The invention belongs to the field of industrial furnace combustion and flue gas emission, and particularly relates to a low NOx combustion system for a combined heating furnace and a control method of the low NOx combustion system. According to the system and the control method, through technological means of selecting a nitrogen oxide burner, adopting fractional combustion, high-temperature denitration in the furnace, low-temperature catalytic denitration outside the furnace and the like, thus production of nitrogen oxide in each stage of the combustion process is effectively controlled, supernet emission of the flue gas nitrogen oxide is realized, and finally, the amount of the nitrogen oxide is controlled at 50 mg/Nm<3> or below, even 20 mg/Nm<3> or below. The whole system is simple instructure composition, cannot bring the big change to existing heating furnace systems, and can be used on new or existing heating furnaces, the adaptability is high.
