Cyclusgasturbines

Cyclusgasturbines, also known as combined cycle gas turbines (CCGT), represent a highly efficient method of electricity generation. They combine two thermodynamic cycles to maximize the conversion of fuel energy into electrical power. The process begins with a gas turbine, similar to those used in aircraft engines, which burns natural gas or other fuels to produce hot, high-pressure exhaust gases. These gases then pass through a heat recovery steam generator (HRSG), where their residual heat is used to produce steam. This steam then drives a separate steam turbine, which in turn powers another generator. This two-stage process significantly increases overall efficiency compared to a simple cycle gas turbine operating alone. The primary advantage of CCGT plants is their fuel efficiency, leading to lower operating costs and reduced greenhouse gas emissions per unit of electricity produced. They can also offer flexibility in operation, with relatively quick startup and shutdown times, making them suitable for meeting fluctuating electricity demands. Commonly fueled by natural gas, CCGT technology is a cornerstone of modern power generation in many countries, contributing a substantial portion of the global electricity supply.
