Experimental study of merged flames from multifire sources in propane and wood crib burners
This paper reports results from a series of experiments that used propane and a wood crib in order to study merged flames from multifire sources. Burners with various heat-release rates were placed in arrays with various separation distances. The temperature distribution with height for propane experiments and the total heat-release rate for the wood crib experiments were measured. The heights of the merged flames were recorded. From the data a series of relationships between flame height and heat-release rate of multifire sources were obtained. The main conclusions are listed below. (1) For the propane experiments, temperature always increases with height initially, and then it decreases. Higher heat-release rates result in higher temperatures at the same height. (2) Increasing the separation distance for wood crib burners and multifire sources enhances combustion efficiency. (3) The relationship between the dimensionless flame height and the dimensionless heat-release rate with separation distance from 10 to 30 mm for propane and from 15 to 50 mm is the same as that with no separation distance.
