2×600MW new construction design of Flue Gas Desulphurization projiect In Easten Yunnan
Abstract
This design according to the given power of Easten Yunnan manufactory flue gas content 、position and dust removal and desulfurization requirements, combined with the flue gas desulfurization and dust removal technology situation of a set of flue gas desulfurization denitration system.
The major work for this design:Introduces several flue gas desulfurization technologies, chooses proper FGD process for this project paring merits and drawbacks of several major dust removal and flue gas desulfurization technologies. Finally, we applied the wet limestone-gypsum flue gas desulfurization process.
This design is to introduce the system of dust removal and desulfurization process of each subsystem and equipment layout. As for the FGD system, mainly introduces the process and facility arrangement of subsystems in FGD system, and they are respectively the system of limestone slurry preparation, gypsum treatment system, adsorption system, system of flue gas and wastewater treatment system. At the end of this design, it makes prehensive analysis of the whole system designed , and makes some engineering budgetary as well as some simple economic and technical analysis.
Keywords: wet limestone - gypsum and method, flue gas desulfurization and denitration main equipment
