Electricity Generation - Cogeneration

Cogeneration

Cogeneration is the practice of using exhaust or extracted steam from a turbine for heating purposes, such as drying paper, distilling petroleum in a refinery or for building heat. Before central power stations were widely introduced it was common for industries, large hotels and commercial buildings to generate their own power and use low pressure exhaust steam for heating. This practice carried on for many years after central stations became common and is still in use in many industries.
