High-Pressure Combustion Chamber

The high-pressure combustion chamber test bench enables the phenomenological investigation of flame stability limits, self-ignition and spray behaviour of various gaseous and liquid fuels. For this purpose, a universal interface is located at the centre of the chamber, on which mixing elements, nozzles and individual burners can be mounted.

The test bench essentially consists of a combustion chamber designed as a pressurised unit, a compressed air preheating system, a feed system for liquid, gaseous and vaporised fuels as well as measurement, control and regulation technology. Several modular segments with a high degree of optical accessibility also enable the investigation with detailed spatially and temporally resolved laser measurement techniques.

In addition to optical measurement technology, the use of precise exhaust gas and temperature measurement technology (NOx, CO, CHx, H2O) in the combustion chamber is possible in order to evaluate the effects of different fuel mixtures and injection variants on pollutant emissions.
