Hot Steam Vent

The scheme is designed to obtain water and electricity from the hot steam vent. The output: water, with a temperature of about 33ºC, and electricity in the amount of 1350W (at the worst moment, before the eruption) and 3400W (at the best moment, somewhere from the middle of the eruption), minus turbine consumption (1200W, almost constant).

Efficiency of scheme may be slightly increased by putting another turbine, if you get enough active volcano (at the same time water temperature at the output will be slightly lower). Well, as an option, the water can be output without cooling, and cool it with one of these schemes.



Description
Steam erupted by the vent has a temperature much higher than optimal for turbines (200ºC), so 3 of the 5 ports of the turbine are plugged. The exception is the right turbine - it runs from the Aquatuner (and a little bit from the general circuit), it cools it down too.

Water from the turbines goes to the Liquid vent, and if the steam pressure at the Steam vent is lower than 4.6kg - it pours into the chamber, and if higher - it goes into the cooling circuit. If the pipe in the circuit is full, the "extra" water is taken out of the circuit. At the output of the circuit water with a temperature from 0ºС (at those moments when the Steam vent stands, and the water repeatedly passed through the circuit), to 76ºС. On average (if draining it into a pool or liquid reservoir) about 33ºC.

The looping coil is not used for better cooling of the turbines, but to get more water into it.

Sensors



 * Atmosensor (at the Steam Vent) <3500...4600gr. (depending on the activity of your volcano)
 * Atmosensor (at the Aquatuner) <20000gr.
 * Liquid pipe thermo sensor >14ºC.

Materials

 * Insulated tiles (lighter in the screenshot) are ceramic, the rest are mafic rock.
 * Tempshift plate copper (you can gold/aluminum/iron/diamond). If you don't have that much metal, some of the tiles can be left out, but then you have to spill crude oil on the floor. This will reduce the usable volume of the room for steam, which is not a good thing.
 * Aquatuner - steel, automatics/wires - anything.
 * Crude oil under the Aquatuner - 200kg. Water under the turbines is 200kg.
 * Tubes: from the turbines and to the Liquid vent - insulated from igneous rock; in the Aquatuner chamber - ceramic; the coil at the turbines - the upper (looping) part - granite, the lower (in the water) - igneous rock. The coil has 2 Radiant pipe inserts (yellow in the screenshot) of lead (copper, etc.).

Such a different material pipe is used to keep the temperature of the turbines closer to 95ºС (this should be sought in any scheme with forced cooling of the turbines). If the temperature is higher, there will be a risk of overheating the turbines, if lower - Aquatuner will spend a lot of time for meaningless cooling of the turbines. As a result, the water will leave the circuit with a higher temperature than it could have been.

Before starting the circuit, a vacuum must be created inside the Steam vent, in the Aquatuner chamber and between the 3 Heavi-Watt joint plate. In the turbine chamber, oxygen, with normal pressure (1.8kg cell).

Electrical
In the general view, I show the wiring conventionally (as I do in some of my articles), just connecting everything with wiring Conductive wire. There can be many variations of the power system at your base, as well as ways to take the wire out of the circuit. One such is shown in the screenshot to the right.

Questions from readers
Question: why are so many turbine ports plugged and why is the turbine supplied with 350C steam?

Answer: The power generated depends on the inlet temperature (T_steam) and the average mass (M_steam) processed per second. Falling 800gr/sec of steam (400x2 inlets) into the turbine, with a temperature of 355C, the turbine produces 842W, which is the most optimal mode of its operation.

Question: A steam turbine is in fact hard capped at 357°C.

Answer: the steam reaching the turbine has a lower temperature due to the heat capacity of the Tempshift plate (see screenshot on the right).
