Multi-Fuel-Burner

The combination of lean, premixed combustion concepts with carbon-free (hydrogen, ammonia) and also synthetic carbon-neutral fuels harbours enormous potential for reducing greenhouse gas emissions in many areas of application. However, before the combination of combustion concept and fuel can be utilised in aviation, for example, the associated risks must be investigated. The primary concerns pertain to the potential for flashback of the flame, which has the capacity to inflict damage or even result in the destruction of the combustion system.

The investigation of these flashbacks is conducted on the multi-fuel-burner, where under defined flow and temperature conditions, originally liquid (in pre-evaporated form) fuels and combustible gases can be mixed with air and burned.The induction, quantification and optical analysis of flame flashbacks near the wall is facilitated by an automated test bench control system.
