v0.31:Fuel
| This article is about an older version of DF. |
- (Disambiguation: In Dwarf Fortress, Template:L is not the same as "coal" - see that article if desired.)
Fuel, refined coal, and just coal are three in-game terms that refer the same thing, any unit of charcoal or coke, the two fuels used to power high-temperature industries, namely metalworking, glassworking, and pottery. One unit of either of these fuels is required for every task at a conventional (non-magma) Template:L, Template:L, Template:L, or Template:L. Magma versions of these facilities do not need fuel, and in fact cannot use conventional fuel to power them if their magma sources fail. Refined coal is also needed as part of the pig iron and steel creation process (see below).
Although both "charcoal" and "coke" are simply listed as such when viewed in the game with the k, they are found under the "bars" section of the z-stocks menu, and can be used to build Template:L, and so a unit of fuel is usually considered "a bar". To place bars of fuel in a stockpile, create a Bars/Blocks stockpile, or a Template:L with "coal" (found in the "Bars" sub-category) enabled and permitted.
Fuel: charcoal and coke
The two sub-types of fuel are charcoal and coke, and they are identical for in-game purposes, even if they come from different sources and have different in-game names. Whenever you see "fuel", "refined coal" or "coal" in-game, those refer to either charcoal or coke - they are interchangeable, and either one will serve the same purpose, as fuel for the desired activity. (Template:L is not the same as "coal", and does not refer to fuel, but can be converted into coke at a Template:L.)
Both charcoal and coke come in Template:Ls, and are stockpiled in Bars/Block Template:Ls if the "coal" entry is selected within the "Bars" section. There is currently no way (or need) to distinguish between the two when designating stockpiles.
At the risk of repetition, but to be perfectly clear - despite the different names, there is no distinction between charcoal and coke for any game activities. Both are "refined coal" or "coal", or just "fuel".
Charcoal and coke are, of course, not Template:L building materials.
In-game usage
The different terms are found in different places in the game, but all refer to the same thing, Template:Ls of either coke or charcoal.
"Fuel" is sometimes used informally in the forums and in various wiki articles. Since some understandable confusion can arise over the usage of the various terms "refined coal", "coal fuel", "coal", "charcoal" and "coke" (and also "Template:L", which is not a fuel), the simple umbrella term "fuel" will be used in the explanations in this article.
At a conventional (non-magma) Template:L, if you try to add a smelting task and have no fuel, you will see the message:
- No tasks available
Check for raw material access
and fuel if necessary - (Note that this message will also be seen if there is no Template:L to your workshop or needed materials, including fuel.)
You will not be allowed to add any tasks to any conventional smelter until that workshop has access to at least one unit of either charcoal or coke. (However, if you have just one bar of un-used fuel, you can queue up as many jobs as you want - see next...)
If you have queued up multiple tasks and then run out of fuel, you will get an Template:L similar to:
"Urist McFuelUser cancels job: needs refined coal."
Note that a forge or glass furnace will let you add tasks if you have no fuel, and only once a dwarf arrives and finds they cannot complete that task will you get the announcement to that effect. You will get one announcement for each un-fueled task that is unable to be completed. Jobs are canceled when there is no fuel.
When you get either of these messages, you need more fuel - either charcoal or coke will serve equally well.
Coal is the generic term used in the Template:L menu. It refers to a Template:L of either charcoal or coke.
The two sub-types of fuel
There are 2 sub-types of conventional fuel - Template:L and Template:L. Charcoal and coke are identical in use - a single unit of either one powers one activity at a conventional smelter, forge, kiln or glass furnace, or can serve as the ingredient to make Template:L or Template:L. They are completely interchangeable, the only difference is their source.
Template:L does not burn hot enough to fuel these activities or facilities, and (in Dwarf Fortress) you cannot burn raw Template:L or Template:L (although they are flammable).
Charcoal, from wood
Charcoal is created at a Template:L using one Template:L log by a Template:L with the Template:L Template:L enabled. Template:L in the Template:L Template:L are not required but reduce the time required for this activity.
- Required Building - Template:L
- Required Labor enabled - Template:L
- Required Material - Template:L
Coke, from bituminous coal or lignite
Coke is a type of refined coal, and is identical to charcoal for all game purposes. It is created at a Template:L using one unit of fuel by a Template:L with the Template:L labor enabled. Template:L in the Template:L skill are not required but reduce the time required for this activity.
Coke can be created from Template:L, producing 3 coke (net gain of 2 fuel), or Template:L, producing 2 coke (net gain of 1 fuel). Magma smelters do not require conventional fuel for this process, and so the net yield for each is effectively +1 greater.
- Required Building - Template:L or Template:L
- Required Labor enabled - Template:L
- Required Material - Template:L or Template:L
- - plus one unit of fuel per unit smelted, if at a conventional smelter
Bituminous coal Template:Ls and lignite blocks (sometimes offered by Template:Ls) can neither be used as fuel nor converted into fuel or back into stones in any way. They can only be used for standard block purposes -- though they are of course not Template:L!
Because you need fuel in order to refine fuel, you will probably need to create at least one unit of charcoal at a Wood Burner first.
Magma facilities
Magma replaces conventional fuel for Template:Ls, Template:Ls, Template:Ls and Template:Ls. No fuel is needed, nor can it be used, for activities at these facilities. Note that you will still need charcoal or coke for smelting bars of Template:L and Template:L. (And see next section.)
Pig iron and steel production
Note that when Template:L Template:L or Template:L at any location, one unit of either charcoal or coke is required in the reaction (presumably as carbon). Again, there is no distinction - both charcoal and coke serve equally well in the production of Template:Ls of either. An additional unit of fuel is needed to power the furnace at conventional (non-magma) smelters.
