What is Steam Power and Cogeneration Technology?


What is Cogeneration?

Also known as combined heat and power (CHP), cogeneration efficiently generates heat and electricity at the same time. This power and heat are then used in a process application. These systems can exceed 80% overall efficiency, which almost makes CHP very energy efficient.

How does Cogeneration Work?

A CHP system uses the exhaust energy from gas turbines to produce steam in a heat exchanger. This steam can be used in other applications without additional fuel consumption. Specifically, heat from a gas turbine is captured and then recycled to produce a stem, which is employed for other uses such as heating and cooling. 

What Are Some Benefits of Cogeneration?

Cogeneration uses only one fuel source to generate heat and electricity. This makes it much more efficient and cost effective than other systems using multiple fuel sources and processes. Cogeneration also eliminates waste, saves money and energy, and increases reliability and predictability.

Where and How is Cogeneration Used?

Cogeneration technology is used in variety of industrial settings, including:

  • Desalination power plants: CHP systems provide thermal energy for use in equipment that produces fresh water from seawater.
  • District heating power plants: Cogeneration systems provide heating and electricity for homes and facilities.
  • Combined cooling, heat, and power (CCHP) systems: Uses cogeneration plants and absorption chillers for excellent total fuel efficiency, as well as eliminating HCFC/CFC refrigerants and reducing air emissions.
