METHOD AND DEVICE FOR LOW NOX COMBUSTION

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for low NOx combustion capable of simultaneously realizing a reduction in NOx and and a reduction in CO to lower discharged NOx value to 10 ppm or below.

SOLUTION: This low NOx and low CO combustion method capable of realizing a reduction in NOx and a reduction in CO by controlling the temperature of combustion gas from a burner comprises a low NOx step for lowering NOx value to a specified value or below by suppressing the temperature of the combustion gas while preferring the suppression of generation of NOx over a reduction in exhausted CO value and a low CO step for lowering the exhausted CO value in the low NOx step to a specified value or below.
