Condenser Turbine

The Condenser Turbine is a structure unlocked by the technology Condenser Turbine. It is described as having "75% the efficiency of a steam turbine but 99% of the steam used is returned as water." This means that each turbine requires (60/(1-0.25)) 80 steam per second, while returning 99% back as water, to create 5.82MW of power.

The Condenser Turbine has one fluid connection for input of steam with a temperature of 100 to 999 degrees C and one fluid connection for the output of water--this means that unlike the base Turbine, you cannot connect one Condenser Turbine to another in a chain. When steam is sent to the Condenser Turbine you can click on the structure to see it be transformed into Condensing Steam. The Condensing Steam fluid will remain in the turbine until power is needed by the power network, at which point condensed water will be produced. This is similar to the base Factorio Steam Turbine structure, which will not consume steam unless needed for power generation.

The Condenser Turbine technology also unlocks a recipe for condensing steam to water in a chemical plant, allowing you to save 165 degrees C waste steam produced by some recipes (however generating no power).
