Help! Flames out the chimney pipe!
Boiling last night in my not-quite legal shed and shooting a bunsen-burner type flame into the sky. I was glad my neighbors would not call the fire department. I have read about air-over fire, but I really don't want to get that high tech. I have a 4-foot cinder block/fire brick evaporator and a 7-8 foot vertical pipe (6"). I have air coming in under grates (about equal in volume to the 6" round). I burn pine, If I add a lot of wood, I get the chimney flames for 10-15 minutes. If I don't add enough wood, my boil gets pretty wimpy. I've tried reducing air intake, increasing air intake, leaving the top of the door slightly ajar --but no solution so far. Any thoughts for me?
