Scrap wood powered wort boiler
I'm planning on making a scrap wood fueled wort boiler out of a metal milk jug and the blower out of a shop-vac. I throw away tons of scrap wood and pallets every day at work. I figure that instead of rotting away in some landfill, it could be boiling my wort.

It is roughly the same principle as a blast furnace for smelting iron ore, just on a smaller scale.

Is there any reason why you guys think this wouldn't work, or would advise against it?

Forgive my crude Paint drawing.

I like the design. Ive been thinking of something along those lines. I see so many pallet get throw out and I just think of boiling wort.

Do you think the smoke would affect the wort in any way? Can't see any problems other than that...

I'm sure it was how wort was boiled back in the day. Plus it's not like it's never been done before http://byo.com/feature/1005.html

Holy Crap, that is a lot of brew!

You have to be right though. I mean how else would they have heated the wort back then? I'm sure the smoke would only impart a minimal flavor in the beer as it is always going to be rising up around the kettle. I'm going to be burning mainly hardwood scraps, not pressure treated or anything, so it should be ok.

Has anyone else tried this?

Well, I know I'd shoot myself in the head if I had to listen to a shop vac for an hour.

Shop vac is a lotta air IMHO. I think you would have to gate it off or somehow throttle it back or you'd be blowin ash out the top??

I believe Kaiser(?) had photos of his trip to Germany where he visited a small village brewery that still used the original wood-heated brew-kettle. There's pics posted somewhere here on HBT.

Yeah I bet a small fan would be plenty of air....I just wonder how the milk can would hold up.

I wondering how the milk can will hold up myself. You may need a stand.

Agreed I would start by using a smaller fan.
