Design and Build of Steam Compressor


Low quality waste steam is usually condensed before being returned to the boiler. Large quantities of heat energy are wasted into the environment.


In 2012, CET developed a 50kW steam turbo compressor. It was designed, with a two-stage configuration, to operate in a range of applications including mechanical vapour recompression (MVR), as a high temperature heat pump or as a low-pressure steam generator.


This unit underwent a 1000 hours client site endurance test.

A field trial was not conducted as development was focused on the Steam expander generator.

The project was subsequently cancelled when TPG D&T was dissolved.
