Hello,

For start: Me speak English well, is it K ? ;P

And to the point:  I love to embark at ocean sites, especially river deltas.
Most of that maps are covered by driftwood, totally useless, what makes my eyes hurt ( we do not like when potential resource go for waste, right?)

I am lazy person, I would love to see driftwood as pick-able resource ready to be moved to stockpile, but i have to agree with most of players that, as in real life, its way too low quality to make something out of it. 
I menaged to read across some topics and i found it as best, simple and new solution to put all that driftwood into wood furnace !
We will get: reason for driftwood to exists, free ash, happy players, tons of (burning) fun !

(exits room mumbling about flames...)

That's actually a pretty good idea.

[Robosaur]

You could probably make a shitty shack out of driftwood

[GreatWyrmGold]

Or crafts. Driftwood is naturally smooth; I bet a skilled woodcrafter could make a pretty good figuring out of driftwood.

I don't like the idea of driftwood being used to make charcoal. I am not very knowledgeful on the issue but I suspect it would be far too much impurities in seawater-soaked wood to produce industrially acceptable coal.
As a mere source of heat of light, I definitely agree it should be in, bu first we have to really have need in heat and light. Crafting driftwood I think is okay too, but not worth introducing per se.

Dunno if it would make good coal or not... but driftwood burns insanely well as is.  Don't see why you couldn't make coal with it.

Wikipedia says its smoke is carcinogenic. Not that the dwarves would mind while drinking in their pitchblende or lead mugs...

[TheMaciej]

All smoke is carcinogenic more or less as long as it comes from natural coal burning, more pure coal = less toxic smoke.

Salt in coal do not make any difference since it will stay in ashes after burning (reduce calories / dry mass slightly due to addition of non-burning  inert)

We could even say that dry driftwood will make charcoal faster than fresh wood since it is eroded by water and, after drying, will make material with higher porosity = fire will get it faster.

Its an old technology to burn driftwood in charcoal pits, iv seen it myself at Baltic sea coasts.

[kilakan]

Um.... isn't all smoke carcinogenic?

[thvaz]

From wikipedia:

Spoiler (click to show/hide)

Burning driftwood can produce polychlorinated dibenzodioxins (PCDDs), also known as the misnomer "dioxins", which are carcinogenic. For this reason burning driftwood is not recommended.[1] The formation of PCDDs is well documented when organic compounds are combusted in the presence of chlorine, which is present in driftwood as a result of soaking in seawater.

[kilakan]

Ah well then... I guess I better stop having bonfires on the beach's.

Actually I think dwarves wouldn't mind carcinogenic smoke, they don't know a shit about cancer and stuff. I was more afraid of seawater-induced impurities rebinding the metal ions in smelted ores rather then CO reducing them to metallic state as with normal coal. I might be completely wrong here though, it's just a suspicion.

Melting pots (at last modern gas heated, electrical heaters excluded from topic ) have separated heating devices and pots, so there is no way that fuel, ash nor smoke get into the contact with metal.

Blast furnaces its different thing, they include mixing metal ore and fuel, so you are partially correct BUT
After blast furnaces we receive raw metal, for melting we need refined metal, and it includes removing any leftovers from fuel.

Standard way is: blast furnace -> rafination -> addition of alloys -> bar casting

Im working in lead melting factory so i have first-hand information

[nanomage]

Very interesting! What would you say about dwarves' assumed 1400 level of technology? How would they refine the smelted metal after they cast it from a huge pile of ore and coal? Or would that little amount of impurities have no measurable impact for their purposes?

[TheMaciej]

I think they rafine them to some point, its required for any form of casting (or hammering, im not sure if raw metal is hammerable, lead is for sure not, cracks if hitten)
