Cogeneration supports sustainability goals

摘要

In the town of Orebro, 124 miles (200 km) to the west of Stockholm, Sweden, the tall chimney of E.ON's heating and power station is visible from a distance. White grey water vapor often billows out of the chimney from the biggest boiler, which is fired by bio fuels and heats the water for the district heating network and provides steam for the electrical production. District heating is a common method of heating for property in Scandinavia. Large boilers in the power station heat hot water, which is pumped around in a submerged pipe network to properties where heat exchangers transfer the heat to the buildings' own waterborne heating systems. The properties are residential apartment buildings, office buildings, and detached houses, and in Orebro, there is also a historic castle, parts of which date back to the 1300s.
