Parameter

4.6.2.8 gas turbine technology

An internal combustion engine system that converts fuel energy into mechanical power through three main components: a compressor (which draws in and pressurizes air), a combustion system (which mixes fuel with compressed air and burns it at temperatures over 1100°C), and a turbine (which extracts energy from the hot gas to drive the compressor and generate mechanical work).
Gas turbines are used widely in power generation (achieving 33–44% efficiency in simple cycle, over 60% in combined cycle), aviation (jet engines), and marine/industrial propulsion.
Modern gas turbines can achieve inlet temperatures up to 1400°C using advanced cooling and materials, and combined-cycle plants with heat recovery can reach overall efficiencies approaching 80%
