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.

Main Component

The peak of power consumption will be brought by the rapid development of the industry. Thermal power is still the main component of electric energy at present. More and more attention has been paid on the atmospheric pollution caused by the thermal power plant in our country. The sulfur dioxide (SO2), one of the thermal power plant flue gases, is dangerous to the environment and human. Effective SO2 control technology can not only reduce the environmental pollution but also the sulfur can be recovered in order to conserve resources.

Abstract MAT 21 is a nickel-20 chromium-20 molybdenum-2 tantalum alloy. The very high molybdenum and tantalum content gives excellent general, pitting, and crevice corrosion resistance. The alloy was developed to be resistant to sulfuric acid dew point corrosion. Applications include scrubbers for flue gas desulfurization and heat exchangers to recover waste heat at low temperatures in fossil fuel fired plants. The corrosion resistance of welded joints does not degrade in the as-welded condition. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength as well as fracture toughness. It also includes information on low and high temperature performance, and corrosion resistance. Filing Code: Ni-532. Producer or source: Mitsubishi Materials Corporation, Okegawa Plant.
