Air Pollution Control Technology Fact Sheet

equipment (cold-side), however, reheating of the flue gas may be required, which significantly increases the operational costs. SCR is very cost-effective for natural gas fired units. Less catalyst is required since the waste gas stream has lower levels of NOx, sulfur, and PM. Combined-cycle natural gas turbines frequently use SCR

Flue-gas desulfurization - Wikipedia

For a typical coal-fired power station, flue-gas desulfurization (FGD) may remove 90 percent or more of the SO 2 in the flue gases. History. Methods of removing sulfur dioxide from boiler and furnace exhaust gases have been studied for over 150 years. Early ideas for flue gas desulfurization were established in England around 1850.

Flue-Gas Desulphurization - an overview | ScienceDirect Topics

Flue Gas Desulfurization (FGD) Processes. In many plants it is necessary to remove sulfur from the flue gases after the combustion process to meet environmental requirements. For this reason FGD is widely used to control emissions of sulfur dioxide (SO 2) and sulfur trioxide (SO 3) from plants burning coals with high sulfur contents. Various

Flue gas - Wikipedia

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived

Oxyfuel Combustion - an overview | ScienceDirect Topics

Flyash in the flue gas is collected in an ESP or baghouse, and flue gas desulfurization is employed to reduce sulfur oxide emissions. Compared with most other combustion technologies, oxy-fuel combustion has the inherent advantage of producing low NO x emissions since oxygen is used for combustion and the re-burning mechanism via flue gas recycle.

Phlogiston supporters: Air attracts phlogiston out of the charcoal, and burning stops when the air in the vessel is saturated with phlogiston. Critics also noted that when a metal burns, it forms a substance known as its calx, which weighs more than the metal, leading them to ask, Critics: How can the loss of phlogiston cause a gain

Boiler Combustion | CleanBoiler.org

Flue gas recirculation technology can be classified into two types; external or induced. External flue gas recirculation utilizes an external fan to recirculate the flue gases back into the flame. External piping routes the exhaust gases from the stack to the burner. A valve controls the recirculation rate, based on boiler

Particulates - Wikipedia

Particulates also known as atmospheric aerosol particles, atmospheric particulate matter, particulate matter (PM), or suspended particulate matter (SPM) are microscopic particles of solid or liquid matter suspended in the air.The term aerosol commonly refers to the particulate/air mixture, as opposed to the particulate matter alone. Sources of particulate matter can be natural or

Flue Gas - an overview | ScienceDirect Topics

The flue gas enters the lower part of the desulfurization absorption column under the action of the booster fan after being dusted by the dust collector. In the rising process, it comes into full contact with the falling limestone slurry sprayed by the spray. SO 2 in the flue gas is absorbed by the slurry and falls into the slurry pool at the bottom of the column.
