Combined cycle gas plants are a type of natural gas power plant used to generate electricity, consisting of a simple cycle gas plant in combination with a second steam engine that uses the Rankine cycle. The hot exhaust gases from the initial gas turbine are sent to the steam engine, and the heat from them is used to generate steam.
Integrated Gasification Combined Cycle (IGCC) An Integrated Gasification Combined Cycle ( IGCC) is a technology that aims to extract the maximum energy out of a fuel that is burnt.

CO 2 emissions from power plants using combined cycle technology are about 50 percent lower than most coal-fired plants. Emissions of NOx and SO 2 are 80 to 90 percent lower.
Combined cycle plant for power generation is a plant that converting the energy in natural gas/fuel into electrical power involves the creation of mechanical work which is then transformed into electric power by a generator. The term “combined cycle” referred to the multiple combination of thermodynamics cycle to generate electricity.

Basic combined cycle. One is the Joule or Brayton cycle which is a gas turbine cycle and the other is Rankine cycle which is a steam turbine cycle. The cycle 1-2-3-4-1 which is the gas turbine power plant cycle is the topping cycle. It depicts the heat and work transfer process taking place in high temperature region.
The thermal efficiency of today’s combined-cycle power plants are much higher than conventional steam power plants. For example, a combined-cycle power plant with the F-class gas turbine having firing temperatures between 1300 and 1400°C attains thermal efficiency of 55–57%.
The surface condenser is a critical component in the operation of a steam power plant. Condenser failures can result in forced outages and loss of generation capacity. TEi condensers represent an evolution of advanced technology, offering improved thermal efficiency and advanced mechanical design to reduce forced outages and increase availability.
The most common type of combined cycle power plant utilizes gas turbines and is called a combined cycle gas turbine (CCGT) plant. Because gas turbines have low efficiency in simple cycle operation, the output produced by the steam turbine accounts for about half of the CCGT plant output.
Combined cycle power plants integrate two thermal cycles, operating at a high- and low-temperature range, respectively, to yield higher plant efficiency and output than either cycle operating alone. Each cycle operates with separate working fluids and the two cycles are integrated by exchange of heat from the high-temperature (topping) cycle to the lower temperature (bottoming cycle).
As coal-fired power plants gradually become less sustainable, combined-cycle power plants offer an alternative for domestic power generation that is both cleaner and more efficient. Advances in hydraulic fracturing technology and the resulting shale gas boom have made natural gas the fuel of choice for an increasing number of private investors and consumers.
