The wet steam flow distribution section (20) of the moisture separator reheater (10) includes a multiplicity of side-by-side spaced-apart channel bars (52,54,56) extending transversely to the direction of steam flow from the distribution section to the moisture separator section (24). The bars are preferably substantially U-shaped in section, whereby the two leg portions (60,62) of each bar may be angled and slightly spaced apart from confronting leg portions of adjacent bars, thereby defining respective diffuser nozzles (64). Each nozzle has a discharge end cross-section elongated in the direction parallel to the bars, for directing wet steam toward the separator section. The spacing (Y) and other design variables associated with the bars, permit optimization and uniformity of flow over the full axial extent of the moisture separator reheater unit with minimum pressure drop across the steam distribution apparatus.
A moisture separator reheater comprising:
In a moisture separator reheater of the type having a wet steam flow distribution section upstream of a moisture separator section, the improvement comprising said flow distribution section including a multiplicity of side-by-side, spaced apart bars extending transversely to the direction of steam flow from the distribution section to the separator section, the bars defining a respective multiplicity of diffuser nozzles, each nozzle having a discharge end cross section elongated in the direction parallel to the bars, for directing wet steam toward the separator section.
