A combined cycle power plant has multiple thermodynamic cycles. This increases efficiency.
For example, a gas turbine can be used to produce electricity, but only about 40% of the heat is actually converted in the process. 60% of the heat is lost, and in a single cycle plant would be considered waste heat. In a combined cycle plant, that waste heat could be used to drive a second, steam turbine to produce more electricity. In such a case, the efficiency could be increased from 40% to nearly 60%.
It is possible to go further. The waste heat from the combined cycle electric plant can be used to heat buildings, for instance, increasing overall efficiency to more than 65%. This is called Cogeneration.

Heat Rate in Natural gas based Combined Cycle Power Plant?
today rate of natural gas
Why hydrazine is used in water and steam cycle of power plant?
It scavanges oxygen in water systems to prevent corrosion of piping.
What is the Disadvantage Steam Power Plant?
Steam driven power plants necessarily lose heat , regardless of how the power is generated (oil, nuclear, geothermal, etc.), because only about 35% to 40% of the energy in the steam can be recovered to make power. This can be improved a little bit by having a secondary system, called a combined cycle system. It can also be improved by using waste heat to heat buildings. The limit, by combining all of these, seems to be a little less than 70% efficiency.
What kind of power plant is NAPOCOR?
NAPOCOR is not a power plant. It is a power company. It is the National Power Corporation of the Phillipines.
When was Tianwan Nuclear Power Plant created?
Tianwan Nuclear Power Plant was created in 2006.
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?

Where is India's first 140 MW integrated solar combined cycle power plant is planned?
Mathania, near Jodhpur, Rajasthan.
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.
This 140-mw iscc integrated solar combined cycle power plant with a solar thermal power generation technology will be indias first and among the worlds largest?
madhya pradesh
What are some different configurations of power stations?
Power Stations have the same principle of working and that is the use of combined cycles for several heating systems. The power stations can use a gas combined cycle or a solar cycle.
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
How much the maintenance in geothermal power plant operation?
50p
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.
Why do environmentalists oppose the operation of a nuclear power plant?
Because its is inexpensive and clean power
