Hydrogen combustion

[boilerdoc]

Hi everybody,
I forgot to put a subject on my thread from yesterday.
So once again. Does anybody has experience with H2 fired industrial burners concerning NOx emissions? Is it possible to use waste hydrogen from a process with about 3% N2 and preheated combustion air without catalytic reduction of nitrous oxydes?

Q. Is the hydrogen used in a gasturbine? Hydrogen combustion
in a gasturbine will produce (only!) thermal NOx due to the higher adiabatic flame temperature: but no need for a deNOx measuures.

Hi Cees Jan,
the H2 is used in an industrial burner with preheated combustion air.It is clear that Nox formation results from high flame temperature and thermal oxydisation of airborne N2. Meanwhile I got the information that there are a few systems operating without catalytic flue gas processing within emission limits.
