(>90%). It appears that screw expanders can work in relatively low power area, but are, actually, mainly adopted in a power range higher than the scroll or piston expander, due to manufacturing costs. Roots expanders are not frequently encountered. Technical and scientific literature about these machines is scarce.
EXPANDER-GEARBOX-GENERATOR. In most cases, the operating speed of the expander will be at a higher RPM than the operating speed of the generator. It is therefore necessary to utilize a speed reduction gearbox to facilitate appropriate coupling speed. In one such configuration, the high speed expander shaft is connected to a high speed coupling that transmits the torque to a speed reduction gearbox.
