Herningværket produces more heat from wood chipsadmin2019-06-06T09:08:54+02:00 Herningværket produces more heat from wood chipsArtelia is assisting Ørsted in the creation of a new flue gas condensation plant at Herningværket, to make the sustainable energy production deliver 10-20 % more district heating using the same fuel. When wood chips are burned at a biomass fuelled heating plant, they generate flue gas, which constitutes another resource in addition to the heat produced from the plant’s boilers. In the case of Herningværket, flue gas has a temperature of around 160-170 degrees when it passes through the chimney and herein lies the potential. The flue gas contains a lot of moisture and when that is condensed, cleaned and cooled, you can make use of the extra energy resource. Artelia is helping Ørsted to establish a complete facility for flue gas condensation at Herning-værket. When the facility is finished, the plant will have an increase in heating capacity equivalent to 40 megawatts. This means it can produce 10-20 % more district heating using the same amount of fuel. Buildings and machinery The task at Herningværket relies on two com-ponents. Artelia is the engineer for the construc-tion work and also provides machinery and processing expertise. For the machinery and process part, the task implies an overall layout for installing machines and connecting them to the existing plant. Artelia takes on the role of client consultant, where we are responsible for procuring the machine components, negotiating deals, managing contracts etc. Several sustainable heating plants On Zealand, Artelia is contributing to the creation of three biomass-fuelled heating plants, from empty field to the finished production facili-ties. The three clients are Maribo Varmeværk, Egedal Fjernvarme and SK Varme. SK Varme’s new plant in Halskov is straw fired and the project also involves a transmis-sion cable, which travels underneath Korsør harbour. Maribo and Egedal will have wood chip-fired plants and Artelia is also responsible for creating the adjacent district heating network for these.
