Overview

EN 45510-6-6:1999 (published by CLC) is a procurement guide for power station equipment, specifically covering turbine auxiliaries in the form of wet and wet/dry (hybrid) cooling towers and their internals. The standard provides practical guidance for preparing technical specifications when procuring natural-draught and mechanical-draught cooling towers for electricity generating stations. It explicitly excludes equipment intended for the nuclear reactor plant area of nuclear power stations.

Key identifiers:

• Standard: EN 45510-6-6:1999
• Organization: CLC
• ICS: 27.040 (Gas and steam turbines), 27.100 (Power stations in general)

Key Topics

This guide focuses on the content and structure of technical specifications rather than prescribing performance formulas. Core topics covered include:

• Water distribution system - guidance on specifying inlet, header and distribution requirements for cooling tower operation.
• Spray assembly - recommendations for specifying spray nozzles and spray systems used in wet and hybrid cooling towers.
• Filling (packing) - coverage of filling types such as film packing, splash grids or laths, and considerations for selection and procurement.
• Cooling tower internals - guidance on internal components and assemblies that affect thermal performance and maintainability.
• Scope and applicability notes - clarifies intended use in power stations and exclusions (nuclear reactor plant area).
• Support for procurement documents - structure and content suggestions for tender and contract specifications.

(The standard text includes additional internals and component topics; the above lists are representative of the main subject areas.)

Applications

EN 45510-6-6:1999 is practical for:

• Preparing detailed technical specifications and tender documents for wet and hybrid cooling towers.
• Defining procurement requirements for natural-draught and mechanical-draught cooling systems at thermal and combined-cycle power plants.
• Assisting in vendor evaluation and ensuring bids meet plant-specific functional and maintenance needs.
• Clarifying the scope of supply for cooling tower internals and water distribution systems.

Who Should Use This Standard

• Power plant design engineers and plant operators
• Procurement managers and purchasing teams
• EPC contractors and consulting engineers preparing tender documents
• Manufacturers and vendors of cooling towers and cooling-tower internals
• Asset owners specifying replacement or upgrade projects (non-nuclear areas)
