect of all of the local around points on the control volume was considered to demonstrate the spatial characteristics of the flow, and the weighted value at each point is adjusted according...
