Abstract

Flue gas recirculation is considered to be one of the most promising and cost-effective NOx reduction strategies for combustion systems. Therefore, it has great scientific and practical significances to investigate the flue gas recirculation process. Fluent was used to perform a numerical flue gas recirculation simulation on natural gas combustion in a burner, revealing the relationship between NOx emission and circulation ratio, circulation temperature, and circulation locations. The following conclusions were drawn: the NOx generated with gas recirculation on is less than when there is no gas recirculation; the lower the gas circulation temperature, the less the NOx; when the circulation is 25%, the NOx generated is low; less NOx is generated if the gas is firstly mixed with the air before combustion.
