I've had a brainstorm :).
As per usual, since I really have no idea about what I'm doing, it's a potentially dangerous brainstorm :(.
The garage is getting a little cool to be working out there this time of year & the old wood stove ain't what she used to be. Neither is the old wood. However, I can get my hands on a good burner that came off my parents old hot air furness that the heat exchanger rusted out on (Metal Content :)) after 30 years (& it wasn't new when they got it).
So, I've got the burner but I need to fabricate (Welding Content :)) a fire box/ heat exchanger, something that hopefully won't destroy the garage the first time I turn my back.
I was thinking of something involving a 50 Gal. drum or old hot water heater for the box, but I have no idea about the best way to move the heat out of it. Wrap it with big springs? Big sheet metal fins? Cut holes in the box & stick pipes through it? Blow air at it with one of those little suction-cup 12V fans from J.C. Whitney?
Rather than blowing myself up trying to re-invent the wheel I'd prefer to work from an already tested design. Anyone know of any designs or general design info available on the net? I've tried Google but didn't find anything really pertaining to what I'm looking for.
Also, does anyone know what would be involved in trying to burn waste oil in one of these burners? I realize I'd need a good filter, but will a jet designed for fuel oil work with waste oil?
Any & all input appreaciated!
Thanks,
Howard.
