Sandustry Steam Turbine Guide: Energy and Depleted Steam

Understand the machine's job before placing it

The Steam Turbine combines a material route and an electrical route. Steam must reach the machine, and generated Energy must have a connected destination that is not already full. Checking only one side leads to common false diagnoses: visible Steam does not prove the turbine can export power.

Its material output is Depleted Steam rather than ordinary Steam. That distinction preserves the cost of generation. Route the depleted product deliberately instead of returning it to a chamber that expects rain-producing Steam.

Follow the documented input and output rules

The official turbine page states that one Steam pixel produces 10 Energy and one Depleted Steam. It also requires connection through an Energy Connector to a battery with free capacity. A full or disconnected battery stops useful conversion even when the intake looks supplied.

A Condenser turns Depleted Steam into Water. The official page warns that Depleted Steam cannot become rain, so do not copy a normal Steam rain collector for this output. Keep the two gas streams identifiable until they reach their intended destinations.

Build a serviceable layout

Place a visible Steam intake above or beside the documented receiving area, connect the turbine to a dedicated test battery, and give Depleted Steam a clear route to the Condenser. Add Water collection below the condenser with enough space to prevent backup.

Keep an Energy Connector visible and avoid hiding it behind another system during commissioning. Separate the test battery from a large network at first. A small battery makes energy gain easy to observe; once the ratio and flow are confirmed, connect the module to the wider grid.

Measure sustainable throughput

Treat Steam Turbine as one boundary in a longer chain. Start with empty or recorded buffers, count how much Steam and available battery capacity reaches the input during a fixed interval, and compare that with 10 Energy per Steam pixel plus Depleted Steam leaving the output. Record material still inside the chamber. A growing reserve before the machine identifies an intake or processing limit; a growing reserve after it identifies a collection or destination limit.

Do not infer an exact rate from a short animation. Let startup material clear, repeat the interval, and test again after saving and loading. If supply arrives in bursts, record both average flow and the largest burst. Add parallel capacity only after the same boundary limits two clean observations. Otherwise extra machines can hide a routing fault while consuming space, power, heat, cold, or scarce construction resources.

Diagnose the first failed boundary

If Steam is present but energy does not rise, check the connector, battery path, and free capacity before changing the gas route. If energy rises but stops early, compare battery state with Steam inventory. A full battery is an output blockage, not an input shortage.

If Depleted Steam accumulates, inspect the route to the Condenser and the Water destination. If expected rain never appears, confirm that the gas is Depleted Steam; its inability to form rain is documented behavior. Use condensation for recovery.

Apply the v0.5.6 version notes

The official v0.5.6 announcement does not state a turbine ratio change, so the current wiki value of 10 Energy per Steam remains the documented basis. Still label measurements v0.5.6 because power supply from Voltblubs and connected factory demand changed around the same update.

Update #3 boosts general Voltblub output without publishing an exact new rate. When comparing turbine and critter-assisted power, measure both on the same version and observation interval. Do not remove the turbine because a temporary petted-creature boost fills a small battery.

Validate the design in a small test cell

Build one isolated Steam Turbine with a limited input sample, visible output pocket, and a way to stop supply. Label the game version and active mods. Observe the expected transformation, any byproduct, where each pixel settles, and what happens when the destination fills. Then clear the cell and reverse the loading order if two materials share space. A repeatable small test gives a stronger design basis than a screenshot of a large factory.

After the test passes, copy the geometry into production while keeping access to the input, output, and removal controls. Leave enough room to inspect or drain the machine without opening a neighboring line. Recheck the route after patches that mention the machine, its materials, density, heat, fluids, energy, or building events. Keep the prior measurement with its version so a future change is visible instead of becoming an unexplained slowdown.

Use the pre-launch checklist

Before opening full supply, confirm that the input really is Steam and available battery capacity, the planned result is 10 Energy per Steam pixel plus Depleted Steam, every required power or temperature connection is active, and no incompatible material can enter. Verify output clearance, overflow capacity, a shutoff point, and a safe path for the player. Take one recovery save before connecting a rare or destructive input.

During the first long run, compare starting and ending inventory at every boundary. Watch for material trapped inside building cells, a mixed network, a full destination, and a reserve that only delays failure. If the line remains balanced through its normal burst and restart conditions, record the observed rate and promote the module as the factory's current versioned standard.

Field facts

Troubleshooting

• Steam reaches the turbine but Energy stays flat.

  Trace the Energy Connector to a battery and confirm that battery has free capacity.

• Depleted Steam fills the output.

  Clear the Condenser route and Water destination before reopening Steam input.

• Depleted Steam does not make rain.

  That is expected. Send it through a Condenser to recover Water.
