Turbine expanders.

Turbine expander

The expander is a device used for additional gas cooling by means of its pressurized release into the cylinder with a piston moving with force. The gas performs an operation and gets cooled in the process.

In gas refrigerating machines along with the pressure reduction, the decrease in the refrigerant temperature occurs after the expander is applied. Any type of a combustion turbo generator running on gas differential pressure is also commonly referred to as an expander. Usually expanders are applied when overpressure is a byproduct and it should be somehow reduced for the further use of a working medium, i.e. gas.

Since there is almost no fuel consumption during the expander operation, the resulting energy is clean. Thus, the atmospheric emission of carbonic oxides is lowered.



Parameters of turbo expanders are:
Pressure : 0,3 8 MPa
Flow rate : up to 20 Million m3
Outlet fluid
content
: up to 20% (mass)
