Magma-Fueled temp-controlled Oven (for making Naptha, boiling PH2O etc etc)


Recommended Posts

Made a little video showing a simple little oven I've built. Been thinking of ways to easily make naptha, and with the new metal tiles this seems pretty legit.

Credit to @Neotix for the inspiration

Abyssalite rooms. Upper chamber has access via naptha locks, and filled with 2kg of natural gas (could be any gas depending on your intended use)

Bottom chamber contains Magma within a vacuum - also with naptha locks to enable access to dig out/refuel magma when depleted. Mechanised airlock is set to an open state by default (using NOT gate) and will only toggle shut when the thermo switch above toggles it.

Thermo switch set to active if below 200 degrees, and wired through a NOT gate as mentioned above - open airlocks wont transfer heat, however as soon as it closes it begins to heat up.

Very quickly the room starts to warm

Once the thermo switch toggles, the airlock opens again and stops heating the room.

Looks good! Except, y'know, getting dupes to bottle lava. Won't it solidify before it reaches the pump?

Not at all - they can carry it in bottles no problem - once you set up a vacuum area to your magma it's just a case of running them down there.

This is the little build I threw together for a previous video showing how you can easily build something to contain the heat - throw a pump inside and you're golden :)

So, in a non-debug world, would you have to tunnel into magma inside a vacuum? Because I think that any material gas pump would melt inside a lava chamber.

 

Then again, I might just be missing something.

Make use of the fact you can build and destroy tiles diagonally, and it's incredibly simple to make a small space a vacuum without using a pump, from there you can expand the vacuum externally :)

A small improvement would be to move the thermo-sensor to a hydrogen (or natural gas) filled tile beneath the hot plate so you can have make the active room a vacuum, if needed.

How do you mean sorry, i'm not following? (I've just finished a lengthy stream and am a little fried, so be gentle...)

If you placed it below, you would be measuring temp of the boiling plate, this way you are measuring temp of the boiled contents, important difference when making petrolleum. Also putting hydrogen there would need to be very fine tuned, too little and the hydrogen will not transfer enough heat to the sensor, too much and thermal capacity eats all the heat.
