Combined cycle technology allows a power plant to generate 50 percent more electricity from its fuel than it could with a single-cycle power system. Here''s how it works: In a two-on-one combined cycle system, two combustion turbine generators work in conjunction with two heat-recovery steam generators and a steam turbine generator. In the
The combustion (gas) turbines being installed in many of today''s natural-gas-fueled power plants are complex machines, but they basically involve three main sections: The compressor, which draws air into the engine,
Large Sized Gas Turbine: These turbines generates power more than 50 MW. They are operated at a pressure ratio of 35:1 and a very high temperature of about 13-15°C. Aviation: The gas turbines are widely employed in the aircraft field to drive air compressors in turbo-jets and turbo-propeller engines. These engines are operated at a
The disadvantages of a gas turbine power plant are given as follows −. The overall efficiency of a gas turbine power plant is very low, about 20%, because the exhaust gases from the turbine contain sufficient heat. The temperature of the combustion chamber is very high (about 1700 °C). Hence, its life is comparatively reduced.
Working Principle of a Thermal Plant. The working fluid is water and steam. This is called feed water and steam cycle. The ideal Thermodynamic Cycle to which the operation of a Thermal Power Station closely resembles is the RANKINE CYCLE. In a steam boiler, the water is heated up by burning the fuel in the air in the furnace, and the
A gas turbine is a mechanical device that harnesses the energy of pressurized gas, typically air, to generate power. It operates by compressing incoming air, mixing it with fuel, igniting the mixture, and then allowing the high-speed exhaust gases to drive a turbine. This technology finds extensive use in aircraft engines, power plants,

A gas-fired power plant is a type of fossil fuel power station in which chemical energy stored in natural gas, which is mainly methane, is converted successively into: thermal energy, mechanical energy and, finally, electrical energy.Although they cannot exceed the Carnot cycle limit for conversion of heat energy into useful work, the excess heat, ie the
A gas turbine is a combustion engine at the heart of a power plant that can convert natural gas or other liquid fuels to mechanical energy. This energy then drives a generator that
The compressor used in gas turbine power plant is generally of type The air is drawn by the compressor from the atmosphere via the filter. The filter removes the dust from air. The rotary blades of the compressor push the air between stationary blades and raise the pressure. Thus air at high pressure is available at the output of the compressor.
A gas turbine, gas turbine engine, or also known by its old name internal combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power
These gases expand and drive the turbine''s blades as they pass through. Turbine work: As the hot gases flow through the turbine, their high-pressure energy is converted into mechanical work. The turbine blades are connected to a shaft, and as the gases push against these blades, they cause the shaft to rotate.
This gas turbine is not working, so it depends on the pressure of the atmosphere, so any type of force can be used to improve specific plant production. Once the pressure is applied to the turbines, the size of the components used in them can be reduced.

The closed cycle gas turbine works on the principle of Joule''s or Brayton''s cycle. In this turbine, the gas is compressed isentropically and then passed into the heating chamber. The compressor generally used is of the rotary type. The compressed air is heated with the help of some external source and then made to flow over the turbine blades.

A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy. On land, when used to make electricity the most common type is called a combined cycle gas turbine ( CCGT) plant, which is a kind of gas-fired power plant.
Although the operations of a gas turbine are complex, there are three essential parts: the compressor, the combustion system, and the turbine. The compressor works by pulling air into the engine, which is then pressurized and fed into the combustion chamber at up to several hundreds of miles per hour. The combustion system uses fuel injectors
Working of Open cycle gas turbine. The starting motor is used to initially start the compressor. The compressor then intakes fresh air and compresses it to a higher pressure. At the same time, the temperature of the air also increases. This compressed air is then passed to the combustion chamber.
The resulting. hot gas is allowed to expand through a turbine to perform work. 7.1 Introduction. As the principle of the gas turbine, a working gas (air) is compressed by a. compressor and heated
