Reference: Straw Fired District Heating Plant Midtlangeland Fjernvarme
Location: Midtlangeland, Denmark
Upgrade of the existing boiler house required changing the old steam-based boiler to a new Justsen hot water boiler. The project was implemented together with Tjæreborg Industri. Total contract value is reported to be around 25 million Danish kroner. Justsen boiler components were delivered from Brabrand to the site in Midtlangeland in two parts.
First part contained steel base, stoker, shredder and a rotary valve. The watercooled moving grate was shipped a few days later. The boiler is equipped with urea-based SNCR (selective non-catalytic reduction) de-NOx system to meet NOx requirements.
System Specification: 7.7 MW hot water boiler designed for district heating technology.
Fuel: Straw from wheat, barley, rapeseed, rye, oats and other origin.
Fuel Feed System: Stoker.
Justsen Boiler Type: Hot Water Boiler JUE-GVB.
