Title:

COMBUSTOR FOR FUEL COMBUSTION AND COMBUSTION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2021/136218

Kind Code:

A1

Abstract:

Disclosed are a combustor for fuel combustion and a combustion method therefor. The combustor comprises a primary oxidant-fuel delivery assembly, a secondary oxidant delivery assembly, and a tertiary oxidant delivery assembly. The secondary oxidant delivery assembly and the tertiary oxidant delivery assembly are provided on the same side of the primary oxidant-fuel delivery assembly, and the secondary oxidant delivery assembly is located between the tertiary oxidant delivery assembly and the primary oxidant-fuel delivery assembly. The present invention combines the staged combustion and dilution combustion technologies, such that the combustor has a wide flame adjusting range, realizing adjustment of the flame combustion position, flame speed range, flame local atmosphere and flame length, effectively reducing the generation of NOx, and also achieving high heat transfer efficiency.
