Question

List two steps of energy conversions in
thermal power plants.
[CBSE 2015
the maior constituents of natura​

Answer 1

Answer:

In conventional (coal) thermal power plants chemical energy (in coa) is converted into heat energy, which in turn is converted into electrical energy. In a Thermal Power Plant, energy is extracted through coal ignition. Hence, chemical energy of coal is used as a fuel in Thermal Power Plants.

Answer 2

The energy conversions that take place in a coal fired power plant are as follows.

Chemical potential energy, in the form of coal (Step D) => Heat energy (Step C) => Kinetic energy or mechanical energy (Step B) => Electrical energy (Step A).

Every time energy is converted from one form into another a great amount of it is lost during the conversion. The less energy conversion steps, therefore, the more efficient the production of electricity becomes.

A major difference between a nuclear power station and a coal fired power station is the way heat energy is produced to heat the water. Describe the difference between a nuclear power station and a coal fired power station.
