COMBUSTION METHOD AND APPARATUS FOR NOX REDUCTION

摘要

Combustion method and apparatus for NO x reduction which are capable of achieving NO x reduction with the value of exhaust NO x under 10 ppm, as well as CO reduction at the same time. The combustion method for fulfilling NO x reduction and CO reduction by suppressing temperature of combustion gas derived from a burner comprises a NO x reduction step for suppressing combustion gas temperature in such a manner that suppression of NO x generation is preferred to reduction of exhaust CO value, thereby keeping NO x value not more than a specified value, and a CO reduction step for thereafter reducing exhaust CO value resulting from the NO x reduction step to not more than a specified value.
