Thermal Autoignition Temperatures for Hydrogen-air and Methane-air Mixtures.
J Fire Sciences 1988 6(5):348-355
The autoignition temperature and ignition delay times for hydrogen- air mixtures and methane-air mixtures as a function of concentration were measured in the U.S. Bureau of Mines 1.2-L ignitability furnace. The data show that the minimum autoignition temperature (mait) values obtained for hydrogen-air and methane-air mixtures are in excellent agreement with previously reported ait values of other researchers. There is also good agreement in the gas concentrations at which the mait's occurred.
