This paper describes the results of an experimental study undertaken in an industrial regenerative ＇horseshoe＇-flow-type oil-fired furnace for the production of glass containers. The data reported include in-flame gas species concentrations of O-2, CO, CO2 and NOx, and gas temperatures, for one of the furnace operating conditions. The results reveal: a) in-flame peak temperatures of about 1690 degrees C; b) exhaust-gas temperatures of about 1520 degrees C; and c) exhaust levels of CO at 0.1%vol and NO2 at 580 ppm. The data presented are especially useful for evaluation and development of 3-D mathematical models.
