Steam gathering system

Definition

A steam gathering system is a collection of pipelines and equipment designed to transport steam generated from geothermal resources to the power plant for electricity generation. This system plays a crucial role in flash steam power plants, where high-pressure steam is extracted from geothermal wells and directed to turbines for energy conversion. Efficient steam gathering systems are essential for optimizing the performance and reliability of geothermal power generation.
