Experimental study of merged flames from multifire sources in propane and wood crib burners

This paper describes a series of experiments that were carried out to study merged flames that are created from multifire sources. A porous 15-cm(2) propane burner and a specially designed wood crib burner were operated at various heat-release rates. In the propane burner, temperature distribution was measured with thermocouples at different heights along the centerline. Product gases from the wood crib burner were captured by a hood to measure the total heat-release rate. The experiments provided measured heights of the merged flames, as well as a series of relationships between flame height and heat-release rate for multifire sources.
