Saxlund Produces Electricity from Waste Heat

March 17, 2015 By Linda Hardesty

OpconSaxlund International will market and support a new, wet steam turbine (WST) power technology that produces electricity from saturated or superheated steam.

Developed by sister company Opcon Energy Systems around a twin screw Lysholm turbine, the Opcon Powerbox WST enables the production of between 200 kW–800 kW of electricity from low grade steam, which would not be possible in a traditional steam turbine, according to the company. The Powerbox WST replaces steam pressure reduction valves in existing process steam applications to produce electricity. Another application is the utilization of low-grade steam from industrial processes to generate energy instead of releasing it into the environment.

Saxlund says the technology is targeted to industrial plants where large amounts of steam are generated on-site for processes.

The Opcon Powerbox WST is available as a standalone skip mounted solution designed to run side-by-side with existing energy or process facilities to capitalize on waste heat. It can also be fully integrated within new industrial processes.

A number of installations are operating in Sweden and a new installation is being carried out this year as part of an E.ON district heating plant project.
