Selection of Site for Thermal Power Plant

LIST DOWN THE FACTORS TO BE CONSIDERED FOR SELECTION OF SITE FOR THERMAL POWER PLANT:

Availability of coal:

•         A thermal plant of 400M, capacity requires nearly 6000 tons of coal every day.

•         Power plant should be located near coal mines.

Ash Disposal Facilities:

• Ash comes out in hot condition and handling is difficult.

The ash can be disposed into sea or river.

Water Availability :

•           Water consumption is more as feed water into boiler, condenser and for ash disposal.

•           Water is required for drinking purpose.

•           Hence plant should be located near water source.

Transport Facility :

Public Problems:

• The plant should be far away from residential area to avoid nuisance from smoke, fly ash and noise.

Nature of Land :

•           Many power plants have failed due to weak foundations.

•           Land (soil) should have good bearing capacity to withstand dead load of plant.

Explain about the pollution caused by Thermal Power Plant (Steam Power Plant):

•         Main pollutants from thermal plants are SO₂, CO₂, CO as minute particles such as fly ash.

•         SO₂ causes suffocation, irritation to throat and eyes and respiratory for people. It destroys crop.

•         CO is a poisonous gas.

•           Dust particles cause respiratory troubles like cough, cold, sneezing etc.,

Thermal Pollution:

•         Thermal plants produce 40 million kJ of heat to the environment through condenser water and exhaust gases.

•         Thermal pollution of atmosphere can be reduced using the low grade energy exhausted steam.

Noise Pollution:

•         The sources of noise in a power plant are turbo alternators, fans and power transformers.

•           Sound proofing can be done to reduce the noise.
