According to the superheated steam boiler system with the double low-nitrogen combustion systems, the double low-nitrogen combustion systems are arranged at the front end of the boiler, so that heat supply in unit time is improved; and moreover, a recirculation smoke pipe of the double-low-nitrogen combustion system is communicated with a smoke exhaust pipe at the rear end of the boiler, so that the recirculation combustion of smoke is realized, and the emission of nitrogen oxides is reduced. 本实用新型提供了一种具有双低氮燃烧系统的过热蒸汽锅炉系统，在锅炉的前端设置了双低氮燃烧系统，提高了单位时间内的热量供给；并且，双低氮燃烧系统的再循环烟管从锅炉的后端的排烟管连通出来，实现了烟气的再循环燃烧，降低了氮氧化物排放量。
