Pyrolysis and combustion technologies

Pyrolysis (degassing and gasification) with combustion has become established as the best method for generating energy from biomass and biogenic residual fuels for plants with various outputs or sizes, especially for decentralized applications. The challenge with lower outputs is to design adapted system technologies that can be operated without great technical effort in a cost-effective and environmentally-friendly way in small businesses and residential buildings.

When it comes to developing combustion and gasification technologies for small and medium capacities, our experts in combustion and environmental protection have extensive know-how gained through many years of experience in this field. The best analytical and gas measurement techniques available on the market, normative approved test benches and programs for combustion calculations as well as flow simulations, such as SolidWorks, form the basis of the high-quality research work carried out by our scientists.

Combustion technologies include in particular small-scale firing systems in accordance with the first German ordinance on the implementation of the Federal Immission Control Act (BImSchV), whereby a distinction is made between individual room firing systems in accordance with DIN EN 13240, DIN EN 13229, DIN EN 15250, DIN EN 12815 and boilers in accordance with DIN EN 303-5. In addition, we develop special combustion technologies for specific industrial applications.

In the area of fuel pyrolysis (degassing and gasification), we develop technical solutions and technologies to produce specific qualities of fuel gas or mixtures thereof in order to efficiently operate gas engines and gas turbines, as well as fuel cells using biogenic and residual fuels. Fuel pyrolysis with the direct use of fuel gases is becoming increasingly common and is also a promising energy technology for the future due to the many ways of utilizing biogenic and residual fuels to generate energy. It also has numerous advantages over conventional combustion techniques when it comes to generating electricity on a decentralized basis. Our particular expertise in this area concerns pyrolysis as a primary method for avoiding dust and gaseous pollutant emissions, especially fine dusts, hydrogen halides (HCl, HF), nitrogen oxides NOx, sulfur dioxide, dibenzodioxins and dibenzofurans.
