Summary:Cogeneration is one of the most cost-effective ways of supplying thermal and electric energy to process industries. A major reason for this is cogeneration's fuel efficiency: a given plant's efficiency can exceed 70% while a conventional electric power plant rarely exceeds 35%. Because the high simple-cycle efficiency of diesel engines results in less heat in the exhaust gas, diesel cogeneration plants can be used when an industrial processing plant has low steam-process requirements in relation to its electric power needs. Although diesel cogeneration is being utilized more often, a boiler/steam-turbine turbine cycle is still the preferred choice for cogeneration in many industrial applications. A 3rd type of cogeneration plant, the gas-turbine/heat recovery steam generator, is used when suitable fuels, such as natural gas and distillate fuels, are economically available.
