What is the definition of combined cycle turbine technology?

A modern combined cycle gas turbine/ steam turbine power plant can reach almost 60% efficiency.

Rankine cycle is used in steam turbine

There are 3 ways to convert oil to electricity: 1. Conventional steam: oil is burned to heat water and steam, to turn the turbine 2. Combustion turbine: oil is burned under pressure to get hot exhaust gases 3. Combined-cycle technology: oil is firstly combusted using the combustion turbine meathod, then after the gases are recovered, they heat the water in a boiler and power a second turbine Hope this helps - Jack (http://edinburghjunction.webs.com)

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

The open cycle exausts the gases (produced by combustion) directly to atmosphere, sometimes the heat can be reclaimed to be utilised in a combined system (Rankine cycle added to gas cycle). Where as the closed cycle will reuse the gasses from the exaust instead.

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.

Gas turbine works on bryton cycle where as steam turbine works Rankine cycle. Construction, operation of a gas turbine are entirely different to steam turbine. Gas turbine has a compressor to compress the combustion air, a combustion chamber to burn the fuel and a turbine section to extract the work for burning fuel. Steam turbine is just has a turbine section to extract the work from steam.

in open cycle arrangement the exhaust coming out from turbine is rejected into the atmosphere. so the air enters to compressor goes to combustion chamber then to turbine and then rejected to atmosphere.

Your question is very Bad should you know the dearator in water cycle and turbine in steam cycle

In an open cycle gas turbine, the gases that are produced by combustion go directly into the atmosphere, though the heat produced can sometimes be reclaimed. In a closed cycle gas turbine, the gases produced are reused and are not emitted into the atmosphere.

A combined cycle is characteristic of a power producing engine or plant that employs more than one thermodynamic cycle. Heat engines are only able to use a portion of the energy their fuel generates (usually less than 50%). The remaining heat (e.g. hot exhaust fumes) from combustion is generally wasted. Combining two or more "cycles" such as the Brayton cycle and Rankine cycle results in improved overall efficiency. It can also work with the Otto, diesel, and Crower cycles which may allow it to be suited to automotive use. Aside from the Rankine cycle, the Stirling cycle could also be used to re-use waste heat in automotive or aeronautical applications, for the simple reason that there is less weight (water) to carry and that stirling engines or turbines can be made to operate with low temperature differences. In a combined cycle power plant (CCPP), or combined cycle gas turbine (CCGT) plant, a gas turbine generator generates electricity and the waste heat is used to make steam to generate additional electricity via a steam turbine; this last step enhances the efficiency of electricity generation. Most new gas power plants in North America and Europe are of this type. In a thermal power plant, high-temperature heat as input to the power plant, usually from burning of fuel, is converted to electricity as one of the outputs and low-temperature heat as another output. As a rule, in order to achieve high efficiency, the temperature difference between the input and output heat levels should be as high as possible (see Carnot efficiency). This is achieved by combining the Rankine (steam) and Brayton (gas) thermodynamic cycles. Such an arrangement used for marine propulsion is called Combined Gas (turbine) And Steam (turbine) (COGAS).

Inefficiencies in the compressor of a gas turbine cycle increase the back-work ratio and decrease the thermal efficiency of the gas turbine cycle, since they increase the compressor work.

Technology can pollute the water cycle.

A dynastic cycle is a cycle of dynasties.

1 cycle is the compressions and breaths combined.

"Dynastic cycle" is a Chinese political theory. By definition, it is the name for the cycle of the rise and fall of dynasties.

A simple-cycle gas turbine used for power generation has a thermal efficiency of about 34 percent. Since 1 kwh is theoretically equivalent to 3,415 Btu, the simple-cycle gas turbine has a fuel connsumption of: 3,415 / 0.34 = about 10,000 Btu/kwh. Given the heating value (i.e, heat of combustion) of a fuel, we can easily calculate the simple-cycle gas turbine fuel usage. For example, natural gas has a net heating value of about 21,500 Btu/pound. Thus, the natural gas consumption in a simple-cycle gas turbine would be: 10,000 / 21,500 = 0.47 pounds/kwh = 0.21 kg/kwh. As another example, a typical diesel oil has a net heating value of 130,000 Btu/gallon. Thus, the diesel oil consumption in a simple-cycle gas turbine would be: 10,000 / 130,000 = 0.077 gallon/kwh. (The gallon used just above is the U.S. gallon rather than the Imperial gallon) A combined-cycle gas turbine will have a higher thermal efficiency and, hence, lower fuel consumptions.

Gas turbine engines and airbreathing jet engines use the Brayton Cycle.

by increasing the turbine inlet gas temperature

Due to expansion of steam in turbine steam gets moist at 10% of moist rating steam is bleed out of turbine for reheating by flue gases coming from boiler thus forms a regenerative cycle.

Have you ever looked up the definition of cycle?
