Experimental investigation on the effect of double-burner configurations on the incineration of fumes - A natural gas case study

Burner configuration in a double burner system affects its performance. Generally, interference between burners degrades their performance and hence increases air pollution from incinerators or industrial burners. However, it has been found that there is a preferred interference that improves the performance of the burners. The selection of a burner configuration that gives the best performance has been found to depend on the equivalent ratio of the feed (Φ). A configuration of parallel burners is preferred in a premixed fuel lean case (Φ<1). However, a configuration of perpendicular burners is preferred for non-premixed diffusion flames. In the premixed fuel lean case, the difference of CO concentration in the flue gas between the worst and the best configurations has been found to be 34%. In the premixed fuel rich case, the difference of CO concentration reached 88%. For laminar diffusion flames, where no premixed air is used, the difference has been found to be 167% for CO and 116% for CH₄.
