Mercury Speciation in Coal Combustion and

1995-12-14·Coal combustion and gasification are an anthropogenic source of mercury emission to the atmosphere. Effectively minimizing the emission and understanding the atmospheric fate and transport of mercury require knowledge of its speciation in flue gases. Hg0(g) is the thermodynamically stable form in the highest temperature regions of combustors and gasifiers.

What Do Scrubbers Do in Smoke Stacks? | Sciencing

The resulting chemical reaction produces a synthetic form of the mineral gypsum, which can be adapted for use in concrete or drywall. This can be done in a few different ways. In a wet scrubber, the untreated exhaust is sent through a spray chamber where fine water droplets knock down the harmful particulates.

Coal Gasification | HowStuffWorks

2009-6-2·The heart of a coal-fired power plant is a boiler, in which coal is burned by combustion to turn water into steam. The following equation shows what burning coal looks like chemically: C + O 2–> CO 2. Coal isn’t made of pure carbon, but of carbon bound to many other elements. Still, coal’s carbon

Acid Gas/SO2 Controls – Institute of Clean Air

Scrubber systems rely on a chemical reaction with a sorbent to remove a wide range of pollutants, including sulfur dioxide (SO2), acid gases, and air toxics, from flue gases. When used to remove or “scrub” SO2 from the flue gas, these devices are commonly called flue gas desulfurization (FGD) or scrubber systems.
