      A weed or roofing torch puts out about 500,000 BTUs. You need to think a little bigger.

      These put out about 60 times as much, around 30 million BTUs, and a 30’ flame. The pilot light on a hot air balloon burner is a 12-18" flame.

      The burner cans weigh about 20 pounds, so a bit large to shoulder, but pretty easy to sling.

      They burn liquid propane, not vapor, so you’ll probably want a forklift tank rather than the usual 20# barbecue bottle.
