Flame speeds were determined for methane-air, propane-air, and ethylene-air mixtures at -73 degrees C and for methane-air mixtures at -132 degrees C. The data extend the curves of maximum flame speed against initial mixture temperature previously established for the range from room temperature to 344 degrees C.
