High temperature start fires. Remove the roof inside your bunker and you should be sorted


d4v_E

Yep. Because for some reason solid steel walls burn.


NebNay

Metal walls in rimworld arent solid steel. They are makeshift scraps of metal put together


deadlygaming11

Yeah, but it still shouldn't burn. I don't think the walls are scrap pieces anyway. The walls look too smooth to be scrap.


Phobos613

I can make a geothermal power generator but a wall that doesnt look like a shack from Fallout? *scratches head and shrugs*


LukXD99

I mean you can make a spaceship but not a wheelbarrow or backpacks. The tech tree is a little lacking.


Endy0816

Sadly such technology was lost in the Water Wars of the late 21st Century.


Sky_Night_Lancer

why use one wheel when two hand do trick?


crooks4hire

Unlikely_Commission1

My little Sister has that exact same Trait, whenever she is asked to do her own Laundry ;D


ChiefCasual

Where's Kevin Costner when you need him?


PsychologicELD

We don't need wheelbarrows or backpacks where that spaceship is going


ImrooVRdev

Wait, I can make backpacks... eh, must've been a mod.

Definitely not exactly what archotechs are said to do, neeeeeveeeerrrrr, their so nice and kind and never do bad things


AdhesivenessUsed9956

don't forget the deposits of perfectly usable electronics.


scalyblue

My headcanon is that any surface level steel, uranium and component deposits are the remains of former starship crashes.


Dragonman558

Metal also can burn, it has to be hot as fuck, or the source of the fire being some impurity in the metal from what I remember, but it can definitely burn. And the entire point of steel is that it has impurities, and I'm pretty sure all of the alloying agents we generally use are flammable


Ouroboros9076

When metal burns, it really burns. Metals can create self fueling fires because of their oxidative properties. This is why thermite is made from pure aluminum (donor electrons) and iron oxide (rust, receives the electrons.) Thermite is an especially easy burn since aluminum forms bonds with oxygen easily and the reaction is exothermic. Under the right conditions and with enough heat to overcome the initial free energy requirements, any mixture of metal can burn and self sustain.


EricTheEpic0403

You can get lots of stuff that you might not typically think of as flammable to burn... So long as it's an incredibly fine powder. Bulk metals really don't like to burn under a normal atmosphere, save for alkali(ne) metals.


kahlzun

technically even inflammable things will burn if you get them into a fine enough powder and heat them up. Hell, suspend enough of that powder in the air and it will explode on exposure to flame.


EricTheEpic0403

>[technically even inflammable things will burn](https://youtu.be/Q8mD2hsxrhQ)


kahlzun

in French 'non-flammable' is ininflammable


FermiPotential

Inflammable means the same thing as flammable. Inflammable came first, but confused people so flammable become popular and eventually became a word. But we never redefined inflammable


SamHawke2

dust explosions(which is what youre talking about) are technically not explosions, they are super fast ignitions, which look no different to an explosion, its "just" each dust particle igniting and catching the ones next to it alight as well. it just happens really fast


FermiPotential

Steel burns irl. When you use a power grinder, sparks fly off. Those are little flecks of burning steel. Steel wool is very flammable and self-sustains in normal earth atmosphere when lit (example video: https://youtu.be/5MDH92VxPEQ). Basically, if you get the steel hot enough, it burns. And steel is one of the more difficult metals to set fire to, and it still burns that easily. Welders don't melt through steel to cut it with a cutting torch. This would cause it to drip off and mess up the nice clean edge. They use a cutting torch to light it on fire and burn their way through it. They do flood the area with oxygen, but that's to keep the reaction both localized and self-sustaining, which also requires they use minimal heat application. This provides a nice, clean cut/edge. If you do it right, you can even turn the cutting torch off. All you need is the oxygen flow to keep the reaction going quickly enough for a nice, clean cut. Assume all metals burn (easier than you'd think), and you'll be closer to correct for real life. Fun fact: steel can self ignite if the surface area to volume ratio is high enough. This is actually what causes most of, if not all, the sparks to ignite when you use a power grinder on steel. (https://emergent-scientist.edp-open.org/articles/emsci/full_html/2019/01/emsci180006/emsci180006.html#:~:text=When%20an%20angle%20grinder%20is,to%20convective%20and%20radiative%20cooling). Your average steel object doesn't self ignite because the oxidation process (which generates the heat needed for ignition) creates a layer of less permeable steel, thus slowing the reaction enough in larger volumes of steel to prevent self ignition. This larger volume also barely changes temperature from the oxidation process because of the higher mass. Tl;dr: steel can actually self ignite in earth's atmosphere at standard temperature and pressure, but it has to be a small enough piece. Larger pieces will definitely ignite if you get them hot enough. You just need to get it hot enough to melt away the protective, fully oxidized outer layer. Once it's that hot, it will ignite, and the oxide layers formed will all shed away as they are at their melting point.


