Question 3.
Other than thermal power plant, which power plants use thermal energy for power generation? In what different ways is the thermal energy obtained?
Answer:
1. Nuclear power plants: in nuclear power plants, the nuclear energy is obtained when uranium atoms are bombarded with neutrons. The uranium atoms break into smaller atoms through a process of fission, hence releasing nuclear energy. The nuclear energy obtained is converted into thermal energy. The kinetic energy of steam obtained through this is converted into kinetic energy of turbine which thus helps us obtain electrical energy.
2.Solar thermal power plant: Thermal energy is obtained from solar radiation in solar thermal power plants. Many reflectors reflect and concentrate solar radiation on absorbers. There, the solar energy is converted into thermal energy. The thermal energy obtained from solar radiation is used to drive the turbine which thus helps in the generation of electricity in solar thermal power plants.
