Problems solved by technology

The heating tube group has gaps between adjacent heating tubes for the circulation of steam, but when the steam passes through the gaps, if the pressure loss is large, the cycle efficiency of the nuclear power plant will decrease

Embodiment Construction

[0045] Hereinafter, embodiments of the moisture separation heater of the present invention will be described with reference to the drawings. This embodiment will be described below by taking, as an example, a moisture separation heater installed in a power generation plant of a nuclear power plant. First, before describing the moisture separation heater, a power generation plant of a nuclear power plant equipped with the moisture separation heater will be briefly described. It should be noted that the materials, shapes, relative arrangements, and the like of components described in this embodiment are not intended to limit the scope of the present invention, but are merely illustrative examples.

[0046] Complete sets of power generation equipment for nuclear power plants 1 such as figure 1 As shown in the (schematic configuration diagram), the main steam 3 generated by the steam generator 2 performs work in the high-pressure turbine 4, becomes wet steam 5, flows out from the...

Abstract

The moisture separation heater has: a cylindrical casing extending horizontally with both ends blocked; a manifold chamber arranged in the casing and allowing steam to circulate along the axial direction of the casing; a separator arranged in inside the housing, and arranged along the manifold chamber in the length direction of the housing, to remove the moisture of the steam; On the downstream side of the steam, the heating tube group is formed into a polygonal shape in side view, the length direction slice of the heating tube group extends along the axial direction of the casing, and the width direction slice of the heating tube group extends along the extending vertically.

Description

technical field [0001] The present disclosure relates to a moisture separation heater for removing moisture from steam, and more particularly to a moisture separation heater suitable for use in nuclear power plants and the like. Background technique [0002] Conventional moisture separation heaters suitable for use in nuclear power plants, etc., such as those described in Patent Document 1, are provided on both sides in the width direction of a cylindrical casing extending in the horizontal direction and extend in the longitudinal direction of the casing. A pair of manifolds; arranged below each manifold, a pair of separators extending along the length of the shell and erected in the vertical direction; formed between the pair of separators, so that the steam passing through the pair of separators a gathered steam gathering part; and a heater arranged above the steam gathering part to heat the steam passing through the separator. [0003] In this conventional moisture separ...
