Guide for procurement of power station equipment - Part 6-7: Turbine auxiliaries - Moisture separator reheaters

This standard establishes technical specifications for heat exchangers equipped with dehumidifiers used in turbine equipment within power generation facilities. It addresses critical design, manufacturing, and performance requirements necessary to ensure the reliability and efficiency of these components in steam cycles. The document outlines parameters for material selection, structural integrity, and operational limits specific to equipment operating under high thermal and mechanical stress conditions. It provides guidance on testing methodologies to verify the effectiveness of moisture separation and heat transfer processes, which are essential for optimizing turbine output and preventing corrosion damage. The scope covers the integration of dehumidification systems into the broader thermodynamic cycle of a power plant, aiming to maintain water quality and protect downstream turbine blades. By adhering to the defined criteria, manufacturers and operators can achieve consistent performance levels that support the safe and sustainable operation of modern energy infrastructure. This normative guidance supports the harmonization of technical practices across the industry without specifying specific dates or originating bodies.
