US4948335 A - Turbine moisture removal system (George J. Silvestri)


Bằng sáng chế US4948335 A - Turbine moisture removal system - Hệ thống xử lý ẩm cho tuabin (George J. Silvestri).

An apparatus and method for improving moisture extraction from a steam turbine incorporates a collection slot adjacent a last rotating stage of the turbine with the collection slot being vented outside the turbine by bores through the turbine wall.

Moisture removal is enhanced by the use of pumps connected to each of the bores for suctioning water from the collection slot. The pumps may be ejectors powered by subcooled water to minimize flashing potential. The suctioned moisture is returned to the system after passing to a condenser.