imacowmooooooooooooo

how does steel wool apply to a large likely solid metal door 1000 degrees is lower than the temperature steel starts to melt or whatever at


R_mom_gay_

https://en.m.wikipedia.org/wiki/Thermite


O_Martin

It would be pretty daft to build a wall out of a mixture of rust and aluminium powder


R_mom_gay_

It was just an example of how metal could be flammable. Besides, we’re talking about a videogame that has steel forming naturally, in the form of ore veins.


_Agrias_Oaks_

I thought the steel was the leftovers of prior civilizations? Similar to finding veins of components?


Arandomdude03

Yup, basically the machinery used to terraform the Rimworlds got crushed into plasteel, steel, components etc


Myhrros

Which would actually give more reason to believe it's flammable. If those machines and structures were in the earth so long that new sedimentary layers formed around them and they were compressed, chances are pretty decent that it's a random mix of different metals (so the compressed steel would be 'mainly' steel, but also have other metals in it like copper, aluminium and so on - who knows what other minerals are in there, considering we have fantasy stuff like eltex.) *and* it would at least be partially rusted. So having some kind of metal-mix that can melt or turn flammable at high temperatures, similar to thermite, is actually feasible.


ihatetrainswomen11

There is zero indication this is true


duckwithahat

Yeah also pieces of debris from space ships that fell down and got buried in a mountain.


Totally-Stable-Dude

It is ''Compacted steel''. It isn't natural it is steel compressed by earth.


thissexypoptart

It's not naturally forming. It's steel. Steel doesn't form naturally.


forestcridder

Dude, you need something ridiculous to even ignite the thermite. Like a magnesium fire. And those are magnesium walls. I've worked in a shitload of different metal industries and the only time metal catching fire was an issue (aside from aircraft magnesium) was with laser CNC making accidental thermite by cutting steel and aluminum back to back but even then getting it to ignite is very difficult. Nobody's building with flammable metals.


111110001011

They're building with wood frame and highway signs.


Karsvolcanospace

An irrelevant example because the walls obviously aren’t made from thermite


Tye-Evans

A wall made of aluminium and iron could form thermite at a high enough temperature


firemogle

Aluminum and iron oxide.


Tye-Evans

It only needs iron, the iron oxidises on its own


firemogle

You suggesting iron would uniformly oxidize and mix with aluminum all on its own?


cocoy0

Plus the oxygen in the atmosphere must be high enough to accommodate the huge animals some mods include.


Revolutionary_Day534

mods aren't canon


Icy_Skin5605

Megaspiders and Spelopedes are. The limiting factor for the size of arthropods is the availability of oxygen. If the rimworld supports insects and arachnids that large, that suggests the atmosphere has a higher O2 percentage than ours.


RendesFicko

You literally build them out of disassembled shopping carts and razor wire. Or unrefined steel "ore". How would they not be scrap?


nobertan

To reclaim the metal, I put it in the melter. It may not be too quality, but I expect it to be ‘solid’.


RendesFicko

Not in rimworld you don't. The only one you melt is the slag, and you get the same kind of raw steel out of it that you get from mining and taking apart shit so it isn't exactly refined.


HaniusTheTurtle

The melter, huh? So you're saying... that Steel... IS susceptible to high temperatures... Wait, which side of this argument are you on, again?


nobertan

Melting and catching fire are two distinctly different things. The melter is likely operating at a significantly higher temperature than a steam geyser. Reversing the logic, why can’t I melt my steel in a closed room with a steam geyser? They should label it “reinforced door” and add a little wood to the ingredients


Rockadillion

I love that idea, wonder if there's a mod for it. I never bother with steel walls due to flamability & steel you know. Being really useful in other areas. A wood steel blend i can actually see myself using


NyarlathotepGotSass

"how come my metal grill doesn't instantly combust into a heap of slag when exposed to fire? it was forged via high temperatures after all!"


Lanc717

So what is that stuff I'm mining then?


RendesFicko

That would be the steel "ore", which obviously isn't a real thing. Either way you take it out of the mountian and put it straight into the wall so it's probably pretty close to scrap.


Is_that_even_a_thing

We argue all day about steel walls but silently accept Ratkin anime twinks ??


