This plant will supply approximately 43 MW of heat to the district heating network in Aalborg. The efficiency is approximately 100%, and the energy produced will supply some 16,000 houses with electricity, and 30,000 houses with district heating.
With a combustion capacity of 37 tonnes waste an hour (9.2 MJ/kg), the Högdalen unit is characterized by flexibility. The plant is capable of burning municipal solid waste (MSW) and industrial waste – mainly refuse-derived fuel (RDF). B&W’s supply includes a furnace/boiler with economiser, a complete ash/slag system and a system for transporting fly ash from the boiler rear pass.
B&W supplied the complete incinerator with state-of-the-art Waste-to-Energy technology which included waste crane, feed chute, feed grate and five-section combustion grate, combustion air system, auxiliary burners, ash conveyors for slag and fly ash from the boiler hoppers, feed water pumps with controls.
The I/S REFA waste incineration plant in Nykøbing Falster, Denmark is jointly owned by 13 municipalities. The company collects and treats all kinds of waste from households and industries on the two islands of Lolland and Falster, a total of about 200,000 tons/year. The majority of the waste is either combusted or recycled.
B&W was selected to design a Vølund™ waste-to-energy (WtE) combustion system and boiler for Shenzhen Energy Environmental Engineering Co. The 5,600 tons per day plant is among the world’s largest and was completed in 2020.
This plant is installed at the cardboard factory Örebro Kartongbruk AB, situated in Örebro, Sweden. The fuel consists partly of wet and dry fractions of waste from the cardboard factory and partly of unsorted industrial waste including plastic, wood and a fraction of uncombustible material.
