1. a combustion system that reduces discharged nitrous oxides, comprising:

  • One burner, has main combustion zone, again combustion zone and burnt zone;

    One main burner, this main burner is arranged in two layers of quadrangle tangential circle of four jiaos of one-tenth of burner, to provideAir and fuel are to main combustion zone;

    Burner again and again, this again burner arrangement on the wall of burner, become one deck surrounding each two become the circle of contactsTo provide air and fuel to combustion zone again;

    AndAirport at least one fire, is arranged on this combustion zone top again, is arranged on the wall of burner and becomes oneEach two of layer surrounding becomes the circle of contact, provides enough air via airport on this fire, forms this burnt zone;

    WhereinThe aspect ratio of this main combustion zone, again combustion zone and burnt zone is 1.2;

    1;

    2.5, this main combustion zone excess airRate 0.95 to 0.97, this is combustion zone excess air ratio 0.80 to 0.83 again, this burnt zone excess air ratio 1.10To 1.30;

    Wherein, this main combustion zone belongs to anoxic zone, and this belongs to more anoxic zone in combustion zone again, and this exists combustion zone againUnder micro-anoxia condition, produce a large amount of ionic hydrocarbons, the nitrogen oxide of those ionic hydrocarbons and this main combustion zone is anti-Should, reduction of nitrogen oxide is become to nitrogen.
