I have just put a secondary air intake on my gas bottle/oildrum insulated woodburner. The first thing I have noticed is less smoke and higher temperatures on the boiler plate. I think my other problem was insufficient primary air flow, caused by having a 4" steel chimney, but only a 2" primary intake.
