摘　　要：In order to study the effect of oxygen-enriched combustion technology on the temperature field and NOX emission in the continuous heating furnace,this paper studies the oxygen-enriched combustion of a pushing steel continuous heating furnace in a domestic company.This study utilizes numerical simulation method,establishes themathematicalmodels of flow,combustion andNOX generation combustion process in the furnace and analyzes the heat transfer process and NOX generation in the furnace under different air oxygen content and different wind ratio.The research results show that with the increase of oxygen content in the air,the combustion temperature in the furnace rises significantly,and the emission concentration of NOX increases.Furthermore,the NOX emission concentration is related to the proportion of primary and secondary air.
