The liquid conventional and biogenic fuels are pre-evaporated in a specially developed evaporation reactor. The implementation was initially carried out by setting up a demonstrator with an output of 100 kW, which was scaled to 300 kW during the course of the project. The results achieved show that the bio-multi-fuel burner enables stable simultaneous combustion of the pre-vaporized liquid and gaseous bio-fuels with low pollutant emission levels. In their pure form or as admixture components, biogenic fuels have so far only been used in exceptional cases to provide industrial process heat.
The research results showed that gases and oils produced in industrial processes can be utilized as fuel and can be applied in both high-temperature and low-temperature applications. These include, for example, the use in melting furnaces, heating furnaces and heat treatment furnaces with an exhaust gas atmosphere. Which are typical furnaces applied in the iron, steel and light metal industry, or tunnel furnaces, firing chamber furnaces in the brickworks and ceramics industry. Other applications are drying plants and boiler firing systems, for example for media heating in the low-temperature range. In addition, small and medium-sized companies that operate a wide variety of boilers and drying plants in rural areas without a natural gas infrastructure in the lower output range could thus secure their energy supply with renewable fuels.
The bio-multi-fuel burner developed enables the simultaneous use of a large number of gaseous and liquid fuels of different compositions. This high fuel flexibility of the bio-multi-fuel burner can also contribute to the secure and develop local, previously unused biogenic fuel sources with a strongly fluctuating supply chain.
