An experimental investigation of high temperature air combustion was conducted in terms of the effect of the distance between the fuel and air nozzles on NO_x emission at different preheated temperatures and oxygen concentrations of the oxidizer in the configuration of cylindrical furnace. Highly preheated oxidizer was injected in the furnace through an oxidizer nozzle positioned at the center of the base of the cylindrical furnace. Propane was injected through three different sets of fuel nozzles, one set working at a time. As a result, the emission of NO_x decreased with the distance between the fuel nozzles and the oxidizer nozzle. At lower preheating temperatures and lower O_2 concentrations of the oxidizer, the emission of NO_x tends to become lower. The scaling law including the effect of recirculation in cylindrical furnace is proposed.
