The process of combustion is probably the longest standing natural as well as man-made process that converts combustible fossil and biofuels into thermal energy. This is, in fact, the energy conversion process in which chemical energy is being converted to thermal energy. A Thermal power plant is a power plant where steam is used to drive a steam turbine. This turbine is connected to an electrical generator. After this, the water is condensed and may be used again.
Some of the advantages of thermal energy are listed below.
- Important renewable sources such as solar heat, in which the source of energy is intermittent.
- It’s easy to handle and non-combustible.
- Waste heat is often a result of the thermodynamic inefficiency of thermal energy recovery processes.
- Thermal energy generated by fission processes can be recovered by different types of nuclear reactors, providing nuclear heat at a different temperature level that can be used for electrical or different nonelectrical purposes.
- Heat exchangers can be avoided.
