Chalk Point, Dickerson and Morgantown Wet Flue Gas Desulfurization Systems
GenOn Energy, Inc.
Houston, Texas
Overview
Babcock & Wilcox (B&W) supplied wet flue gas desulfurization (FGD) equipment to provide sulfur dioxide (SO2) removal efficiency of 98% of total gas flow. This design features a combination of components to provide a high level of reliability and removal efficiencies. These include a milling system, absorber towers, trays, spray headers, nozzles, mist eliminators, wash headers and forced oxidation.
