US7789618 B2 - Systems for moisture removal in steam turbine engines (Steven S. Burdgick & Frolov Boris Ivanovitch)


Bằng sáng chế US7789618 B2 - Systems for moisture removal in steam turbine engines - Hệ thống xử lý ẩm trong động cơ tuabin hơi (Steven S. Burdgick & Frolov Boris Ivanovitch).

A system in a steam turbine for removing water droplets from the flowpath of a steam turbine that may include a groove for collecting water droplets, and a plurality of moisture removal holes originating within the groove.

The groove may run in a circumferential manner around an outer sidewall of the steam turbine, be axially positioned upstream and in close proximity to the leading edge of a nozzle, and have a gradual slope at a leading edge and a steep wall at a trailing edge. The moisture removal holes may be a channel through the outer sidewall through which the water droplets that collect in the groove may flow.
