<p>For drying and superheating steam, particularly between the outlet of a high pressure turbine and to the inlet of a low pressure turbine, there is provided an elongated tubular pressure vessel disposed horizontally with a pair of end plates to generally close the same, a series of steam heaters arranged in the upper half of the vessel to extend axially with respect to the vessel with predetermined spacings between them for the passage therebetween of the steam to be heated, and a plurality of moisture separators or dryers each disposed in the lower half of the tubular pressure vessel at opposite ends of each of the steam heaters. Moisture laden steam exiting from a high pressure turbine will enter the pressure vessel at a plurality of steam inlets, each of which is provided at a position adjacent and leading to the plurality of moisture separators, respectively, and in the upper portion of the pressure vessel. After passage through the moisture separators, where the steam is dried, the steam will pass through the steam heaters to be discharged from the pressure vessel through steam outlets disposed near the central portion of each of the steam heaters. As the heating fluid for the steam heaters, live steam from a reactor may be employed or some of the steam extracted from the high pressure turbine may be employed.</p> |
