Abstract

The results of comprehensive experimental studies on the environmental performance of various designs of existing refinery furnace gas burners in relation to air flow swirl are presented. Mathematical models of the influence of the degree of air flow swirl in swirl burners on the concentration of the formed nitrogen oxides and noise level generated during operation for the studied gas burners are obtained. The reasons for the increased emission of nitrogen oxides and the level of generated noise are established. Ecological advantages of GP-2 type swirl burners are demonstrated as the least toxic and quietest among examined burners. Practical recommendations for improving the environmental efficiency of the operation of swirl burners at refineries are given.
