Waste Oil Burner Project

I have had some interest
in this waste oil burner stove I made to heat water which can be used for
many purposes.
Its design is very simple, I started with the leftover shell from a
60 gal Electric hot water tank that i cut a section from to make a snow
plow blade for my riding lawn tractor (see pics) ,
The tank had a concave bottom so while cutting the shell it was flipped
around and welded back on. The opposite end was also removed to shorten
the shell to a more manageable size. A chimney hole was cut in and a short
stack with a 6" dia was welded on for an exhaust and a small fitting to
fit the nozzle through was welded in place. When the Front bell was
off I cut a door into it and added some rudimentary hinges and some spacers
to the existing holes for a fresh air source.
The shell the had some anchors welded inside the circumference to it
to help retain the refractory material, then was lined with ceramic cloth
to allow for expansion and contraction of the refractory and shell
from the hot/cold cycles. The refractory was obtained from a local boiler
repair shop and unfortunately is one of the more expensive aspects of this
project but was a necessity as i wanted to be able to have this stove indoors
and not have a shell temp of 1800°+ F to burn one self on.. Before
lining the shell with refractory i cut a couple of holes for the necessary
plumbing and a form was made for the inside diameter to retain the refractory.
I had to cut some cheap laminate material to go between the anchors to cover
the ceramic cloth insulation from completely collapsing while tamping in the
refractory.
Tamping in the refractory was an adventure all in itself, but once
done it looked pretty sharp. If you choose to duplicate my efforts you should
consult the supplier for specific instruction on how to apply the refractory
as different brands will have different instructions.
After the refractory was set and heated up a bit to cure I
fitted the inside of the tank with 50 feet of 1/2" copper tubing (the
length of which I have determined is not enough) and plumbed the ends to
the outside of the shell.
I am still deciding on how much storage water to use, I have another
50 gal hot water tank that had rusted a pinhole out and I braised it up, Brass
is more then adequate as I don't intend to run any pressure beyond 20 psi
if I decide to seal the system.
For circulation i am running a 1/25 HP Taco radiant heating circulation
pump, so far with only the 50 ft of copper its more then enough, as a matter
of fact to regulate the temps I have a gate valve before the stove to slow
the flow down so its got time to pickup the heat. Hence the determination
of not enough copper tube.
The nozzle and associated hardware I'll explain in more detail on the Atomizer page (sounds so high tech doesn't it?)
And at the request of a
friend that I put a picture of a naked chick on my page.. Here it is!
