Abstract The purpose of this study is development of some parametric emission factors for gas flares using pilot-scale flare and investigation of the effect and interaction of important parameters on the emission factors. The considered parameters were flame Reynolds number, superheat steam-air flow rate and wind speed. Every variable was considered in four levels and the experiments were carried out two times. The results of 128 experiments showed that the average emission factors of CO 2, CO and NO x pollutants are 127.183, 0.731 and 0.074 lb/MMBtu (pound per Million British thermal unit), respectively. In addition, variance analysis of variables showed that the CO 2 and CO emission factors are significantly influenced by wind flow and NO x emission factor is influenced by superheat steam-air flow rate.
