Overview

EN 45510-4-4:2002 - Guide for procurement of power station equipment, Part 4-4: Boiler auxiliaries - Fuel preparation equipment (CLC/CEN/CENELEC) is a procurement guide that helps purchasers write technical specifications for fuel preparation plant associated with steam generating and flue gas treatment plant in electricity generating stations. The Guide covers fuel preparation for solid, liquid and gaseous fuels and is written in performance-based terms to ensure correct equipment capacity, interfaces, reliability and safety. It is not applicable to equipment inside the nuclear reactor plant area of nuclear power stations.

Key topics and requirements

This standard focuses on specification content and evaluation rather than prescribing a single design. Core topics include:

• Scope of supply and terminal points - defining what the supplier delivers and the interface demarcations.
• Equipment types covered: feeders, pulverizers/mills, crushers, classifiers, fuel pipework (pulverised fuel, oil, gas), oil pumps, oil heaters, oil filters, dampers and valves.
• Operational requirements - operating environment, manning levels, normal/abnormal operation, start-up/shutdown and operating hours.
• Performance requirements - duty, performance margins, availability targets, redundancy levels and life expectancy/design life.
• Design and fabrication - material selection, safety features, interchangeability and fabrication methods.
• Maintenance and spares strategy - planned maintenance, access, lifting, special tools, test equipment and spare parts.
• Documentation and testing - tender/contract documentation, works tests, installation and commissioning tests, trial runs and performance verification.
• Quality, evaluation and compliance - evaluation criteria, inspection/approval procedures, non‑conformity handling and applicable legislation/standards.

These topics are intended to guide procurement teams toward robust, testable, and clear technical specifications that align with plant interfaces and regulatory requirements.

Applications and who uses this standard

EN 45510-4-4 is primarily used by:

• Procurement engineers and specification writers preparing tenders for boiler auxiliary and fuel preparation equipment.
• Plant owners / operators and utilities defining performance and availability targets for fuel handling systems.
• EPC contractors and OEMs responding to tenders and preparing design/fabrication documentation.
• Consultants and maintenance managers planning maintenance regimes, spare parts strategies and lifecycle costs.

Typical applications include specifying pulverizer systems, coal feeders, fuel oil systems (pumps/heaters/filters), fuel pipework and associated valves/dampers to ensure safe, reliable integration with boilers and flue gas treatment plant.

Related standards (if applicable)

EN 45510 Part 1 (Common Clauses) and other EN 45510 series documents (boilers, auxiliaries, turbines and electrical equipment) provide common procurement clauses and should be used together to form a complete specification framework for power station equipment procurement.

Guidance on the procurement of control and instrumentation systems for power stations, including advice oninterfaces can be found in EN 45510-8-1 (see Bibliography).4.6 Electrical supplies and other servicesThe specification should define the electrical supplies available for the operation of the equipment, theirvoltages and frequencies, with their range of variation, phases available and, where appropriate, theacceptable values of maximum load (kW) and short circuit level at each voltage level and the harmoniccontent. Requirements for terminals and terminal boxes should be stated; these should be to a recognisedEuropean or international standard.The specification should define the type and capacity of other services for the operation of the equipmentsuch as compressed air or auxiliary steam.4.7 Other interfacesThe specification should define the interfaces with existing ancillary or new ancillary equipment to besupplied under separate contracts which interact directly with the equipment, for example, civil works,cranage, or temporary systems.4.8 Project programmeThe specification should describe the overall programme and timescale in which the project is to be carriedout. This may include the principal dates associated with tendering, placement of orders, access to site, startand completion of installation, commissioning, take-over and final acceptance.4.9 Equipment identification systemsThe specification may specify the equipment identification system for use during the operating life of theplant. If applicable to the project, a recognised European or international system should be used.5 Extent of supplyThe specification should define the extent of supply of all the equipment.This could include for example:-main equipment such as coal feeders, mills, shut-off dampers, pipework, oil pumps, oil heaters, oilfilters, valves and, if appropriate, intermediate fuel storage equipment;-auxiliary equipment such as controls, instruments, power supplies, cooling and lubricating systems;-accessories for handling, maintenance or sampling systems;-spare parts such as mill grinding elements, pump seals, wear resisting liners;-site activities such as storage, transport and installation;-commissioning and performance tests;-documentation of equipment or system details, operation and maintenance manuals.If the purchaser wishes to have a contract for control and instrumentation separate from the equipmentsupply contract, the specification may require the supplier to provide information on all the necessaryinterfaces (e.g. all instrumentation tapping points and instruments, including their signal outputs, etc.,provided within the extent of supply).In addition provision may need to be made in the contract to ensure theavailability of information necessary to allow a satisfactory control system to be obtained. For example, thismay include a requirement for cooperation between the purchaser and supplier. Alternatively thespecification may define the technical information on equipment characteristics to be provided by thesupplier and the programme for its delivery.SIST EN 45510-4-4:2003

Performance tests are sometimes conducted off site and may be carried out at conditions different from theoperating point. The results may require scaling according to agreed rules. Where appropriate, correction curves shouldbe provided by the supplier to interpret tests which are not carried out at the defined operating condition.9.3 Equipment marginsThe specification should identify required equipment margins. These equipment margins may be appliedto compensate for uncertainty i
