How do you reduce sulfur dioxide in coal fired power stations?
Using a method called flue gas desulphurisation which involves the addition of a calcium oxide. The calcium oxide basically absorbs the sulphur dioxide on its way out of the flues; economically, useful products are produced such as gypsum which can be used as plaster.
How is calcium carbonate used in coal fired power stations?
Limestone is used in a power station to neutralise the sulphur dioxide that is emitted. Carbon dioxide and carbon sulphate are both made!
What are the two chemical pollutants that are produced by coal fired power stations?
Most coal burned in power stations contains small amounts of the metal mercury. This metal is released and vaporized as the coal burns. Some coal, particularly lower-quality bituminous coal, contains nitrogen compounds. The nitrogen in this coal (and sometimes nitrogen from the air) combine with oxygen to produce various nitrogen oxides, some of which catalyze the formation of ozone in the lower atmosphere. Most modern coal-fired power stations have very efficient combustion, so they produce very little carbon monoxide, but some older plants produce significant (but still small) quantities. Carbon dioxide isn't universally considered a pollutant, but it is the main combustion product of coal. Some coal contains sulfur or sulfur compounds. These can be released by burning to produce sulfur dioxide, which reacts with water in the atmosphere to produce sulfurous and sulfuric acids, which are significant components of acid rain.
What power stations produce CO2?
Coal fired power plants,Petroleum power plants,
Why sulfur emissions from coal-fired power plants are considered an environmental problems?
causes acid rain

Are green house gases more or less than carbon dioxide?
Carbon Dioxide IS a 'greenhouse gas' ! There are still too many coal-fired power stations that are releasing tons of CO2 into the atmosphere !

Does coal burning power plants release radioactive waster?
While coal fired plants release particulates, carbon dioxide and sulfur dioxide as major pollutants they also release radioactive materials which were contained in the coal as aerosols.
What are the Disadvantages of coal fired power stations over nuclear powered stations?
The handling of many tons of fuel as opposed to a few truckloads of uranium, the production of carbon dioxide and sulfur dioxide, the disposal of many tons of ash, the mining of the coal which can be dangerous and has caused many accidents, and possibly the cost of the fuel relative to uranium though that depends on how easily the coal can be obtained.

Which is a waste problem of nuclear power that does not occur with coal-burning power plants?
The only waste from a nuclear power plant is spent fuel rods, which can be reprocessed. The waste from a coal fired plant is carbon dioxide, sulfur dioxide, mercury, ash, and soot.

What kind of steam engines are used in power stations?
Coal fired steam driven power stations are still in use
How could power stations reduce the amount of carbon dioxide they produce?
There are many ways to generate electricity. Methods that burn fossil fuels (coal, oil and natural gas) produce carbon dioxide. Methods using renewable energy do not. Nuclear power plants, although uranium in non-renewable, do not produce carbon dioxide. Power stations could be rebuilt to use different fuel sources. Biomass and biofuel will power a coal fired power station without emitting the carbon dioxide pollution.
