banjo burner power loss

[excaptn]

I have been using my classic banjo burner for 2 years and the last two brews it seems like I have lost power or BTU's after about 45 min into my boil. Not sure whats going on as I still have propane in the tank... for anyone from mountain state it kinda is acting like I am getting vapor lock.... any ideas oh what could be happening?

Yeah, your tank is freezing up. If you can get your hands on a 40lb tank, that won't happen anymore. The only thing I can think of is to keep it closer to the burner and try to trap some of the heat with some aluminum flashing or something.

I usually try to keep my tank as far from the burner as possible. I don't want to blow up... and I am a clutz. Pretty much I need to keep my tank warmer to prevent this...without causing a fire?

Use a big container and some hot water to keep it from freezing.

i also keep my tank in a bucket of warm water. this eliminates the freezing issue.

Or wrap it with Flexwatt Heat Tape and some blankets. The 11" tape produces 20 watts per foot, so you should be able to get 40 to 50 watts on a cylinder. That should keep'r flowing.
