Almost every time I've used the BGE lately I light it with one of the electrical starters, close the lid and wait for the temp to get about where I want it. Problem is when I open it back up these Hellish flames rise up from the charcoal and out around the dome singeing the hair off my arms and usually scaring the poop out of me. I can understand that these are probably flamable gases collecting in the egg and then pretty much exploding upward when I open the dome and introduce more oxygen to the mix. Seems like it has just started doing this recently and I'm a little baffled. I've been using Royal Oak lump. Any ideas why this is happening or how to stop it?
