Use of biomass for energy
As a leading company in the local production of energy, we have had many years of experience in the construction and operation of facilities that use biomass for energy purposes.

Our most recent facilities partly involve the use of untreated wood, i.e. residual forestry wood and landscape conservation wood, whilst in the medium term we are planning to use fuel wood from short-rotation plants. Under the German Clean Air Act, the firing system where these fuels are used must ensure that no pollution occurs even when the wood has a high water content. For economic and environmental reasons we want to build such plants reasonably close to the actual wood crops.

Depending on the size of a plant, we use a range of different firing techniques. If the thermal output is high, we prefer firing systems with circulating or atmospheric fluidised beds, whereas with smaller units we rely on grate furnaces.
Our existing biomass-fired cogeneration plants are largely based on the efficient combination of heat and power generation. This is where we burn used wood in categories AI – AIV. As fractions AIII and AIV are contaminated, our focus has been particularly on the combustion process and on flue gas purification. We therefore obtained approval for our facilities under the 17th Ordinance Implementing the Federal Immission Control Act. To prevent corrosion, the heating surfaces in the boiler need to be arranged in a certain way.
