This paper reports the results of an experimental investigation of emissions from an impinging flame to a flat cold surface. This study pertains to the fuel rich premixed flame issuing from a 8-mm diameter nozzle burner. The effects of burner to plate spacing, equivalence ratio and Reynolds numbers on the flame structure and emission are investigated. The flame structure is characterized by temperature measurement. The axial temperature profiles show that it is strongly dependent on the distance between the burner and cold surface. The temperature in the radial direction declines sharply after certain distance from the center of the plate which is also seen to depend on the separation distance. It has been found out that the CO level increases for separation distance greater than 12 nozzle diameter for all Reynolds number which may be attributed to the excess entrainment of air leading to the dilution of mixture. However, the CO level also increases with increase in equivalence ratio for same separation distance. The NO level decreases with increase in equivalence ratio and Reynolds number. The separation distance of 12 nozzle diameter case gives higher NO level for all Reynolds number. The CO2 level increases with equivalence ratio for all Reynolds number. It is believed that these experimental data will be useful for designing and developing rapid heating devices. 相似文献
