Overview

EN 45510-4-5:2002 - Guide for procurement of power station equipment, Part 4-5: Boiler auxiliaries - Coal handling and bulk storage plant - is a CEN/CENELEC guidance document that helps purchasers prepare technical specifications for permanent coal handling and bulk storage equipment used with steam generating plant in power stations. The Guide emphasizes performance-based specification, correct interfacing, reliability, safety and compliance with European procurement practice. It does not apply to nuclear reactor plant areas, wharf infrastructure, or mobile site equipment.

Key topics and technical requirements

This Guide highlights the main elements to include when specifying coal handling and bulk storage plant. Major topics covered include:

• Scope of supply and terminal points (what the supplier must deliver and handover conditions)
• Equipment types: wagon unloaders/tipplers, ship/barge unloaders, stackers, reclaimers (bucket wheel/scraper), belt conveyors, bucket elevators, transfer towers, hoppers, silos, bunkers, screens, crushers, metal separators, sampling devices, weighers and shuttle/tripper conveyors
• Performance requirements: duty, throughput, equipment margins, availability, redundancy and verification of specified performance
• Design & fabrication: material selection, design justification, interchangeability and fabrication methods
• Operational requirements: operating environment, manning levels, start-up/shutdown, abnormal conditions, design life and components needing periodic maintenance
• Maintenance & spares strategy: planned maintenance, special tools, test equipment and spare parts policy
• Safety & access: personnel safety measures, access for maintenance, lifting requirements
• Documentation, testing and acceptance: contract documentation, works tests, installation and commissioning tests, trial runs and performance verification
• Quality & evaluation: evaluation criteria, inspections, approvals procedure, non-conformity handling
• Site factors & interfaces: access, site facilities and other interfacing plant and services

Practical applications and users

EN 45510-4-5 is used by:

• Procurement engineers and contract authors preparing technical specifications for coal handling systems
• Power station owners/operators and utilities defining performance and acceptance criteria
• EPC contractors, OEMs and suppliers responding to tenders for coal handling and bulk storage equipment
• Design consultants and plant engineers specifying interfaces, safety and maintenance provisions
• Quality and inspection teams arranging tests and approvals

This Guide streamlines the procurement of coal handling plant by defining clear technical, operational and testing requirements that ensure equipment integrates reliably with boilers and auxiliary systems.

This is the operating condition under which the performance tests areusually conducted3.2.5transfer towerjunction between successive belt conveyors. It houses the upstream conveyor head unit (headdrive pulley, motor drive unit) and downstream conveyor end unit (feed hopper, tail pulley,tension station)3.2.6belt conveyorequipment for the continuous conveyance of coal on a rubber belt with a trough section,supported by rollers and stretched between a head drive pulley and a tail pulley3.2.7trippermovable equipment on rails above a series of silos or bunkers, pouring down coal from thebelt conveyor to the silos or bunkersSIST EN 45510-4-5:2003

Attention is drawn to European, national and/or local legislation which can place restrictionsin this area.4.5Control and instrumentationThe specification should define the general requirements for the control and instrumentationsystem, the level of operator intervention allowed or required, integration with other controlsystems, localised control loops, commonality and redundancy.The specification should define the degree of automatic operation of certain parts of thesystem such as the coal stacker/reclaimer.NOTE
Guidance on the procurement of control and instrumentation systems for power stations,including advice on interfaces can be found in EN 45510-8-1 (see Bibliography).4.6Electrical supplies and other servicesThe specification should define the electrical supplies available for the operation of theequipment, their voltages and frequencies, with their range of variation, phases availableand, where appropriate, the acceptable values of maximum load (kW) and short circuit levelat each voltage level and the harmonic content.
