Coal combustion is the leading source of US sulfur dioxide emissions. Nitrogen oxides, key contributors to ground-level ozone (smog) and respiratory illnesses. Particulate matter (soot), which produces haze and can cause chronic bronchitis, aggravated asthma, and premature death (both sulfur dioxide and nitrogen oxides transform into particulates in the atmosphere).

Assessments on SGG and WSGG spectral models .

Coal combustion processes usually involve high levels of soot, which interferes in the radiation mechanism. For WSGG models the influence of soot in the radiative characteristics of the medium can be modeled by adding extra absorption and weighting coefficients to the formulation [ 5 ].

How Does a Coal Power Plant Work? - Bright Hub .

Coal combustion in the boiler requires air. Around 1.6 million cubic meter of air in an hour is delivered by air fans into the furnace. The ash produced from this combustion is around 200,000 tons per year. Electrostatic precipitators capture almost all of this ash without dispersing this to the atmosphere.

Fossil fuel - Simple English Wikipedia, the free .

Fossil fuels are fuels that come from old life forms that decomposed over a long period of time. The three most important fossil fuels are coal, petroleum, and natural gas.. Oil and gas are hydrocarbons (molecules that have only hydrogen and carbon in them). Coal is mostly carbon.These fuels are called fossil fuels because they are dug up from underground. ...

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

When coal is combusted in air it burns in a two step process. In the first step gases are driven out of the coal structure leaving behind a carbon char that burns in the second step. These chars play a critical role in combustion in that they must burn up in the reaction zone of the furnace or be carried out of the furnace as unburnt carbon in fly ash.
