Combined cycle gas turbine
Making Mission Possible - Delivering A Net-Zero Economy, published by the Energy Transitions Commission (ETC) in September 2020, suggests that combined cycle gas turbine (CCGT) is: ‘An assembly of heat engines that work in tandem from the same source of heat to convert it into mechanical energy driving electric generators.’
Best Available Techniques (BAT) Reference Document for Large Combustion Plants, Published by the European Union in 2017 defines a combined-cycle gas turbine as: ‘…a combustion plant where two thermodynamic cycles are used (i.e. Brayton and Rankine cycles). In a CCGT, heat from the flue-gas of a gas turbine (operating according to the Brayton cycle to produce electricity) is converted to useful energy in a heat recovery steam generator (HRSG), where it is used to generate steam, which then expands in a steam turbine (operating according to the Rankine cycle to produce additional electricity).’
Planning our electric future: a White Paper for secure, affordable and low-carbon electricity, Glossary, published by the Department of Energy & Climate Change on 14 July 2011, defines a Combined Cycle Gas Turbine (CCGT) as a: ‘A power station that generates electricity by means of a number of gas turbines whose exhaust is used to make steam to generate additional electricity via a steam turbine, thereby increasing the efficiency of the plant above open cycle gas turbines.’
