Steam Screw Expanders

Steam Screw Expanders

Recovering energy from a waste steam stream can offer many facilities the opportunity to reduce their overall environmental impact. Steam screw expanders can recover heat energy by converting low-, medium-, and high-temperature steam into electrical energy. With a steam screw expander, power plants can accept saturated, dry, or overheated steam. They can also be combined with our ORC systems to maximize overall thermal efficiency and recover the maximum amount of energy possible.

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 into smaller sizes for those with difficult steam conditions.

Kaishan steam screw expanders are versatile pieces of equipment that work as co-generation, waste heat recovery, and waste pressure recovery equipment. Common applications include:

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

Steam Screw Expander Benefits

• Low Capital Costs: We manufacture our products in an 85% vertically-integrated supply chain, providing our team with the opportunity to exercise industry-leading quality assurance protocols that both reduce the risk of failure and keep our costs down.
• High Efficiency: Kaishan steam screw expanders are engineered to maintain efficiency, even when dealing with unsteady steam conditions. These expanders are available in oil-free and lubricated configurations, both of which deliver high isentropic efficiency.
• Reduced CO2 Emissions: Kaishan steam screw expanders offer customers the ability to recover energy from waste steam or pressure reduction in an environmentally friendly way.
• Less Maintenance: Kaishan steam expanders are easy to install and maintain even in demanding operations. Our engineering team developed these expanders to experience less wear and tear on power system components for reliable, long-lasting performance.
