Since the 19th century, power plants have used steam turbines to generate clean energy. However, the technology has its limitations 鈥 the process is inherently inefficient and the presence of moisture in the system leads to premature wear and corrosion.

Steam screw expanders are positive displacement machines that allow power plants to run at slower speeds without the performance or safety issues of a conventional turbine. As a result, they broaden the possibilities for industrial power recovery and power generation.

With a steam screw expander, power plants can accept saturated, dry or overheated steam 鈥 and, when combined with an organic Rankine cycle (ORC) system, many types of gas as well. Steam screw expanders also help with decompression, cooling and other functions.

Using Our Steam Screw Expanders

A lol下注平台 Compressor screw expander generator can provide:

  • Pressure regulation in steam or gas pipelines
  • Power generation from flash steam and geothermal brine
  • Heat recovery and waste pressure recovery at low temperatures and low pressures

steam screw expanders are versatile pieces of equipment that work with co-generation, waste heat recovery and waste pressure recovery equipment. They are easy to install and maintain even in demanding operations.

The benefits of using a steam expander include reduced CO2 emissions, lower maintenance and less wear-and-tear on replaceable power system components.
