Abstract

Et system og fremgangsmåte for reduksjon av NOx - utslipp fra en gassturbin, hvor luft forsynes til gassdrivstofflinjen for delvis forblanding med gassdrivstoffet slik at forbrenningskammertemperaturen og flammelengden reduseres og derved NOx - utslippene reduseres.A system and method for reducing NOx emissions from a gas turbine, where air is supplied to the gas fuel line for partial premixing with the gas fuel so that the combustion chamber temperature and flame length are reduced, thereby reducing the NOx emissions.
