Abstract
Moisture separator configuration for separating water droplets from steam of a flow having a mixture of steam and water droplets, such that the cited flow travels through the moisture separator configuration so that this separation is achieved. The moisture separator configuration includes a plurality of plates oriented in line with the flow. The plurality of plates form channels through which the flow travels. The channels have progressive cross section variation along the flow direction, in order to collect progressively the water droplets separated from the steam in the flow.
Claims7
A moisture separator configuration for separating water droplets from steam of a flow having a mixture of the steam and the water droplets, such that the flow travels through the moisture separator configuration so that the separation of the water droplets from the steam is achieved, the moisture separator configuration comprising:
- a first plurality of plates oriented in line with the flow, wherein the first plurality of plates form channels through which the flow travels, the channels having progressive cross-section variation along the flow direction, in order to collect progressively the water droplets separated from the steam in the flow, wherein each one of the first plurality of plates includes a plurality of longitudinal grooves on one of its wall sides defining a plurality of drainage channels;
- and
- a second plurality of plates;
- wherein a first plate of the first plurality of plates includes a convex bend that protrudes into one of the channels through which the flow travels, towards an adjacent, second plate of the first plurality of plates;
- and
- a first plate of the second plurality of plates extends across the one of the channels towards the convex bend of the first plate of the first plurality of plates;
- wherein the Venturi channel is formed between the convex bend of the first plate of the first plurality of plates and a portion of the first plate of the second plurality of plates located adjacent to the convex bend;
- wherein the second plate of the first plurality of plates and the first plate of the second plurality of plates forms a first concave shaped cavity therebetween for entrapping small water droplets, for separating the small water droplets from the steam in the flow, and for preventing water film transportation on the non-impinging wall side;
- wherein each of the second plurality of plates includes a plurality of window openings forming a passage for the flow and inhibits vibrations in the moisture separator configuration.
A moisture separator configuration for separating water droplets from steam of a flow having a mixture of the steam and the water droplets, such that the flow travels through the moisture separator configuration so that the separation of the water droplets from the steam is achieved, the moisture separator configuration comprising:
- a first plurality of plates oriented in line with the flow, the first plurality of plates including at least a first plate and a second plate forming a flow channel therebetween, the first plate including a convex bend that extends into the flow channel towards the second plate;
- and
- a second plurality of plates, the second plurality of plates including at least a third plate extending from a point adjacent to the second plate across the flow channel towards an apex of the convex bend of the first plate;
- wherein the convex bend of the first plate and a portion of the third plate form a Venturi channel therebetween;
- wherein the second plate of the first plurality of plates and the third plate of the second plurality of plates forms a first concave shaped cavity therebetween;
- and
- wherein the third plate includes a plurality of window openings forming a passage for the flow and inhibiting vibrations in the moisture separator configuration, one window opening of the plurality of window openings being located in the concave shaped cavity.
