Design Requirements

Anti-corrosion coating in desulphurization flue of one wet flue gas desulfurization equipment (FGD) (model 1 and model 2) was designed and studied according to environmental and technical parameters of a coal-fired power plant. And relevant design requirements were confirmed. Application results showed that polyureas has wear and high temperature physical properties, so that it can be used in flue desulfurization equipment for anticorrosion. When the construction of a thickness of 2.0 mm, the high-temperature polyureas protective coating appearance smooth, EDM(electric discharge machining) 100% pass rate, adhesion 10.8 MPa, at 160 °C environment still had outstanding performance, that make sure it could reach its design life of the flue based on estimating the corrosion margin.

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 Flue-gas desulfurization (FGD) gypsum has occasionally been used as an additive to cement. Consequently, appropriate facilities are required to ensure the environmentally safe processing of FGD gypsum and the resulting cement material properties. Such facilities are yet to be developed because the amount of FGD gypsum used is still small when compared with the vast amounts of FGD gypsum generated. In this study, we analyze the effect of FGD gypsum addition on the physical properties, stabilization, and radon count of steam-cured mortar and compare its performance with air-cured mortar. Our results show that the steam-cured pozzolanic hydration products of ettringite and C-S-H promote the densification of the mortar structure, thereby resulting in nanopore size reduction and increased strength of FGD gypsum mortar subsequent to the steam-cured hydration process. Further, our environmental test results indicate that steam-cured pozzolanic materials composed of FGD gypsum are environmentally safer than air-cured cementitious materials.
