Thermal Power Pant

The following is the correct order of energy conversion in thermal power plants

• Chemical energy – Mechanical energy – Electrical energy

• Mechanical energy – Chemical energy – Electrical energy

• Wind energy – Mechanical energy – Electrical energy

• Heat energy – Electrical energy – Mechanical energy

In thermal power plant, turbine is placed

• before boiler

• in between boiler and generator

• after generator

• any of the above

In the steam condensing power plants

• The amount of energy extracted per kg of steam is increased

• the steam, converted into water, can be re-circulated with the help of pump

• Both (A) and (B)

• None of the above
