Andritz to supply biomass boiler plant with fuel handling system to Vattenfall AB in Uppsala, Sweden
December 27, 2018
SWEDEN (News release) -- Andritz has received an order from the Swedish energy company Vattenfall AB to deliver a new biomass boiler plant with an external biomass handling system for their "Carpe Futurum" project. The plant will be located on Vattenfall's existing combined heat and power plant site in Uppsala, Sweden. The new plant will supply district heat to the Uppsala area and is also prepared for electricity production at a later stage. Start-up of the boiler is scheduled for the end of 2021.
The "Carpe Futurum" project is an important part of Vattenfall's goal of becoming CO2-neutral at their combined heat and power plant by 2030. Vattenfall delivers district heat to more than 90% of the houses in Uppsala, providing heat for about 150,000 people.
The Andritz scope of supply includes biomass receiving, handling and storage silos, a biomass-fired boiler with flue gas cleaning, and a flue gas condenser. The fuel handling equipment will be supplied with Andritz's own technology, which has been proven in several installations worldwide. The boiler is based on the Andritz EcoFluid bubbling fluidized bed design, which combines high efficiency with excellent environmental performance. The flue gas condenser after the boiler significantly increases the district heat output and, therefore, improves the plant efficiency. The fuel for this new plant will comprise different kinds of wood-based biomass, such as recycled wood, bark, wood chips, and sawdust. The plant will supply 110 MW of heat to the district heating network.
