[0016] Please refer to Figure 1 , an oxygen-rich recovery and combustion support system for a nitrogen generator, including a gas storage assembly. The gas storage assembly includes a nitrogen generator air buffer tank 1 and a four-way pipe 11. The four sets of interfaces of the four-way pipe 11 are respectively a first air inlet, a second air inlet, a first air outlet, and a second air outlet. The air outlets of two groups of nitrogen generator air buffer tanks 1 are both connected to a group of second seamless steel pipes 2. The air outlet of the second seamless steel pipe 2 is connected to a first valve 12. The air outlets of two groups of first valves 12 are respectively connected to the first air inlet and the second air inlet of the four-way pipe 11. The first air outlet of the four-way pipe 11 is connected to a third valve 15. A recovery assembly is placed outside the third valve 15. The air inlet of the nitrogen generator air buffer tank 1 is connected to the oxygen discharge port of the nitrogen generator. At this time, the oxygen-rich gas generated by the nitrogen generator is input into the nitrogen generator air buffer tank 1 for temporary storage. The recovery assembly includes a first seamless steel pipe 16 and a blower 17. The outer side wall of the first seamless steel pipe 16 is evenly provided with air outlets. The outer side of the air extraction pipe of the blower 17 is connected to a third seamless steel pipe 21. The air inlet of the third seamless steel pipe 21 is connected to the air outlet of the first seamless steel pipe 16. The air outlets of the third valves 15 in two groups of gas storage assemblies are both connected to a fourth seamless steel pipe 22.

Connect the air outlet of the blower 17 to the boiler air inlet. At this time, open the first valve 12 and the third valve 15. When the blower 17 works, the oxygen-rich gas in the nitrogen generator air buffer tank 1 will be input into the boiler along the four-way pipe 11, the fourth seamless steel pipe 22, the first seamless steel pipe 16 and the third seamless steel pipe 21 for oxygen-enriched combustion support, thereby improving the thermal efficiency of the boiler, reducing the flue gas temperature and soot, and thus achieving the purpose of energy conservation and emission reduction.
