Waste Motor Oil / I need some ideas
« on: March 06, 2020, 08:51:57 pm »
Need some ideas...
I've been running waste oil in my oil furnace in the garage
It's a becket burner furnace. I'd either start it on diesel then switch to waste oil, or if I left waste oil in it I'd need to warm up the pump and burner to get it to start. It burned very well, no smoke or smell.
However, I started reading about how waste oil burns with a longer flame and may hit the back of the combustion chamber, so i looked inside and yes the combustion chamber was degraded badly at the back.
So, I removed the burner, and tossed the furnace, and built a boiler to install the burner in.
The boiler tank is 12 inches wide, 42 inches deep, and 72 inches high. The fire box inside is 8x8 inches and about 40 inches deep. Flues are 6 square tubes 1.5x1.5 from the rear of fire box up.
It is made from 1/8 inch plate and tubing.
Now the problems...
I need to figure out a combustion chamber of some kind, so the flame burns hotter and cleaner. It runs but the exhaust out chimney is either black from not enough air, or hazy and smelly.
Also, I need a way to heat the fuel line so that I don't have to manually warm it up to start it. I found online that beckett sells a line heater, but it seems small and not enough to keep it hot enough.
I tried the burner with and without the retention head, it doesn't seem to change anything.
Should I try to make a combustion chamber with fire clay? Steel? Ceramic wool? Not sure what would actually last.
