Hi, I'm considering what the effect of having mixed fuel gases would have, say for example a mixture of methane and propane. From the graph the max flammable concentration of methane would be 61% when present with 39% oxygen.

If we assume for a moment that propane has the same profile as methane then in a 50:50 mix of methane:propane then would a mixture of 61% fuel mix and 39% oxygen still be the maximum flammable concentration or does it depend on the individual concentration of each of the fuel gases which in this scenario would be 30.5% each of methane and propane. I'm guessing it would depend on the total concentration of the fuel mix but I'd like confirmation to be on the safe side.
