Hello

Here is a picture of my new homemade small oilburner forge.
I burns with dieseloil, and it consume about 1 liter/h
After five minutes its 1200 degrees:)

That is a cool set up!

I've wondered if it would be possible to use biodiesel for a forge fuel. Looks like you answered the question. Is it 1200 degrees Fahrenheit or Celsius? It would certainly have to get hotter than 1200 F. I assume that since you are in Sweden you mean Celsius.

Wow, that is great. Can you please post a simple drawing and instructions of how the burner is put operates. I would greatly appreciate it.

:cool: idea is the burner out of a central heating unit?

The burner is a simple oilburner from a centralheating equipment
in a ordinary detached house,
Yes its Celsius i mean.

I use 50mm thick cheramic fiber inside the forge.

I would think you can use any biofuel to the heat the forge, but you have to
adjust/suit the right burner for the right fuel.

Whats the benefits of oil burning over propane/natural gas?

did you need to do anything to the burner besides hook it up? whats the BTU rating on the burner?

Thanks
chris

I wonder if you could make one to run off of used motor oil. That would be super duper.

Kallsme'n, indeed, thank you. I have tried to Email you about this particular thing. I would be very interested in seeing the burner setup as well and any other particulars.

Thanks

Okey. i will post some more picture of the oilburner soon.

The benefits of an oil burner is that is much sheaper to heat upp, (here in sweden)
and there are much more safe than gas, minimum risks for explosions.

BTU rating ???? waths that, please explain for me.

The only thing i do to the burner before installing it was to change
the jet, ( i hope it

Here is a picture from inside the forge with the burner installed.

BTU, I guess it would be the heat rating.... maybe you guys go by kilowatts?

size of the burner?

ok, kilowatts, now i understand.
I will check the burner size tomorrow

Kallsme

Here comes some more pictures of the burner
I think the size of the burner is about 10kilowatts and consume from 1,8kg-3,0kg/h diseloil

Kallsme´n- That looks great!

Tyler- Though I wouldn't like to think of the byproducts, it can be done. I think waste fryer oil might be safer but I'm not sure. The following was posted on a metalcasting BB I visit. He used a 20# propane cylinder as the burner and it fire a crucible furnace made of a 55 gallon drum.....

He also posted this diagram:

''Here is a side "doodle":

@ = propane bottle
$ = exhaust/flame
* = oil

So, the bigger the pool/surface area of oil - the bigger/hotter the
exhaust..."

One thing I have found by looking around a bit is that his doodle left out a supply line that drips fuel where I added the X

Perhaps this link will explain BTU better than I can. Thank you for the pics of the unit. I will try and do the math on what your liter per hour fuel consumption rate is compared to the fuel rate consumption of one of my gas forges. Here in the US, LP ( Liquid Propane ) is sold by the gallon. Currently it is about $ 1.50 per gallon in my location. Diesel is roughly $ 2.50 per gallon ( but I must admit I haven't checked that price today ). LP fuel has a specific heat rating ( BTU ). The burner BTU rating will be dependent on oriface size and fuel pressure + the parent fuel rating as well. LP has a chart showing btu ratings based on oriface size ( and for all applications LP is regulated at 11 water column inches ). Gas forges of course will be used with an adjustable regulator and fuel pressure will be measured in pounds ( here in the US ). If I understand your oil burner correctly, the fuel ( diesel ) is pumped through an oriface ( injector ) at a given pound rate and the result is a predictable rating of heat. Thank you very much for the interest in showing us your shop equipment. All any of us really wants to do is get the heat we need to get the steel hot so we can forge it. :)

The oil is pumped through a main jet with high pressure, about 10bar
to get the oil in even smaller particels to burn better, and then mixed

Today i forgot the burner for a wile:( and the cheramik fiber was melt down inside the forge, the fiber should stand against 1400 degrees Celsius,
so it must have been over 1450degrees celsius.
That mean that you could use the forge to forgeweld.

The cost would be a lot cheaper if you used homemade bio-diesel.

I'd like to try that one day.

1liter diesel costs about 1,38 dollars here in Sweden, i think

1 BTU is about 3,4kilowatts, is that right:confused:

It takes about 15minutes to heat up 10kg skrapiron.

Kallsme´n

wow that heats up pretty quick, 10kg is about 22lbs, was that a big block of steel or a smaller round stock chunk.

My propane forge does well on round stock but on big blocks I really need to leave it in long soaking for the first heat.

yep 1 kilowatt is about 3414btu so your burner is around 34200 btu's