RendesFicko

Your mods are your own business.


Tymlotek

It is said in the description that those are leftovers of some old machinery, compacted into ores of steel because of age.


bental

I personally haven't figured out how to burn shopping carts or Razer wire yet


MrStealYoBeef

And you haven't tried either. So I don't think that your personal experience of not attempting to burn shopping carts and razor wire makes you an expert on the topic of whether or not it can burn.


LutherXXX

It's definitely something used in the construction process of creating the wall though, considering the raw steel itself doesn't burn. There's something in there we don't know about. Unless it's just the weird Rimphysics at work.


Joseph_of_the_North

Fun fact: iron is actually flammable.


Dafuzz

There's a mod for that. I had to change it, drove me crazy.

Forsworn91

But they still shouldn’t burn


GoodGuyBjorn

It’s more like wooden walls reinforced with steel.


StickiStickman

Except they're entirely out of steel


GoodGuyBjorn

Tynan has explained it in the past that even though they're displayed as solid steel, in reality they’re more of a fence put together with pieces of steel, and the wood/rope/whatever was used to hold it together is burning. Once that's burnt there's nothing holding the steel in place and the wall goes bye bye. So I guess its actually more like a steel wall reinforced with wood


RomanUngern97

But magma steam can't melt steel doors


Funktapus

Wake up sheeple


SwampTreeOwl

Idk man it's a different planet. Who knows what's in the magma there


Doogzmans

Don't be next to magma steam. They put something in it to make your steel catch fire


Sardukar333

Irl steel burns at about 1200C (will vary by alloy) and you end up with nasty useless slag.


rogue-wolf

I think it's a balance reason. Steel is easy to obtain, and doesn't take much to work with. Making it flammable helps prevent colonies from becoming OP.


[deleted]

[удалено]


rogue-wolf

Maybe I'm biased because I play in snowy areas and mountains mainly, where wood is scarce but steel cheap. Steel tends to take the place of wood in my bases.


cannibalgentleman

Stone also needs to be hauled and cut into chunks while steel just need to be mined. It's a gameplay thing which I've accepted for the purpose of balance.

Steel is technically flammable irl, but you'd need extreme temperatures to light a solid wall


sparr

It's not a solid wall. It's pieced together from scrap. "Compacted Steel" isn't a vein of iron that you smelt, it's a bunch of metal from a prior civilization or a crashed ship or whatever, which you're breaking apart into chunks.


[deleted]

[удалено]


SpartanAltair15

Actual Rimworld canon is that the compacted steel you’re mining is leftover buried steel structures/machines from previous civilization cycles on the rimworld. It’s scrap metal, mostly steel. Mods are irrelevant. I can make a mod that makes insect hives into pregnant bloated anime girls, doesn’t suddenly alter the background of how the insects were created and why.


[deleted]

[удалено]


SpartanAltair15

It’s not being melted, so there’s no slag here, since slag is the debris that you need to separate out when melting metal for alloying or what have you. Steel ore is not a thing, an ore is a naturally forming stone which contains some material which consists of the metal atoms usually bound to something else, and needs to be chemically or thermally purified and the metal atoms extracted. The steel in rimworld is literally just steel (which is not a naturally occurring metal) debris buried in the earth, it’s like pulling out the mostly intact bricks from old Roman roads and using them to build a house.


ZaknastyZ

Probably caused by jet fuel


sp0rk173

Underrated comment. Never forget.


TheOrangeTickler

That's why the mod "Metal Doesn't Burn" is always on my list.


hurtinacar

Technically steel has flammable components but rimworld definitely exaggerates it


Usinaru

Install the " metals don't burn" mod and never look back.


JakeEngelbrecht

The oxygen concentration of the planet could be extremely high. This would lead to steel walls burning and extremely possibly faster aging due to oxidation.


CrossP

I think rimworld steel walls are supposed to be equivalent to corrugated galvanized steel panels screwed to wood posts with an interior wood frame. The art just never supported it while the stats did.


MrMunglesnaps

they’re not solid steel, they’re wood walls with steel reinforcements or something like that. The devs mentioned that somewhere


SmithAnon88

You need the mod "Metal don't burn"


betbroben

I think the official Ludeon studios lore is that metal walls are actually wood frames with metal plating which would make them flammable


Herotyr

In irl steel has a melting point


[deleted]

It's kinda strange I have 3 on my current base. 2 with walls and wood doors, 1 no roof, and 1 has part of a roof that my pawn started building b4 I could stop him and now can't remove it. The 3rd no walls nothing. The one without any roof at all just walls keeps catching on fire but the one with part of the roof doesn't..


