Gas turbines convert fuel energy into mechanical or electrical power, in the latter case by connecting to electric generators. The underlying thermodynamic cycle, known as the Brayton Cycle, involves the compression of a gas medium (typically air), the addition of fuel energy through combustion or heat exchange, and the expansion of the hot compressed gas through a turbine, to convert the thermal energy into shaft power. In many instances the optimum choice for power generation is the use of a gas turbine fitted with a Heat Recovery Steam Generator (HRSG), which exploits the energy content of the exhaust gases from the gas turbine to generate steam by heat recovery. The generated steam may then be used as a heat exchange medium, or for further power production, as in “Combined Cycle” plants. At Energeco can boast an extensive experience in the design of combined-cycle or cogeneration plants, to support Investors in selecting an efficient and optimised engineering solution which best fits their needs.
