Definition of open cycle gas turbine?

An open cycle gas turbine (OCGT) is a type of gas turbine that converts fuel energy into mechanical energy through a continuous process. In this system, air is drawn in, compressed, mixed with fuel, and combusted, generating high-temperature exhaust gases that drive a turbine. The exhaust gases are then released into the atmosphere, making the cycle "open." OCGTs are often used for peaking power plants due to their quick startup times and ability to meet fluctuating energy demands.
