Well due to the ever growing problem of global warming caused by pollutants in the air causing the green house effect (which destroys the protective atmosphere around Earth, and lets the harmful parts of the sun's ray onto Earth) We need to find an alternative to this, so a popular solution is Wind energy. Wind energy is clean through the fact no pollutants are released when the turbines spin/generates electricity.

∙ 13y agoTo obtain maximum efficiency from the steam turbine, the exhaust is held under vacuum, and the low pressure cool steam at the turbine LP stage outlet is condensed by external cooling water. This would be returned to the cooling source (cooling tower, lake, river, or ocean) at somewhere about 30C. This is too cool to do any useful work so it is just rejected to the atmosphere. Power plants can be designed so that the outlet water is warmer and this can then be used for district heating or industry, but this is only done where the requirement exists for the low quality heat. Obvously the first factor is siting the plant near to a large housing area or factory, and this is often undesirable for the people who live or work there.

Process of operation on geothermal power plant?
The process of operation a geothermal power plant involves moving heat up to the plant, heating water, and turning a steam turbine. This produces a renewable and clean form of electricity.
What is the electricity generated by magnetism?
Electricity produced by magnetism is called induced voltage. It is by induction, the passage of a magnetic field across a conductor, that a voltage will be induced ("caused" or "made to happen") in that conductor.
Is thermal energy the same as geothermal energy?
Not exactly. Thermal means heat, which can be captured from many places. We can generate electricity from ocean thermal plants, for example, using the difference in temperature between surface and deep water. Geothermal energy is another kind of thermal, from deep under the ground, where we use the heat to turn water into steam and power an electricity turbine.
Where does the water used to make steam in a power plant come from?
It is initially just normal mains water, but then it is purified by a demineralisation plant, so that water turning to steam does not leave deposits in the steam raising units or in the reactor in the case of a BWR. The steam is condensed to water after going through the turbine, and then recirculates, so the water makeup only has to replace loses due to leakage.
Why do power plants burn fossil fuels?
Power plants like Thermal Power Plant burn fossil fuels to heat water and then water turn into steam that creates enough pressure to run the turbines.Turbines rotate and electricity is formed.
What is the efficiency of thermal power plant?
A modern combined cycle gas turbine/ steam turbine power plant can reach almost 60% efficiency.
Should a power plant where the prime mover is a gas turbine be categorized as a thermal power plant?
No, a power plant that uses fossil fuels such as gas or coal, cannot be classified as a thermal power plant. A thermal power plant uses the heat from deep within the earth, combined with water to create steam, which then powers the turbines.
What is difference between structure of steam turbine in thermal power plant and nuclear power plant?
Nothing, except possibly size, but that would be because of different power rating of plant not different type of plant.
What is the difference between combined cycle and cogeneration?
In Cogeneration Plant : The generated steam in boiler is used for both power generation & process heating, thereby reducing the condenstion losses compared to thermal power plant. In combined cycle first is gas turbine , rather than wasting the flue gas from gas turbine, we are sending it into boiler and again generating steam for running steam turbine. Both the ways we are increasing the thermal efficiency of the plant
What spins the turbine of coal-burning power plant?
Steam spins the turbine of coal-burning power plant.
What is hotwell in thermal power plant?
In a pow4er house steam is expanded in turbine to get work from it . After expansion of steam it is condensed to reuse. The storage tank in which it is stored ,is called hotwell.
What is dearater in thermal power plant?
It removes the gases present in the steam,given by heaters.dearater is necessary otherwise the gases in steam will corrode the boiler and also affect the turbine.
How superheating of steam improves the efficiency of thermal power plant?
The amount of energy transferred from the steam is a function of the temperature difference between the input and output of the turbine. Also, superheating the steam ensures that there are no water molecules that can damage the turbine blades.
Why PRDS used in thermal power plant?
they work parallel to power generating turbines. The only difference between prds and turbine is that prds give only process steam by simply reducing the pressure of incoming steam while a turbine generates power out of that pressure reduction, and also give left out steam as process steam.
What is the steam of a power plant use for?
To drive a steam turbine which is coupled to an electrical generator
What is STG power plant?
STG stands for steam turbine generator which is one component of a power plant
What is difference between a geothermal and thermal power plant?
The steam turbine blades to turn creates steam.The steam engine, steam piston Myllng after the turn brings.+++They are both steam-engines. The turbine is purely rotative; the reciprocating steam-engine uses cylinders and pistons.
