Limitations of the Carnot cycle for the operation of the steam power plant?
The Carnot cycle gives the theoretical maximum efficiency of an engine operating between two heat reservoirs. The Carnot cycle is an idealized engine cycle that is thermodynamically reversible. Real systems such as power plants are not reversible, and the entropy of a real material changes with temperature (which is not accounted for by the Carnot cycle). A steam power plant operates closer to a cycle known as the Rankine cycle.
What does a reactor do in a nuclear power plant?
The reactor in a nuclear power plant generates heat to flash water to steam, which spins turbines that generate electricity. This is not really any different, in terms of steam cycle1, than a fossil plant. Its just that the source of heat is nuclear fission of (usually) uranium-235 instead of the burning of coal, oil, or natural gas. ----------------------------------------------------------------------------------------------- 1Well, its a little bit different because the nuclear steam supply cycle runs best on a slightly lower pressure and temperature than a fossil fuel plant steam cycle does. Other than that, the steam and generating parts of a nuclear plant are very comparable to a fossil plant.
How is steam produced at a power plant?
By heating water
What is steam power plant function?
doing porno is good
Is steam power plant is internal combustion or external combustion engine?
A steam engine is an external combustion engine.
Does combined cycle power plant has a boiler?
No It has heat recovery steam generator
What are reasons for over speed tripping of steam turbine genarator in a combined cycle power plant?
wHAT??
What is the efficiency of thermal power plant?
A modern combined cycle gas turbine/ steam turbine power plant can reach almost 60% efficiency.

Describe the role of steam in a nuclear power plant?
In a nuclear power plant, steam is generated by heat produced from the nuclear fission reaction. This steam is used to spin turbines connected to generators, producing electricity. The steam is then condensed back into water and reused in a continuous cycle.
Why hydrazine is used in water and steam cycle of power plant?
It scavanges oxygen in water systems to prevent corrosion of piping.
Why you use condensor in the steam power plant?
The steam exiting the low pressure end of the turbine has to be condensed back to water in order to be pumped back at high pressure to the inlet of the steam raising units. The cycle is called the Rankine cycle and is common to all steam type power plants whether fossil fired or nuclear.
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 is geothermal power plant?
All geothermal power plants use steam to turn large turbines, which run electrical generators. This steam comes from steam produced from reservoirs of hot water found a couple of miles or more below the Earth's surface. There are three types of geothermal power plants: dry steam, flash steam, and binary cycle.
What is miniature steam power plant?
A miniature steam power plant is a place where willy wonka allowed his oompa loompas to stay on holidays.
