fuel method

[Drenched_in_flame]

ok. my dad and i use a brake drum forge, and i was wondering if it would be more eficient to use rock coal rather than charcoal, could i possibly get some advise there?

Rock coal?????? Do you mean LUMP coal??? Using differnt fuels depend on alot: such as avaiablty, cleanyness, what your doing ( forge welding etc) So post some info please.

[m_brothers]

Yeah, what is rock coal???

Youjust need something that burns clean - the closer to 100% carbon the better. ( cept diamonds)

The best is coke, second is pure charcoal then comes mined coal and then low quality mined coal. You could use anything that burns basicly altho some material produce too much smoke or ash and dont get too hot. SOme people forge with corn or olive pips.
I use charcoal even tho it burns up rather quickly but it gets really hot.

Rock Coal=stone coal=sea coal = mineral coal. The first three names are old fashioned names for coal that is either mined from the ground or picked up off the beaches.

I use charcoal. I like charcoal. That being said, charcoal works better in a well insulated forge. If your brake drum isn't insulated you may get better results with blacksmith coal. And as was mentioned- cost, availability, neighbors all this and more should be used to determine the best fuel for you.

First thousand years of the iron age charcoal was the *only* fuel used; it burns hot and clean with little smoke and NO SULFUR and so has continued to be used as a forge fuel to this day.

If you are just starting out, real chunk charcoal is a lot easier to learn on than coal or coke.

Note: Briquettes are NOT charcoal they are a bunch of stuff mixed up with just a tad of charcoal in the mix and are not a very good forge fuel at all!

I have tried charcoal and found it very good if somewhat expensive. The coal I use burns VERY clean but you have to plan your fire a bit more and have it coking around the edges of the fire all the time, another thing to worry about when you are working. Also, you have to ensure you have a supply of coked coal to start the fire next time but that is as easy task.

Personally, I like the coal as it lasts longer and I find it easier to use, and cheaper

Does cheaper include the 150 mile trip to buy coal vs the 4.5 mile trip to buy charcoal? Or the 0 mile trip to make charcoal at home? Or do you have a local source?

In general I forge primarily with Propane and then coal and then charcoal; sifting the woodstove ashes to get it for free...

[rmcpb]

Cheaper includes the 20km trip to get a tonne from the mine for the cost of a few bags of charcoal here

If you have a significant trip for a supply make it a good haul or its not cheaper.
