Coal-Fired Power Plants

Coal is fired in the boiler to generate heat. Alternatives fuels i.e., pet coke, etc. can also be used as fuel. The hot flue gases containing fly ash is passed through a baghouse to separate the flyash before allowing the flue gases into the atmosphere through the stack.

​

Flue gas which is a mixture of many gases is obtained as the byproduct of the combustion process. These gases are released into the atmosphere which is the root cause of many diseases such as asthma, lung cancer, heart attacks which indirectly leads to early death of living beings. The gases evolved during combustion mainly are Nitrogen dioxide, Carbon dioxide, Sulfur dioxide, water vapor and traces of oxygen.
