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...
In this paper, the sampling methods and digestion methods during mercury test in plants were reviewed and Aqua regia-hydrofluoric acid digestion and HNO3-H2SO4-V2O5 digestion were adopted to test plant samples located at a campus. The mercury testing results with two digestion methods were compared with each other, and the corresponding conclusions have been taken out.
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...
In this paper, fly ash sampled at ESP inlet and outlet in a coal fired power station was analyzed, and its characteristics and effect on mercury removal were experimentally studied. It shows that particles consisted in the fly ash are mostly smaller than 50-100 μm , and some were even smaller than 10 μm. The main contents in the fly ash were attained through approximate and ultimate analysis. BET...
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...
Mercury is harmful to our health and environment, so research on mercury emission from coal-fired power station, the main source of anthropogenic mercury emission, is very important. In this paper, mercury emission and speciation in the flue gas from a coal-fired power station was measured by three methods, i.e., OHM (Ontario Hydro method), Hg SCEM (semi-continuous emission monitors), and EPA Appendix...
