Introduction to FGD Gypsum. FGD Gypsum is a unique synthetic product derived from flue gas desulfurization (FGD) systems at electric power plants. Sulfur dioxide emission control systems used by coal-fired power plants remove sulfur from combustion gases using "scrubbers." One particular type of scrubber that uses lime or limestone reagent (i.e ...
11.16 Gypsum Manufacturing 11.16.1 Process Description1-2 Gypsum is calcium sulfate dihydrate (CaSO4 2H2O), a white or gray naturally occurring mineral. Raw gypsum ore is processed into a variety of products such as a portland cement additive, soil conditioner, industrial and building plasters, and gypsum wallboard. To produce plasters or
An electrostatic precipitator (ESP) is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.. In contrast to wet scrubbers, which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and ...
FGD materials can replace the natural gypsum that must be added to the final product to control the setting of concrete [EPRI 1999]. Currently, over 55% of U.S. portland cement plants use one or more of these byproducts to produce clinker or cement. Fly Ash Fly ash is the fine, powder-like material collected by the particulate matter control ...

Jan 06, 2019 Electrostatic precipitators are ubiquitous nowadays in thermal power plants due to ever-increasing concern about environmental pollution. Electrostatic precipitator uses the high-intensity electric field to ionise the dust particles in the air stream and then the dust particles are collected by oppositely charged collectors (electrodes). The dust particles, once collected are
