WebOct 14, 2003 · For hydrogen you can suppose a flame speed of about 10 fps when the mixture is stoichiometric reducing to zero (in a bell curve) at the LEL and UEL. If the hydrogen plus the air exceed the UEL mixture, you are pre-disposed to a flashback any time the velocity is less than the relevant flame speed. Because the UEL is so high (80% …