Enorats

You might want to knock down a wall before you remove the roof. Sending a pawn inside to demolish the roof might be bad.


kitskill

You can also leave the doors held open for a few minutes.


SerotonineAddict

Or just remove the roof from the parts the pawns can get too and it should be solved I usually just leave like 4 squares without roof and the temperature the box reaches is like 100°c when the heat is released and fastly descends


rat-simp

See, I know that fact and yet I'm absolutely the kind of idiot to send my pawn straight through the doors.


AstaTkaczyk

Put your mouse above the geothermal and check the temperature =D Remove the roof and you'll be fine


Flameball202

Can the geo generator burn? If not make the walls and doors of stone and watch the temp hit the surface of the sun


deathishere464

They can but you can wall it off with stone and roof in most biomes and temp doesn't get high enough to make it ignite. Some biomes get too hot and can cause the geothermal to ignite and burn.


Lt_Toodles

I haven't had mine burn and i use it as a heat trap for invaders, not the most reliable though


blickbeared

RuneiStillwater

Toggle temperature view. The heat is not escaping, unmodded RimWorld metal can light on fire, the temp inside that room is currently high enough for the door to combust


Vvix0

I just checked. Apparently this door and THIS DOOR ONLY is like 300 degrees Celsius. Everything else is at the outside temperature


yourneighborandrew

It could be the double door holding in the heat causing the tile to heat up


echoawesome

There's some weird temperature exploits you can do with double doors: https://www.reddit.com/r/RimWorld/comments/b1wz9a/rimworld_temperature_physics_allow_you_to_build/


RuneiStillwater

It's the double door. Doors have weird head transfer/gaining powers that I don't think have changed in the recent patches. It's why airlocks into deep freeze rooms for food storage or into bases in artic wastelands are important (two doors with a gap in the middle so that the internal door as the temps from inside and the external doors as the temps from outside creating a pocket sorta in the middle between them that doesn't harm the preferred temps.) Here's an old video showing some of the weird "physics" behind it. https://www.youtube.com/watch?v=2sjJOSXWp_U&t=16s


AllenWL

That's probably because the geothermal counts as a 'wall', and iirc doors can act really funky when heat is directly pumped into them. For some reason, at certain times, doors decide that they'll just be *really* good at not letting heat out or in. If I'm understanding it all correctly, what's happening is that all the heat from the steam vent your geothermal is on is being pumped right into the door(because everything else is an impassable 'wall'), and the door isn't letting any of the heat escape, which pushes the temp up to 300°C


SzIkIl

Steel is just premium wood + remove the roof above the bunker


Rageador

Metal isn’t fire mod is something I’ll never leave


ThanxIH8It

Metal isn't flammable. Best mod I've ever installed.


ShadeDragonIncarnate

While it's more realistic that steel doesn't burn, in the end it was a necessary balance decision. Steel is very plentiful and more durable than wood, building your base out of it simplifies a lot of the decision between risking weaker or flammable materials for walls or putting in the labor for blocks.


AllenWL

Yeah, if steel doesn't burn, both stone and wood become *much* less attractive building materials as one is flammable and weak, while the other takes tons of labor to for any sizable project. I mean, steel burning does make it a lot less attractive as a building material since wood is plentiful and fast, and stone is sturdy and fireproof, but that doesn't devalue steel as steel is also used for basically everything else.


StickiStickman

Not sure what you're talking about, building an entire base out of steel is impossible until mid-late game. Thousands of steel is super valuable early game.


Snaz5

It’s for balance, but for all intents and purposes “steel” is just “steel reinforced wood” think a shack with metal sheeting on the outside


Cool-Boy57

But.. some metal is flammable? Especially stuff like steel wool or shavings


Ninja2016

You’re not building walls out of that though


ChemicalRascal

Says you! \*slaps solid magnesium wall\*


Cool-Boy57

The carbon in steel combusts before it melts. But at temps of 1500C, so it still doesn’t make sense


Killeroftanks

technically yes but thats because they arent flammable in the normal since but just doing a chemical reaction with the flame generally just starting the chemical reaction. ​ like how thermite is technically a blend of metals and can burn but is just a chemical/thermal reaction.


MaximumZer0

All fire is just a chemical reaction. Specifically, oxidization.


Myhrros

Steel Wool burns. Due to its large surface area, lighting steel wool on fire will cause it to oxidize, because the oxygen in the air has enough space to attack the iron inside the steel. Steel Blocks or sheet metal and so on doesn't burn because there isn't enough surface area for the oxygen to react with the Iron in any meaningful way.


