Résumé

Describes the 600-kW natural gas-fired combined heat and power (CHP) unit recently installed in London's Science Museum. The CHP unit is powered by a water-cooled gas engine that drives a generator. Heat is recovered from the engine water, exhaust gases and lubricating oil. The engine will use about 75% of the gas input to provide 600 kW of electricity output and 873 kW of heat output as 90 °C low-pressure hot water piped to radiators in toilets and staircases as well as two giant air-handling units that will provide air heating. In summer the heat generated will be piped to a 500-kW absorption chiller providing chilled water to cool the museum. The payback period is calculated at seven or eight years.
