For hydrogen burning in air at 1 atmosphere the Adiabatic Flame temperature is 2,400 K or 2127 C. When a flame loses heat to the environment, or is diluted with an inert material that has to be heated ...

The design of the test benches therefore differs in key respects: The air used for combustion is often heated electrically in order to reach real combustor inlet temperatures of the gas turbine type ...

The arrangement of the jets results in a pronounced recirculation zobe in the combustion chamber, which means that fuel, air and recirculated burnt gas are intensively mixed before combustion ...
