The Hagedorn sawmill in North Rhine-Westphalia has six drying chambers, which are used to bring 400 m³ of sawn oak wood to a usable moisture content. Since 2014, the Hagedorn sawmill has been generating the electrical and thermal energy required for this with a wood gasifier from Spanner Re². Due to the increased energy requirements and the outstanding running times of the first energy system, the sawmill will be adding another wood gasifier from Re² in 2023.
Wood gasifier references from Spanner Re² convince sawmill owner 2014
The Hagedorn family had been thinking about generating energy from the chips for some time. When German subsidies for electricity generation from biomass were to be reduced, this provided the final impetus for the purchase of the wood gasifier in 2014 to produce energy by themselfes for their sawmill opertaions. Spanner Re² impressed with its numerous references, as the wood gasifiers have proven themselves and run without too much effort.
Generate additional electricity revenue with wood gasifiers from Re²
With the investment the sawmill produces a consistent source of electricity and heat. This doesn´t only save on the cost off electricity, but also generates a legal support of 5.4 Cent/kWh in. With a rated power of about 50 kWel as well as approximately 8,000 operating hours per year, the result is a 5-digit euro sum of money.
Remote access to wood gasifier via Smartphone
Kevin Hagedorn operates the wood gasifier and can easily control and regulate the process from a distance with his smartphone. “I need to access rarely, but always refill it. 350 hours was the longest non-interrupted operating time until now” says director Hubert Hagedorn. “For the service of the wood gasifier we invest less than 8 hours per month – for filter change, motor oil change and spark plug change.
2023 further wood gasifier from Re² installed in the sawmill
In 2023 Hagedorn expanded their business with a second wood gasifier from Re².
