Vattenfall Jordbro recycled wood fueled power plant in Sweden

Vattenfall Jordbro is a customer-specific combined heat and power plant that produces heat and electricity from 100% biofuel in Sweden. Valmet’s*) full-scope delivery included not only a boiler island, but also a turbine and flue gas cleaning system with fabric filters.

The Jordbro plant is Vattenfall’s second largest district heating plant in Sweden. The boiler has a total capacity of 64 MW, 43 MW of heat and 20 MW of electricity. It is fueled by recycled wood, consisting of waste from the construction industry, but can also use other fuels. This allows Jordbro to adjust the fuel mix according to fuel availability and price. This is something that benefits both the consumer and society, and was underlined by Vattenfall’s Nordic Director Torbjörn Wahlborg at the opening ceremony: “The Jordbro plant is a good example of our commitment to renewable energy, while at the same time, it ensures stable and competitive heat deliveries.”

The boiler at Jordbro has a unique design in the way it burns recycled wood chips and has an empty pass to cool the flue gas before the superheaters. The flue gas is continuously monitored. Emissions are extremely low thanks to the advanced combustion technology and the flue gas cleaning with fabric filters, which add lime and activated carbon to achieve the desired results.

With 31 employees, the Jordbro power plant delivers heat to around 33,000 houses and domestic electricity to about 6,500 homes.
