Abstract
Abstract The apparatus includes a grid-like flow straightening means, a pressure reducer in the form of a perforated plate, and a separator for separating out the liquid. A wire mesh screen is also positioned between the pressure reducer plate and separator to provide an equalizing chamber for the steam leaving the plate.

Claim 3
Independent Claim
172 words
An apparatus for separating liquid from wet steam comprising a housing defining a flow path for wet steam and having an inlet for said wet steam, a first outlet for steam and a second outlet for liquid water; a planar grid disposed within said housing in said flow path, said planar grid including a plurality of transversely disposed flat sections defining chambers therebetween of a depth greater than the width thereof, each said chamber having an inlet opening exposed to said flow path for receiving a part of the wet steam; a pressure reducer downstream of said planar grid with respect to said flow path for equalizing the velocity distribution of the steam across said flow path, said pressure reducer being disposed across said chambers of said planar grid and including a plate in contact with said flat sections and having discrete perforations communicating with said chambers to throttle the flow therethrough; and a separator downstream of said pressure reducer for separating liquid from the steam in said flow path passing therethrough.
Claim 4
Independent Claim
172 words
An apparatus for separating liquid from wet steam comprising a housing defining a flow path for wet steam and having an inlet for said wet steam, a first outlet for steam and a second outlet for liquid water; a planar grid disposed within said housing in said flow path, said planar grid including a plurality of transversely disposed flat sections defining chambers therebetween of a depth greater than the width thereof, each said chamber having an inlet opening exposed to said flow path for receiving a part of the wet steam; a pressure reducer downstream of said planar grid with respect to said flow path for equalizing the velocity distribution of the steam across said flow path, said pressure reducer being disposed across said chambers of said planar grid and including a plate in contact with said flat sections and having discrete perforations communicating with said chambers to throttle the flow therethrough; and a separator downstream of said pressure reducer for separating liquid from the steam in said flow path passing therethrough.
Claim 5
Dependent Claim
48 words
An apparatus as set forth in claim 12 wherein said pressure reducer further includes a screen downstream of said plate, said screen having perforations of smaller size than said perforations in said plate to provide a lower pressure drop in the flow of wet steam than said plate.

Claim 13
Dependent Claim
33 words
An apparatus as set forth in claim 9 comprising a means for collecting separated liquid in said housing and a liquid discharge duct communicating with said means and said outlet for liquid water.
Claim 14
Independent Claim
155 words
An apparatus for separating liquid from wet steam comprising first means defining a flow path for a wet steam; a flow straightening means disposed within said first means in said flow path, said flow straightening means including a plurality of transversely disposed flat sections defining chambers therebetween of a depth greater than the width thereof; a flat shaped element having a plurality of discrete perforations in abutment with said flow straightening means on the downstream side thereof with respect to said flow path for equalizing the velocity distribution of the steam across Said flow path, said element being disposed across said chambers of said flow straightening means and having at least one of said discrete perforations communicating with a respective one of chambers to throttle the flow therethrough; and a plate-like separator of woven-fabric disposed across said flow path downstream of said element for separating liquid from the steam in said flow path passing therethrough.