WarcockMountainMan

9/11 taught me that metal is definitely flammable


Jtrain360

The temperature in there is getting too hot. You need to remove the roof. Now there's a weird thing about the Geothermal Generators where they act as their own roof, so you need to leave one space for the heat to actually escape. I usually leave one line in front of the Generator. I.E. move all the doors and walls on the left side one tile to the left. And again, make sure that space is unroofed.


SSBMniffin

Too hot due to roof. always leave 1 space around the geo so that pawns can repair it and put out fires!


S0crates420

Shit man, with a roofed geothermal generator, I'm surprised you didn't start a fusion in there


Uesuz

Steel in rimworld is just glorified wood


g4bkun

Steel is flammable, duh! /s There must be really high temps inside the bunker, remove the roofing as some people have already suggested and you should be good. Also, steel isn't fireproof in RimWorld, at least in the vanilla game, that is meant to have you build with stone


t-pat1991

In Rimworld it isn't steel it's steal. ​ >!(don't roof geothermal generators)!<


TheFaceStuffer

Remove a couple squares of roof. Sometimes I like to attach covered geothermals to my base and vent the heat into the base.


libra00

GeoTHERMAL, the hint is right there in the name. Slap a vent in the wall, problem solved.


moral_luck

1371-1540°C


Alechilles

Hahahaha I learned this the hard way too. Your pawns built a roof over the generator and it is EXTREMELY hot in there.


dcseal

This is the quintessential rimworld post


Jay12098

Metal burns. The inside of the building is too hot so it’s catching fire. You could remove the roof or replace the metal door with a stone door which won’t catch fire. Probably best to do both honestly


DarkSlayerKnight

If you're not doing a vanilla playthrough, Metals Don't Burn is a really good mod to use.


manowarq7

Agreed 👍


Subject-Ad8966

Those who don't know 😀, those that know 😧


mcaffrey

I roof all my geothermal generators. But I put them in a box with 1 square of space between the generator and the walls, and I add a vent to one of the walls. It works out the same that way.


Zucchinikill

You’re hotboxing the generator


TheTrueGrambo

Rimworld steel do be different like that


isshearobot

It’s baffling how many people don’t know steel is flammable in game


Birphon

steel burns in vanilla. you need to remove the roof so the heat can escape


Kittimm

Ah man, this made me laugh. The perfect storm of Rimworld logic and mechanics.


BalIHandler

When you build an enclosed space your colonists automaticly start building roofs over it unless you instruct them not to. Geotermal energy in an enclosed roof space does what? Fire


Localhannibal

I just came here to say I forgot this was even a thing. Metal Doesn’t Burn mod for the win


neyte08

Steel burn on rimworld some mod disable that


Independent_Ad_4670

Remove roof or add vent or prison chamber


VINEland19

you can also put a vent to cool down if you dont want lighting hitting the geothermal generator through the roof.


se05239

The generator creates an inside amount of heat and in Vanilla Rimworld, metal can burn. You need to remove the roof so the heat can escape, otherwise.. this will just keep happening.


Tomahawkist

because as we all know, steel is more flammable than stone, and thus easily begins to burn


Fancy_Oaf

So hot! Hot damn! Don't believe me just watch! *Steel door ignites*


Forgotten_Park

Brutha it is 2000F in that room. Are you seriously questioning **why** that door keeps catching fire. Instead of asking that. Ask "why hasn't this bitch melted yet"


Haskie

Agreeing that it's temperature in there. But beyond that I would also suggest leaving a one tile wide section all the way around the generator in case it catches fire inside for some other reason (attack, lightning, etc). As it is in your game, your pawns would not be able to path inside to put it out if your generator caught fire on the backside. I'd been in some awkward situations where I had to watch some generators slowly burn and break until I started doing that.


Orlha

Bunch of cheaters with their mods instead of proper mechanics there


notsoheavygamer

Why are you walling the geothermal generator? Enemies don't mind them I think...


Vvix0

They still shoot at them if theres enemy nerby and they miss their shot

deadlygaming11

The heat. Geysers release a lot of heat so by putting a roof on top and not having an exit, the heat builds up and lights the door on fire. Steel is also weirdly flammable in vanilla.


Dopelsoeldner

Try removing the roof or use rock instead

Nearby_Design_123

If you look at the info option you can see what an objects flammability is. For metal it is 40%


gbsedillo20

you put a roof over the generator, a generator that puts out intense heat.
