Couple of question about playing with fire

[Cipupec2]

I am trying to tame a minor volcano, here is an illustration of what I am going for:

I am expecting the magma to flow unto the metal plate forming igneous rock, which will then be cooled off and then swept away. I will be using:

1. Vacuum room to prevent heat transfer to anything but the cooling plate.
2. Pipes filed with petrolium connected to steamturbine to cool off the metal plate.
3. Cooling mechanism to cool off the sweeper arm
4. The water tank above as emergency shut off in case I **** up or don't need igneous rock anymore.
 
Question:
1. its tricky to put the sweeper in way that it touch the cooling pool and not block its range. The way I did it the liquid tile is only 36.7g worth, will that be enough to cool it of? 
2. Any advice, ideas on how this can fail or improved?

The petroleum in the pipes will evaporate into sour gas, break the pipes and possibly leak out into the vacuum.

... then the water lock breaks and your world is doomed..

[chemie]

...and you need robo miner before sweeper will have anything

What about the 1 question, it's the pivot for my whole design?

I have added a cooling chamber as failsafe, if  heat reach dangerous level the doors will disconnect the chamber until it cools off

Are you sure? that not how it works with gold volcano iirc you need large enough quantity before it forms

Huh?  When you freeze water it makes loose balls of ice, not whole tiles.  Why would magma be different?

[Kabrute]

The quantity converting to a solid above 150kg or so makes whole tiles instead of pickable items

Only if the mass is small.  If you freeze a body of water, you will get ice blocks.

Magma volcanoes produce so much magma that they cool into entire blocks of igneous.

[Cipupec2]

This is what I ended up with

I would not recommend this build, its painful to setup and preforms badly. 

[Neotuck]

use a steam turbine to cool the magma

[Cipupec2]

That what I did. Overall the idea is ok but after few runs I see that pretty much everything needs polishing

[Cipupec2]

Well I had another go at it, addressed some misconceptions I had and streamlined it.  

Still need to decide how to address couple of kinks but overall it does what I want. Though practically I would probably never use something like this, instead I'll just do what everyone else seem to i.e. crawl up into space, tap solar power and spam the turbine/tuner solution.

[Neotuck]

This is my solution to taming a gold volcano, should work on other volcanoes as well

It's cooled by looping the petroleum though an aquatuner off screen, a thermal sensor controls a shutoff valve when the desired temp is reached

It works so well I was able to pipe my liquid glass from my glass forge here as well too be cooled

most gold/glass is near 0C by the time it leaves the conveyor rail 

[Cipupec2]

Yeah the basic aquatuner loop works with wherever you put in the cooling tank. The problem with these builds is that they are very power hungry, obviously late game this the way to go i.e. simple and quick, but the challenge for me was to make the most power efficient build.

To that effect I tried to make a two-stage cooling via steam turbine, first stage is the hot tank cooling to bring the temp to the steam turbine minimum operating temp (either through direct contact or petrol loop) and only then move to the second cold tank which use the aquatuner to shed the rest to comfy  levels.

One of the issues i had is that it even with cooling plates it took a while for the material to exchange temperature. I like your solution to snake the rail through (less costly higher conductivity) metal plates, I think it would go well with clock to disable the sweeper through most of the day thus reducing the chance of hot materials leaving or the need for such a big tail.

I thought so too but if the thermal sensor is set to -40C (any lower and you risk pipes breaking at the aquatuner)

given the large downtime of the volcanoes, this build has plenty of time to reach -40C (Including all the metal tiles underneath)

I have not seen it get above 0C during eruption periods

As for the power requirements it's not that hard, 1200W full time with 1680W during eruptions (3 coal generators can handle that!)

<<---Edit--->>

1200W isn't really full time, at least half way though the volcano downtime you'll reach -40C and everything will go idle till the next eruption period 

[Cipupec2]

That a sound plan. I'd also use polluted water which is cheaper to come by and has higher heat capacity thus cooled more efficiently by the tooner I believe) but wasting power on overcooling doesn't sit well with my goals for that build.

The way I see it the advantage of using a clock is that increase the time the materials spend in the tank, which make the process a little more precise reducing the need to waste energy on over cooling and materials or overbuilding the tail. The disadvantage is that it hit an miss unless you are using a water clock timed to the end of its eruption period (which would be an over kill here)

 

[Neotuck]

Don't use polluted water, or clean water for that matter, you'll risk boiling it into steam and that will break your build real fast

Also the increased thermal capacity doesn't help much, most of the thermal capacity of the build comes from the metal tiles underneath, If you are worried about increasing the thermal capacity just add another layer of metal tiles underneath 

Besides it's the thermal conductivity you want which petroleum has more, allowing it to pull heat away from gold faster than water

clock isn't a bad idea, but it isn't necessary as I said before the gold is VERY cold when it leave the build so leaving it in longer is kinda pointless

[Cipupec2]

In my build it would be a bad idea since I am using high temps and wish to maintain vacuum. But in your build I believe it should work, since the gold volcano produce too little heat to matter for ~10tons of water cooled to ~0c  with tempshift plates to spread the heat.

As for better cooling efficiency, I meant if used in the tuner loop, since it removes 14c from liquid in the pipe its my understanding that the higher the heat capacity the more efficient the process is.

It is actually, however if it makes a difference in the long run is debatable

Your idea should still work though, please post pics when you finish

Here is my version.  Water is maintained at 5C and peaks to around 6.3C during an eruption.  The petroleum is allowed to go to 270C and the steam that cools it was being used to power the first rockets.  The only issue I have had with the build was using an insulated igneous pipe on the aquatuner intake.  During a dormancy period it allowed the polluted water to get hot enough to boil so only use insulated ceramic inside the exposed petroleum area.  Even with a 40+ cycle dormancy the water in the cermaic pipes only went up to around 80C.  Alternatively one could use a constant flow version so the pipes are never idle which would also solve the issue but shutting off the tuner by automation is far easier to build.
