Abstract:  
In the present paper, experimental and numerical investigation of a laboratory oil furnace have been done to study the effect of inlet air swirl angle on temperature and generating of pollutant CO and NO. The Concentration of pollutant CO and NO on the centerline of the furnace have been measured using gas analyzer. The numerical results are in good agreement with experimental data. The results show that the effect of vane swirl angle on the pollutant emission is significant and an optimum vane swirl angle can cause enhancement of thermal efficiency and reduction in pollutant emission. Increasing vane angle from 0 to 75 degree caused to first increase temperature and pollutant NO to a maximum value and then decreases them. Also, the results show that very large and small vane swirl angles cause to increase the concentration of CO outlet of the furnace and reduction of thermal efficiency. According to the results obtained in this study, the vane swirl angle of inlet air in the furnace can be adjusted to optimize pollutant generation and operation of furnace in desirable condition
