  • Patent number: 6823821
    Abstract: Combustion method and apparatus for NOx reduction are capable of easily achieving NOx reduction to an exhaust NOx value of 30 ppm or under. The combustion method is to perform in combination a first NOx reduction step for suppressing generated NOx value to 60 ppm or under (at 0% O2 in exhaust gas, dry basis) by a low NOx burner, a second NOx reduction step for recirculating exhaust gas of the low NOx burner to a burning reaction zone formed by the low NOx burner, and a third NOx reduction step for adding water or steam to the burning reaction zone.
    Type: Grant
