LOW-NOX COMBUSTION METHOD, AND DEVICE THEREOF

摘要

PROBLEM TO BE SOLVED: To easily achieve lowness of NOx at less than 30ppm by the discharged NOx value.

SOLUTION: First lowness of NOx with a generated NOx value of 60ppm (as converted to 0%O2) by a low NOx burner 2, second lowness of NOx by recirculation of discharged gas from the low NOx burner 2 to a combustion reaction zone 6 formed by the low NOx burner, and third lowness of NOx by addition of water or steam to the combustion reaction zone 6 are combined with each other.
