Cogeneration is the simultaneous production of electricity and thermal energy from a common fuel source. GE's gas turbines provide for cogeneration efficiency of ~80%.
With broad industrial experience, fuel flexibility, high exhaust energy-to-power ratio, exhaust temperature, and reliability, our gas turbines are an excellent fit for industrial and refinery cogenerations, providing electricity and high quantity process steam at high pressure. GE's E-Class gas turbines can operate with alternative fuels
, such as heavy fuels, steel mill gases, and syngas. GE's F-Class gas turbines can operate with fuels such as natural gas, light distillate, and syngas.
Fuel is burned in the gas turbine which drives a generator to generate electricity. High temperature gas turbine exhaust flow, with optional supplementary firing, feeds a heat recovery steam generator (HRSG). Steam is either extracted for industrial process usage or used in a steam turbine that drives a generator to generate electricity. Steam can be extracted from intermediate steam turbine stages for industrial processes or hot water production.
GE heavy duty gas turbines offer high fuel flexibility and high exhaust energy to generate a lot of steam at high pressure.
Strong exhaust energy at high temperature and high fuel flexibility enable GE gas turbines to be used in industrial cogeneration applications.
GE E- and F-class gas turbines offer high availability and reliability in industrial cogeneration applications.
For refineries, GE E-class gas turbines with the DLN combustion system operate with process gases with reduced emissions levels without water injection.
For steel mills, GE E-class turbines use steel mill gases (blast furnace gas and coke oven gas) in a cogeneration configuration.
GE gas turbine output and exhaust energy fit electricity and industrial steam demand.
In an industrial complex for cogeneration, the modular design of GE gas turbines meets individual layout constraints.
