How it works

Cogeneration process

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.

Features & Benefits

  1. Strong exhaust energy at high temperature and high fuel flexibility  enable GE gas turbines to be used in industrial cogeneration applications.

  2. GE E- and F-class gas turbines offer high availability and reliability in industrial cogeneration applications.

  3. For refineries, GE E-class gas turbines with the DLN combustion system operate with process gases with reduced emissions levels without water injection.

  4. For steel mills, GE E-class turbines use steel mill gases (blast furnace gas and coke oven gas) in a cogeneration configuration.

  5. GE gas turbine output and exhaust energy fit electricity and industrial steam demand.

  6. In an industrial complex for cogeneration, the modular design of GE gas turbines meets individual layout constraints.
