Waste Heat Recovery Twin Screw Expander Generator for Power Plant in India

Working Principle : 

A screw expander has spaces formed by a male rotor, female rotor, and casing. Each
actuation space has a pressure different from that of the others. Each rotor has surfaces,

each of which receives pressure caused by the pressure difference between the high-pressure

side and the low-pressure side after the expansion. The differential pressures cause rotation

torques to act on the respective rotors, causing them to rotate in opposite directions. The

rotations of the rotors isolate the actuation spaces from the air supply port. The actuation spaces
increase in volume as they proceed toward the exhaust side, expand the steam inside the enclosed
spaces and provide rotational energy to the rotors.The screw expander thus generates kinetic energy
through this continuous sequence of actions .
