Question

Analyze the thermal power plant carefully and list all burn out products which
are harm full for the environment. Give reasons for excessive pollution of the
thermal power plants. The ash produced in the thermal power plants will it used
for any useful purpose of it just goes as the land fill. Express your thoughts.

Expert Solution

Step 1

Thermal power plants are known to pump out a lot of greenhouse gases and ash, which are by-products of burning fossil fuels.

Carbon dioxide is one of the main gases that is released from the burning of fossil fuels and is known to be a greenhouse gas and a contributor to global warming. Out of all the gases released from a thermal power plant, carbon dioxide is the main one, and thermal power plants are one of the foremost contributors to the high carbon dioxide levels throughout the world.
Sulfur dioxide is also one of the gases that are released from power plants. Although it is theoretically not a greenhouse gas, it is known to have secondary effects on the atmosphere because it can affect the scattering of incoming sunlight, the formation of clouds, and precipitation patterns. In so many cases, it is considered as a secondary greenhouse gas. Sulfur dioxide forms sulphuric acid in the atmosphere. This gas can then return to Earth in the form of acid rain and impact various ecosystems. The level of sulfur dioxide released from thermal power plants is governed by the quantity of sulfur in the coal used. Thermal power plants are also the largest emitters of sulfur dioxide worldwide.
Nitrogen Oxide is also one of the gases that are released to the atmosphere by thermal power plants. Thermal power plants are also one of the biggest donors to the global nitrogen oxide levels in the atmosphere. Unlike nitrous oxides, nitrogen oxides are again not theoretically greenhouse gases, but they do have a secondary effect on the atmosphere. The visibility and respiratory health issues are also caused due to the presence of Nitrogen oxide, and they can also combine with other atmospheric gases and moisture to form acid rain and smog.
Ash often contains damaging particulate matter, as well as heavy metals. Ash can have numerous effects; it can get into waterways and soil wherever it falls and change the alkalinity of the soil/water. This can render the water undrinkable and the soil unusable for agricultural purposes. Ash and the particulate matter contained within are also a major cause of smog.
