Dear all
First of all, I lack knowledge of LEL and UEL. What I know, below LEL, or 100%LEL (5% by volume), methane is too little to burn, so a flame cannot happen. And above UEL% (15% by volume), the mixture is too rich to burn or explode.
At what concentration of methane does burner support proper combustion (good air-fuel ratio) and at what point the fuel become rich and can cause an explosion?
Thanks for your help.
