摘要： A steam generator is provided in which the total heat transfer efficiency can be improved by suppressing a reduction in the amount of heat exchange at an inlet side of heat transfer tubes while maintaining the effect of increasing the amount of heat exchange at an outlet side thereof. A steam generator includes a heat transfer tube group formed of a plurality of heat transfer tubes secured to a tube plate; an annular channel that is formed so as to cover the circumference of the heat transfer tube group and that has an opening for communicating with the heat transfer tube group at a lower portion thereof; a water supply box that is disposed at an upper portion of the annular channel and that supplies water to a cold-side portion of the heat transfer tubes; and a steam/water separator that is disposed above the heat transfer tube group and that separates water heated while passing from the annular passage along the circumference of the heat transfer tubes into steam and hot water, in which a porous plate for removing air bubbles is provided at an upper portion of the annular channel in the hot-side portion of the heat transfer tubes.

摘要： The present invention aims to decrease a pressure loss in a tube support plate 200 disposed in a steam generator, and ensure sufficient strength. The tube support plate 200 has many through-holes 100 formed therein for passage of heat transfer tubes 210. The shape of the through-hole 100 is a hexagonal shape. Protrusions 100a, 100b, 100c are formed in alternate sides 102, 104, 106 among the sides constituting the hexagonal shape. The arrangement of the through-holes 100 is a so-called honeycomb arrangement. Thus, the opening area of the through-hole 100 can be rendered large to decrease a pressure loss, and the strength of the tube support plate can be ensured.
