In order to study the combustion product NOx emissions of hydrocarbon fuel

a jet stirred combustion reactor (JSCR) experimental system was built and validated preliminarily. Then

kerosene RP-3 combustion NOx emission was tested using the experimental system under the conditions of pressures in jet stirred combustion reactor of 2×105Pa and 3×105Pa

inlet temperature of 650K

and equivalence ratios of 0.5 to 1.2. The study results show that when equivalence ratio of 0.5 to 1.2

the amount of kerosene combustion NOx emission firstly increases with the growing equivalence ratio and reaches the maximum value in the vicinity of the equivalent ratio of 0.95

and decreases subsequently; the amount of kerosene combustion NOx emission increases with the pressure rise. The jet stirred combustion reactor can be used as a verification test rig for combustion products of hydrocarbon fuels.
