Better Than

Along with the rapid development of electric power industry in China, the pollutant discharge limits are getting more strict, and WFGD (wet flue gas desulfurization) technology and its equipment have been greatly developed and extensively applied, in which the gas-gas heater (GGH) is adopted at lots of the power stations. The corrosion is a very important issue in GGH, and it is experimentally studied in this paper. Through experiment of polarization curves and the control variable method, a comparative analysis of the corrosion resistance between the commonly used materials of the GGH is made. The results have shown that the corrosion resistance with the heat transfer surface in GGH will decrease with the temperature increasing, but the enamel steel’s corrosion resistance and stability is strikingly better than that of others, and the increasing volume of corrosion resistance by plating enamel is remarkable.

So2 Pollution

The development of flue gas desulphurization technologies and the control and reduction of SO2 pollution from coal combustion have become a hot research topic due to environmental concerns. Carbonaceous and carbon supported desulfurizing sorbents have highly porous structures, large specific surface area and low production costs and can be widely used as desulfurizer. This paper provides a comprehensive review of carbonaceous and carbon-based desulfurizing sorbents, including active components, compositions of raw gas and effects of process operation conditions. It can be concluded that the use of char supported metal desulfurizing sorbents for removing sulfur dioxide from flue gas is a promising technology. Different aspects of applications of carbonaceous and carbon-supported desulfurization sorbents are discussed in detail.
