Abstract

This study examines the types of hydrogen leaks that can support combustion. Hydrogen, methane, and propane diffusion flames on round burners and leaky compression fittings were observed. Measurements included limits of quenching and blowoff for round burners with diameters of 0.006-3.175 mm. The measured mass flow rates at the quenching limits were found to be generally independent of burner diameter. In terms of mass flow rate, hydrogen had the lowest quenching limit and the highest blowoff limit of the fuels considered. The quenching limits for hydrogen diffusion flames on round burners with thick walls were found to be higher than for thin walls. The minimum mass flow rate of hydrogen that can support combustion from a leaking compression fitting was found to be independent of pressure and about an order of magnitude lower than the corresponding methane and propane flow rates. The implications for fire safety are discussed.
