As discussed in the previous course, flue gas produced by power plant boilers contains water gases and particulates that can pollute the environment if released untreated. Using the flue gas desulfurization system (FGDS) open spray design has proven to substantially reduce sulfur dioxide in the flue gases emanating from a coal-fired plant

The Flue Gas Desulfurization, Open Spray, Part 1 training course explains how open spray FDGS design effectively reduces sulfur dioxide and provides flexibility in meeting its emission requirements. This online training course covers:

• Operating philosophy and purpose
• Flyash and lime modes
• Absorber tower and reaction tank
• Dampers and ductwork

This course is part of the Fundamental Aspects of Emission Controls training series.
