Sustainable development - Biomass boiler building for Hofor’s new power plant in Copenhagen

This project produced a biomass boiler building of 70 meters in height delivered by Valmet Technologies for Hofor’s electric and thermal power plant in Copenhagen, Denmark. The plant’s volume is 210,000 m3, and it is part of the City’s climate plan to become the first carbon-neutral capital in the world by 2025. This biomass-fired boiler plant can help reduce carbon emissions from energy production by 1.2 million tons per year.


The models of all plant-design disciplines perfectly matched

The project started in 2016 and is to be completed in 2020. Sweco designed the steel and shell structures for the boiler building. Their challenge was to design a building this large in the tight schedule given. Reference files to Tekla Structures (21.0) included the models of all plant-design disciplines, which enabled perfect matching of all the designs.

Reference data was imported to Tekla in IFC and DGN formats. The model was also utilized to schedule the project and follow up on the steel fabrication. Stairs, railings and connections were detailed using Sweco’s custom components. Tekla-Robot link was used to perform structural analysis and calculation. The client received both the drawings and the building information model. AVEVA PDMS software was used in plant design.
