Hi everybody,
does anyone has experience with hydrogene fired industrial burners? Is it possible to use waste H2 with about 3% N2 and preheated air without any catalytic deNox unit to stay within acceptable emissions concerning nitrous oxydes?

RE: Hi everybody, does anyone has expe

Yes.
With the precisely correct fuel/air mixture only air is needed for environmentally friendly combustion of hydrogen.  If the air is clean, the hydrogen pure, and the F/A mixture precisely controlled to maintain the combustion temp at all points below 2200 deg F,  water vapor and heat are the only products of combustion.

The greatest challenge is safely collecting, storing, and handling hydrogen and the prevention of a hydrogen explosion at ambient temp/atmospheric pressure. Hydrogen leaks from fittings will present a combustible mixture in the atmosphere. Expect rapid combustion in the event of the slighest spark from an electric switch or static electric discharge to a mobile human.
