Flame Characteristics and Emissions in Flameless Combustion Under Gas Turbine Relevant Conditions

Abstract

Nomenclature d = inner diameter of the FLOX® nozzle, mm Da = Damkohler number dl = position of fuel nozzle with respect to air nozzle exit plane, mm f = focal length, mm k = rate coefficient NOx = oxides of nitrogen (NO and NO2) OH = OH chemiluminescence (electronically excited) Tad = global adiabatic flame temperature, K Tair = air preheat temperature, K v = velocity in air nozzle, ms 1 = air equivalence ratio = equivalence ratio
