how to reach enough pressure/temp on furnace?

[Rodrigo]

I hooked the furnace to 2 tanks with H2 and O2, did the correct 1:2 ratio with a mix valve, tanks where full and all, i often can make steel, but invar using iron and nickel just become some weird reagent ore...

on the output side of the furnace, place a pipe or two then add the on/off pipe value to cut off the output.. then the temp/pressure will go up.. be sure to add a vent to allow the output to escape when not in use as it will blow up if the pressure gets to high.

i know im doing something wrong but i actually want to increase the pressure and temp for the nickel / iron invar reaction, correct me if im wrong but they need something something to about 18mpa and some other think... like 1.5kpa or something, i dont know how to get this much pressure and temps

[MrTenneal]

use the F1 info for exact temp/pressure as a recent update changed all the pressure / temp for making stuff so the wiki maybe off..


easily for me i use 1 blue oxite and 2 red volatiles to create enough fuel. to start the furance. then i switch to the fuel input to help bring up the temp/pressure..

this is straight from the stationeer wiki "This can be done by separating gases into tanks using atmospheric units and piping individual gases through a mixer and a Pressure Regulator or a Pipe Volume Pump connected to the furnace input. Output should also be extracted and vented/recycled through a backpressure regulator to keep furnace pressure in check. The optimal gas mix that burns completely is 1 part (33.3%) oxygen to 2 parts (66.6%) volatiles, other mixes would also work but leave you with leftover oxygen or volatiles depending on the percentages used. It could also result in lower temperature if that is desired, but you could also use a volume pump with a lower fuel input setting. "


so on that you need to create on the input side a pipe system that will pump "fuel" pressure into it and a back pressure or manual switch to control the pressure on the output..

my setup i do all the above but i use a canister hooked onto a mount to feed it, a distance away from my main stuff.. as i have forget a few times and blown up my base..

but i mean, i used the portable tank, wich holds about... uh... 7.9mpa, (once i went to 11 and it exploded :)

though i kinda need like 20 to make invar

[Teamkiller]

Portable tanks contain not that much amount of gases (those moles - that what matters). You'd better stick to ice-smelting until you can get normal gas piping setup. You will need about 10 oxite, 20 volitiles ice + some water ice or additional oxite (I don't remember how many i put in one by one) to smelt advanced ores.

what i didnt understood yet is how to balance the proper pressure/temp ratio, i can do steel no problem, but invar required something like 1,2K kelvin temp and 18Mpa, i have no idea how to balance those. Firstly i load up the furnace with 750kpa of sorta nicely mixed o2 and h2, when i lit it it blasts the temp and pressure up and just starts decreasing from there... seems like i need a guide on how to set up a proper furnace..

[MrTenneal]

Hope this works....
I CAN NOT take credit for this.. i found it one day and saved it. It gives me an idea on how to construct my own version of a system to smelt.

if someone knows who made it let me know so i can give credit to them..

thanks but that looks a bit too ADV for me yet, i just recently begun, what i have watched before are videos with the exact fuel mixture 66/34 (for some reason my mixer only makes 67/33) cans.

none-the-less, put that fuel into a piping, regulate to 350kpa exactly into the furnace, fire it once and rapidly place the ores, however, in their videos the gauge on the furnace blast off crazily, mine just go a little into the green area, but those videos are from 2018 so i think something changed and this recipe doesnt work anymore? i guess ill just manually place the ice and volatiles, not classy but... i guess thats it.

[gearhed502]

https://youtu.be/kwa4gMtBLDo Try this method. I used it to make all the basic alloys after the latest update. Just be carefull when making fuel, you can overpressure the pipes quickly if you're not paying attention.

[MrTenneal]

well.. time to add to my furnace with this info from that youtube..

[Rodrigo]

That setup works for me to make most of the ingots, except invar, it seems ill be needing something different because it cant seem to ever reach the exact pressure/temp ratio with invar.

That is, when the temp is ideal 1,2kk to 1,5kk the pressure is too low, any clues how to increase the pressure while keeping the temp on that kind of setup? Invar is a tricky one...

[MrTenneal]

yea the pressure is normally a problem for me when doing it.


So I know its not super efficient but what works for me is, I have a couple of small tanks that have been pressured to have 8-9 Mpa in them with a volume pump to a T junction, another volume pump line that has fuel in it and a dump switch to the filtration line to empty the pressure when done.. .

I have two signs on the ground that I label with the range I'm looking for so I don't have to hit F1 to look or look away to a piece of paper.

So I have to manually set the pressure regulator (set to 18MPa) on the input and the back pressure (set to 19.7MPa) on the output

so I give it a fuel shot to start it up.. when I need to boost heat/pressure I give it a quick fuel squirt, and keep doing it till I get near where I want it.. and if the pressure is to low I can pump a little bit of pressure to bring it up. and normally the heat is up a little bit I let it come down.

I'm not good with IC codes, and I spend time tinkering with the logic circuits.


thanks for that video BTW I went back and added the circuit for the auto smelt, which has helped the process..

I connect a tank to the exhaust from the furnace. I have a pump connected to pump hot gasses back into the furnace. Thus increasing the pressure with hot gases.

[JeanDeaux]

Woa, they really changed the Invar setup since last I played. I used to be able to mix 6 volatile with 3 oxite and viola. Looks like the new mix ratio is 9 volatile with 30 oxite. That's a big change.
