Burning velocity and NOx formation in the combustion of NH_3 mixed with H_2 at different air-fuel equivalence ratios and different H_2/NH_3 ratio were experimentally studied in this research. NH_3 burning velocity increased with increase of amount of H atom in the flame with the addition of H_2. Burning velocity of H_2/NH_3-air changed with the H_2/NH_3 ratio, and it seemed to be highest at the H_2/NH_3 of 0.67. The nitrogen in NH_3 converted to N_2 during the combustion. Small amount of NH_3 converted to NOx and its concentration increased with the increase of H_2/NH_3 ratio.
