A moisture separator reheater including: • a pre-separator, and • a bottom wall surrounding the pre-separator, and wherein the pre-separator comprises: • a neck configured to allow steam flow through the neck, and • a wall configured to interact with the steam flow that is coming out of the neck, and wherein the neck is expanding in the direction of steam flowing through the neck, and the neck and the wall have substantially rotational symmetry, wherein the neck and the wall are separated by a space, wherein said space and the neck together form a pathway for the steam flowing through the neck, and the wall is concave towards the space, and characterized in that the moisture separator reheater further comprises: • one or more drains positioned about the bottom wall to drain moisture therein, and the pre-separator further comprises: • an internal baffle positioned in the space, wherein the internal baffle is convex towards the wall and is substantially rotational symmetric, and wherein said internal baffle is configured to split the steam flowing through the neck into two streams traveling along a first pathway and a second pathway, wherein the first pathway runs between the wall and the internal baffle and wherein the second pathway runs between the internal baffle and the neck, wherein the neck, the internal baffle, and the wall are configured to continuously change the direction of steam flowing along the first pathway so that the first pathway has a substantially curved shape that directs the steam out of pre-separator in the direction that is substantially perpendicular to the direction of the steam flow in the neck and towards the bottom wall to attach the steam to the bottom wall, and wherein the internal baffle and the neck are configured to continuously change the direction of steam flowing along the second pathway so that the second pathway has a substantially curved shape that directs the steam out of the pre-separator in the direction that is substantially perpendicular to the direction of the steam flow in the neck and towards said bottom wall to attach the steam to the bottom wall. • a pre-separator, and • a bottom wall surrounding the pre-separator, and wherein the pre-separator comprises: • a neck configured to allow steam flow through the neck, and • a wall configured to interact with the steam flow that is coming out of the neck, and • a neck configured to allow steam flow through the neck, and • a wall configured to interact with the steam flow that is coming out of the neck, and wherein the neck is expanding in the direction of steam flowing through the neck, and the neck and the wall have substantially rotational symmetry, wherein the neck and the wall are separated by a space, wherein said space and the neck together form a pathway for the steam flowing through the neck, and the wall is concave towards the space, and characterized in that the moisture separator reheater further comprises: • one or more drains positioned about the bottom wall to drain moisture therein, and • one or more drains positioned about the bottom wall to drain moisture therein, and the pre-separator further comprises: • an internal baffle positioned in the space, wherein the internal baffle is convex towards the wall and is substantially rotational symmetric, and • an internal baffle positioned in the space, wherein the internal baffle is convex towards the wall and is substantially rotational symmetric, and wherein said internal baffle is configured to split the steam flowing through the neck into two streams traveling along a first pathway and a second pathway, wherein the first pathway runs between the wall and the internal baffle and wherein the second pathway runs between the internal baffle and the neck, wherein the neck, the internal baffle, and the wall are configured to continuously change the direction of steam flowing along the first pathway so that the first pathway has a substantially curved shape that directs the steam out of pre-separator in the direction that is substantially perpendicular to the direction of the steam flow in the neck and towards the bottom wall to attach the steam to the bottom wall, and wherein the internal baffle and the neck are configured to continuously change the direction of steam flowing along the second pathway so that the second pathway has a substantially curved shape that directs the steam out of the pre-separator in the direction that is substantially perpendicular to the direction of the steam flow in the neck and towards said bottom wall to attach the steam to the bottom wall.
