Flue Gas & Emissions Analyzers | Nova Gas | Portable

A flue gas analyzer will enable you to measure the concentrations of various gases and adjust burners on a boiler to help achieve optimal combustion. Efficient combustion also reduces emission of pollutants such as nitric oxide (NO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and particulate matter.

NOx - Wikipedia

In atmospheric chemistry, NO x is a generic term for the nitrogen oxides that are most relevant for air pollution, namely nitric oxide (NO) and nitrogen dioxide (NO 2 ). These gases contribute to the formation of smog and acid rain, as well as affecting tropospheric ozone.. NO x gases are usually produced from the reaction among nitrogen and oxygen during combustion of fuels, such as

5 Environmental Effects and Tradeoffs of Biofuels

5. Environmental Effects and Tradeoffs of Biofuels. Petroleum extraction, transport, refining, and combustion have many known negative environmental effects, including disruption of sensitive ecological habitats and high greenhouse-gas (GHG) emissions.Biofuels, too, have their environmental costs (NRC, 2003, 2010a), but displacing petroleum-based fuels with biofuels can reduce the nation's

Flue gas desulphurization detailed process

Feb 16, 2015 · Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from exhaust flue gases of fossil- fuel power plants, and from the emissions of other sulphur oxide emitting processes. 8. It is a control device that absorbs and react using the alkaline reagent to produce a solid compound. 9.

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.
