4. What is thermal power plant?
 A thermal power plant is usually defined by the type of fuel used to
heat the water and create steam.
A fossil-fuel power plant is one that burns fossil fuels such as coal,
natural gas or petroleum (oil) to produce electricity.
 Fossil-fuel power plants are designed on a large scale for continuous
operation.

10. Air pollution and global warming
• carbon dioxide, a common part of the burning coal.
• Nitrogen oxides come from burning gas, coal, or other fossil fuels.
Sulfur Dioxide pollution comes mainly from the burning of coal or oil
in power plants or factories.
• Around the coal based power plants the ambient concentrations of
Sulphur dioxide of nitrogen and spm are high.
• The high amount of carbon dioxide emission from thermal power
plants contribute to global warming leading to climate change
significantly.
