what are the different types of air pollution produced by coal burning power station?

Question

plz explain them!!

Answer 1

It's not entirely possible to list every single component that may get into the environment. That's because coal consists of a wide variety of chemical compounds, which vary depending on what kind of coal you use... and also because different plants use different techniques to clean up their emissions. A coal plant in the US will put out a lot less nasty stuff than one in, say, China.

But anyway, the prime output of coal (or any kind of) combustion is carbon dioxide. This is a greenhouse gas, and contributes to global warming and the acidification of the oceans. In some plants, the CO2 is sequestered in the earth or collected for other purposes, but that's not the majority.

carbon dioxide is technically a product of the desired combustion reaction:
hydrocarbon + air = carbon dioxide + water + heat

But often you don't get complete combustion, and you either don't react all your hydrocarbons or you produce others. So you have residual things like fly ash. Fly ash can be collected and used to make things like bricks, but if it is not you get a nasty flying ash that hazes up the sky and gunks up your lungs.

And then there are the types of pollutants which are not part of the reaction, but come into the reactor along with the coal and come out with the carbon dioxide. That's things like oxides of nitrogen and sulfur dioxide. These guys acidify water, making acid rains. Then you have the weird trace elements in coal, which can include radioactive isotopes and just about anything you can imagine.

Answer 2

coals consist if carbon,nitrogen,sulfur,hydrogen and oxygen...
when you combust the coal it produces 1. carbon dioxide 2.sulfur dioxide 3. water 4. ash(small amount of sulfur and nitrogen)
1. carbon dioxide pollutes the air by decreasing the oxygen in the atmosphere and leading it to green house effect..
2. sulfur dioxide when mixed to the air it will produce acid rain that destroys life form because of its acidity content

i hope this could help....

Answer 3

properly there are gasses, like CO and CO2 and methane. There are solids, like little soot debris. there is sulfur, that could style sulfur oxides, and that i think of those are in acid rain. Nitrous oxides are additionally released. Mercury, cyanide, and different risky chemical compounds/factors are utilized in heavy production and interior the production of non-public electronics. Do your individual study in case you want a extra special explanation.
