Thermocompressor Refurbishment

Paper mills customarily have at least one thermocompressor.  The thermocompressor is the main component in a dryer drainage system and is often neglected in this very critical process.  Proper evaluation of minimum/maximum conditions can improve a thermocompressor’s operating efficiency and greatly impact the bottom line by saving high pressure steam.

Thermocompressors use high-pressure steam to entrain a low-pressure steam and discharge the mixture to an intermediate pressure.  The high-pressure steam is converted to velocity energy across a nozzle.  The high-velocity steam entrains a relatively low-velocity steam and accelerates it.  The combined mixture of steam then enters the diffusers which converts the velocity head back to pressure head.

By retrofitting the thermocompressor to reflect current operating conditions, high pressure steam consumption required to recompress or recycle blow-through steam can be effectively optimized.
