Arc Furnace not Offgasing?

[Grimm Spector]

I have an arc furnace in what appears to be a sealed room, but when processing things it doesn't seem to be offgasing at all...any clue why?

[Bunyan]

What gas were you trying to smelt? Some give off more than others, and copper does not give any off at all.

Or, did you mean the furnace and not the arc furnace? (these are often confused)
If you meant the furnace: Is it hooked up to a vent of some kind? Pipes that are left open-ended are actually still sealed/closed. That includes the arc furnace...it needs a vent to let off the gas

I've tried copper, lead, iron, and gold.

I meant the arc furnace, in my first playthrough I poisoned my base air supply having my arc furnace inside, pollutants and CO2 gasing during smelting, which makes sense since that's what happens when you melt rock.

Arc furnace has no place to attach pipes, it's just in an empty sealed room. That room has an active vent to pull gas into my filtering system, but it is currently off, and bugged (thinks it has no pipe attached but). Wondering if the vent is the culprit. May try redoing the pipe system as a whole, or at least breaking the vent and testing it.

was this ever solved? I have the same issue

Are you using ores from deep miners?, they don't degass

[dupa]

Ores can be "fresh" or degassed. If you process a stack of ore in a furnace, but the temperature or pressure are out of range, the ore will drop out of furnace, but the gases will be extracted. This stack of ore will no longer produce any gas. Before we had this feature, you could just loop the furnace output to the input and get infinite gas. And as LoboFH just said, deep miner ores are degassed to begin with.

I wrote a suggestion a while ago to make a clear distinction between degassed and non degassed ores. Let's hope the devs implement it.

[KingdomDestined]

yeah deep miner ores were the issue... do rocket ores have that issue?

Question, so when you mine by "hand" with the drill you still get the gases but when you use the Auto miners/Deep miners you don't get the gases anymore??

Hand drills and auto-miners produce ores with gas afaik. Only Deep Miners produce ore without since those comes out of a centrifuge.

Originally centrifuges were able to produce ores with gases, but then people started building loops with Furnaces and Centrifuges which could spawn infinate amounts of gas. The Devs decided they didn't like that, so now ores from centrifuges have no gas in them.

[MrTenneal]

Wow.. that's crazy, i never thought of using the centrifuges that way..

[Klausberger]

I rebuilt and remade my furnace like 20 times, as I never noticed the "degassing" hint of the Centrifuge.

It's immensely unintuitive.

- Ores without gas should be clearly identifiable.
- Centrifuges should emit the gas they remove.
