What is the difference between thermal and coal power plant?
As a type of thermal power station, a coal-fired power station converts chemical energy stored in coal successively into thermal energy, mechanical energy and, finally, electrical energy. … Compared to a thermal power station burning other fuel types, coal specific fuel processing and ash disposal is required.
What is a steam power plant?
A steam power plant consists of a boiler, steam turbine and generator, and other auxiliaries. The boiler generates steam at high pressure and high temperature. The steam turbine converts the heat energy of steam into mechanical energy. The generator then converts the mechanical energy into electric power.
What are the advantages of thermal power plant?
Advantages of Thermal Power Plants
- Making Energy from Thermal Power plants is easy.
- The fuel used (coal) is cheap.
- Thermal Power Plant can be set up anywhere near fuel and water supply.
- It requires less space as compared to the hydroelectric power station.
What are the uses of thermal power plant?
A thermal power Plant / Station is used to convert heat energy to electric power / Energy for household and commercial applications. In the process of electric power generation, steam-operated turbines convert heat in to mechanical power and then finally electric power.
What is the thermal efficiency of steam power plant?
Efficiency. The efficiency of a conventional steam-electric power plant, defined as energy produced by the plant divided by the heating value of the fuel consumed by it, is typically 33 to 48%, limited as all heat engines are by the laws of thermodynamics (See: Carnot cycle).
What are the types of steam power plant?
Steam Turbines. Three basic types of steam turbine are used to generate power as a by-product of process or exhaust steamml: condensing, pass-out condensing, and back-pressure.
What is the disadvantage of thermal power plant?
Disadvantages of thermal power plant are:
The running cost of thermal power station is more as compared to hydro power station. It pollutes the atmosphere due to production of large amount of smoke and fumes. Maintenance cost is more. Skilled persons are required for erecting and maintaining the power station.
What is the disadvantage of thermal power?
Following are the disadvantages of thermal power plant:
As thermal power plants involve the production of large amounts of smoke and fumes, these affect the atmosphere. The overall efficiency of the power plant is low. The maintenance cost is expensive.
What are the disadvantages of thermal heating?
The main disadvantage is that the thermal oxidation operates at 800-900 C compared with 250-350 C for the catalytic alternative. The high operating temperature also means that more energy must be added to the process as a supplemental fuel, compared to a comparable catalytic process.
