We've been logging in some nasty interior cedar / hemlock stands the last while...some real nasty junk. Big wet piles full of dirt and sh*t, when you can drive up to them the tiger torch is the way to go...turn it on and stand back for 10 minutes. That blue cone dries a nice little pocket and away she goes. I like drip torches and find that they work for about 75% of the piles that we do - most are in the blocks and not on landings so lugging a 20lb bottle around isn't realistic."well, propane isnt ideal if your broadcast burning as im sure youll know, however, it is the preferred method for piles (IMO)."
Depends on the pile.
How its made and how dry things are.
If things are dryer then propane can be the cats meow.
In that study back in the seventies on several national forests they found that the drip torch was like a pocket on a shirt filled with sliced bread.
Meow to boot. The drip torch got the most done when burning conditions were averaged.
However; the drip torch does not go Pllooooocccchhhhh.
I thought powdered Tide was used? We had people mixing something, along with packets to make it into a more politically correct named stuff than Napalm. The lowest people in the caste system mixed it because that was a very nasty job. Fumes and all. I had enough seniority to escape that duty. They baggied it up and we packed it out to get fires going in piles--Eastern WA dry.Anybody use a mixture of liquid dish soap and gasoline for burning piles?
I've used dry soap but liquid seems to work better. The soap is just a surfactant so I imagine you could tailor it to suit your individual needs. We used to use liquid Joy and Av Gas to burn out the inside of Parathion drums. Sometimes we'd have contests to see who could get the most chain explosions and distance on the empty drums....aaahhhh the good old days. Anybody know what the statute of limitations is on stuff like that?I thought powdered Tide was used?

Scale matters obviously and my employeer doesn't pay me to stand around ....16,000 hand piles - no - maybe a 1/5th of that (machined piled)....most by drip torch....difficult landing piles ...where you stuff the torch in ...a dozen."...........turn it on and stand back for 10 minutes........."
On the district I just retired from last fall they had over 16,000 hand piles and just a hundred or so landing piles.
Spending a minute (on average) to lite a hand pile is too much.
The economics of 10+ minutes on a landing pile is fine. Bulk (size matters) discount.
However, we couldn't waste that amount of time on all those hand piles.
there are some places that use broadcast units for site prep, as i have worked on sites in no. Idaho (mainly). however, it has been for industry in my experience. flaming helitorches ruleAnd broadcast burning....whats that? We haven't lite a block up full scale since the early 90's....too much liability (ie: over achievment - although it was ok when the forest service let them go...). Its all mechanical site prep and piling for us now.
