With today's rising power demands, geothermal power plants are attractive options for their cheap, environmentally-friendly energy production.
In coal thermal power plant, the steam is produced in high pressure in the steam boiler due to burning of fuel (pulverized coal) in boiler furnaces. This steam is further supper heated in a superheater. This superheated steam then enters into the turbine and rotates the turbine blades. The turbine is mechanically so coupled with alternator that its rotor will rotate with the rotation of

The thermal power plant uses oil, coal or gas while nuclear plant uses nuclear fuel. Nuclear Fuel energy is released by nuclear Fission Chain reaction in the core of a reactor. 1 kg of Uranium U 235 can produce as much energy equal to 3086 ton of coal or 136 m 3 of fuel oil.
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming.There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet
Nuclear power plant generates electrical energy using heat energy and Uranium-235 is used as a fuel, to produce that heat. Why Nuclear Power Plant is Invented? The depletion of the non-renewable energy resources forces the scientist of the world to find a new source of energy which can fulfill the requirement of the electricity demand of the world.
Biomass is a renewable source of energy, derived from burning animal and plant waste. Almost all industries (see extensive list), including agriculture, forestry, colleges/universities, municipalities, hotels, resorts, sports venues, hospitals and correctional facilities, produce waste that can be converted to heat and electricity.. A September 2017 report by the U.S. Energy Information

The draught is one of the most essential systems of the thermal power plant which support the required quantity of air for combustion and removes the burnt products from the system. To move the ait through the fuel bed and to produce a flow of hot gases through the boiler economiser, preheater and chimney require a difference of pressure.
There are many advantages of water tube boiler due to which these types of boiler are essentially used in large thermal power plant. 1) Larger heating surface can be achieved by using more numbers of water tubes.
14 Advantages and Disadvantages of Coal. December 16, Biomass technologies can be incorporated into existing coal facilities, allowing for a dual fuel source in the same power plant. This allows for coal to be used, but in lesser amounts, and that can help to reduce the amount of carbon dioxide and ash that gets produced from the burning
