Volcano Cooling Problems!

[Gonhog]

As anyone who plays ONI knows, the game is about finding problems and solving them. 

On my world, I lucked out on the geyser side, having a Chlorine Geyser (Still kind of useless),  a steam Geyser, a natural gas geyser, and the iron volcano above. Seed is 166847942 if you guys want to check it out or experiment with it.

As you can see in my screenshot, the volcano produces 28.5 Kg of iron at 4580 degrees. That's a lot of iron at a very high heat.

The problem: I have power (Thanks to those natural gas geysers), and after watching Brothgar's video on Volcano power (The only video I can find on this subject) I have seen that it's a project to use the power from a volcano. I don't even want the power! I just want the iron so I can bypass the iron refining process and get lots of refined metal to rewire by base with conductive wire.

I have experimented in debug mode on a copy of the world with some steam power, and didn't get it to work. On my original world, I tried with wheezwort cooling (screenshot), but the wheezwort would overheat and the dormancy cycle of the volcano was too short for it to be a steady decline in heat. 

So I come to you, oh people of ONI, to see if together we can overcome this challenge and come up with new ways to solve it! I'm just asking for help from people smarter than me. Thank you!

There is no way to cool down the Geysers that I have found. I tried to do it for Steam Geysers with Weezworts and Hydrogen and the Geyser itself stays at a set temperature even when dormant. Klei must have seen my pics of cooling down a Geyser with stored Ice and Snow where over time the area naturally cooled everything in the area and it being adjacent to an Ice Biome.

Try slowly putting molten iron into coolant, then transport it somewhere else quickly.

Why didn't The Steam engine work? Looking massive, but IT has The right Componenta - doorpump, metal tile / door temp control and Steam and heat source?

If you're talking about the actual Geyser object itself, there's no way to cool it (at least, not for a few thousand cycles) because it's Primary Element is Abyssalite, which means it uses the traits of Abyssalite (aka negligable thermal interaction).  But that doesn't have anything to do with what OP is referring to, which is cooling the products of the Geyser/Volcano to a usable temperature.

@Gonhog There is an older thread from another user, @Kasuha, who demonstrated a design for a fully "tamed" Gold Volcano with automated collection and cooling of the Gold produced.  Have a gander.

I would like to note that the build referred to #1 is done before they fixed the cooling and #2 it is using a gold volcano, which is the volcano with the lowest amount of thermal energy of all the volcanos.

 

I honestly don't think this build works anymore, just because of the changes in cooling. - I might be wrong.

If your trying to get the metal, Currently I have a gold volcano which i decided to crack open really early on roguhly cycle 40ish. 

I just pumped in enough polluted water from the surrounding slime biome to cover the first tile of the volcano, and ever since it has been cooling the metal and boiling some water. It is getting the metal to about 70 degrees without any help, and once the volcano goes inactive I expect this to drop further as the polluted water has not hit 30 degrees yet.

Its kind of a temporary solution, but heck its been working for me so far and the volcano will go dormant soon enough. I will either use a pump and aquatuner to cool the polluted water and put it back in during that time or I will make a new design. Your volcano does put out more metal than mine though so if you do dump water there I expect you will probably end up heating the water up quicker.

Check out the actual output

https://onical.ga/

Here you can calculate the actual average output of your volcano. Then it is simply:

iron heat capacity * volcano average mass output * (output temperature - wanted temperature) = kilowatts of cooling you need.

Choose a production

When you have that down you can look at what you want to produce and what you have at your disposal to use the heat from the volcano. There are several mechanics that are very profitable:

Heat capacity decrease through material conversion means you are destroying some of the heat:

polluted water => steam => steam turbine / food and toilets after massive cooling

(fertilizer) => dirt => sand => water sieve / deodorizer

Heat capacity increase plus generating massive amounts of power, CO2 and polluted water:

crude oil => petroleum => natural gas => natural gas generator

You most likely want some combination of those things.

Choose a rest cooling method

Whatever you are trying to produce you most likely need to cool that down further. Wheezeworts only cool for 12kW and AETNs for 80kW. The most powerful cooling method right now is to heat up polluted water and then running it through a sieve. If done "perfectly", right below the boiling temperature you are cooling for about 2100kW. In this case you want to heat up a polluted water reservoir indirectly for example by putting an aquatuner inside it, and then using that aquatuner to cool down the rest of your products.

Create a Vacuum around the volcano and make it accessible

In any case you need to be able to dig up and transport that iron away with exosuit duplicants. So you want the area to be accessible which means you need a vacuum around the volcano.

How to tame a volcano: build a place for steam turbine with smal cooling on top, add some hydrogen to create pressure gradient, build steam turbine, drip water untill it works and drip more if steam gets deleted.

The kasuha cooler works perfectly well for ALL types of output.  Even large magma if you have a large enough cooling buffer as to not boil it out.

I use that build in my current base for 2 iron volcanoes, with some small alterations for automation. It still works great.

I guess i stand corrected then

The steam Engine didn't work because the steam pressure was not enough and I couldn't figure out how to transfer high amounts of cool steam from top to bottom without door system (which deletes and lets a ton of steam through when being loaded off screen, its a bug). If you want to try a better setup that deletes most of the heat, go ahead, but I'm too stupid to make it work.

Ya, I tried pumping some water in there and it turned it all to steam instantly, increasing the heat transfer between the iron and the radiant ventilation pipes, melting them. I cracked it open and released the steam, which was the reason for the wheezworts on the side. Iron volcano's make tons of heat!
