Discussion about Eliminating Gas Bypass in Wet Flue Gas Desulphurization System (Without GGH)

This paper introduces the objectives and working principles of the gas bypass in wet FGD projects, as well as domestic and oversea applications of gas bypass systems in FDG devices. Based on practical project, this paper conducts comprehensive analysis and compares whether to using gas bypass system in two 600 MW units from aspects in reliability, safety, economy, schedule, and configuration, etc. And feasibility configurations without gas bypass are presented to provide references for power plant selecting FGD schemes.
