Product Name:Helical Screw Expanding Power Generator The Structures and Principle: A Screw Expander, the core of the technology, is one of the main parts of the Screw Expanding Power Generation system. In general, it consists of a pair of helical screws and the shell casing. Hot source (steam, hot liquid, or a mixture of both) moves first into groove A, which drives the twin helical screws in opposite directions. As the helical screw turns, groove position A moves toward position B, C, and D in order, and finally exit from groove E. During the period of the process, the hot source decreases in pressure and temperature, then expands (vaporization), meanwhile, power is produced by passing out of the unit via the main shaft from helical screw to generator. |
