Predicting Burner Performance with Interchanged Fuel Gases

Temperature Dependence of Stability Limits of Burner Flames

“…In this instance, quenching takes place largely through dilution of the boundary layer by secondary air diffusing into it (6,21). In this instance, quenching takes place largely through dilution of the boundary layer by secondary air diffusing into it (6,21).…”

“…(6,9,IO). In practice, the initial temperatures of unburned mixtures flowing through hot ports are not readily evaluated.…”

Study of Fuel Composition Effects on Flashback Using a Confined Jet Flame Burner

“…Based on such a frame work, considerable experimental work has been conducted under various test conditions. Grumer et al conducted many flashback experiments on burner tubes for various fuel compositions using Lewis and Von Elbe's approach to explain the resulting data [5][6][7][8][9][10]. Bollinger, et al investigated effects of burner tip temperature on flashback of turbulent H2/O2 flames.…”

“…Fine performed experiments to determine the temperature and pressure effect on the critical velocity gradient [12][13][14]. Caffo et al and van Krevelen et al [15,16] developed some correlations using flashback data collected by Grumer et al for laminar flames in small tubes [5][6][7][8][9][10]. An additional correlation was proposed by Putnam et al and Ball et al [17,18] after investigating flashback for many different fuel compositions under laminar conditions and using small tube sizes.…”

“…Although previous works investigated turbulent flashback [11-14, 23, 26-28] their focus was not on the investigation of the effect of fuel composition whereas much of the previous work that directly examined the effect of fuel composition variation on flashback used smaller diameter tubes (<25 mm) where turbulent effects were less prevalent [5][6][7][8][9][10][15][16][17][18]. For several studies [8,11,14,28], the importance of bumer rim conditions such as tip temperature was noted, but these effects have not been studied systematically.…”
