27.100 - Power stations in general

This document specifies methods for measuring the quality of thermal power infrastructure (QTPI) during the operational phase and requirements for operations and management activities. It is intended for use by electric power providers, including public utilities and independent power producers (hereinafter collectively referred to as power plant operators), as well as relevant stakeholders that intend to maintain and improve QTPI. NOTE The selection and importance of evaluation indicators resul...view more

This document specifies requirements for the inspection during and after construction, documentation and marking of shell boilers as defined in EN 12953-1.
NOTE   For other components, such as water tube walls, reference will be made to the EN 12952 series.

This document gives general technical guidelines for evaluating energy savings of thermal power plants before and/or after implementing energy performance improvement action(s) (EPIAs). It includes evaluation, unit component efficiency, indexes calculation, analyses and reporting. This document is applicable to existing thermal power generating units (TPGUs), where fossil fuels (e.g. coal, oil, natural gas) are combusted to generate electricity only or to supply thermal energy with the additiona...view more

This European Standard specifies requirements for the workmanship and construction of shell boilers as defined in EN 12953-1.
NOTE 1   For other components such as water tube walls, see the EN 12952 series.
NOTE 2   For economizers and superheaters, see EN 12953-4 or EN 12952-5.

ISO 18888:2017 specifies standard rules for preparing, conducting, evaluating and reporting thermal performance tests on combined cycle and cogeneration power plants driven by gas turbines for base and part load operation with or without supplementary firing. ISO 18888:2017 is applicable to - thermal performance tests for general information, - thermal acceptance tests for determining the performance of the combined cycle plant in relation to a contractual guarantee, and - comparative tests desi...view more

This Part of this European Standard specifies requirements for the design and calculation of pressure parts of shell boilers as defined in EN 12953 1.
NOTE   For other components such as economisers, superheaters, tube walls, headers, reference should be made to EN 12952 series.

This part of IEC 61000 specifies EMC immunity requirements which apply to electrical and
electronic equipment intended for use in power stations and substations, as described below.
Immunity requirements for electromagnetic phenomena with spectral contributions in the
frequency range 0 Hz to 400 GHz are covered. No tests need to be performed at frequencies
or for phenomena where no requirements are specified.
This international standard sets immunity test requirements for equipment intended...view more

ISO 14084-1:2015 specifies types of process diagrams for power plants and rules and guidelines for the preparation and representation of information in such diagrams.

ISO 14084-2:2015 specifies graphical symbols for process diagrams for power plants and guidelines for creation of new graphical symbol examples. ISO 14084-2:2015 is a collective application standard of the ISO 14617‑series. Graphical symbols for fluid power diagrams can be found in ISO 1219‑1. Graphical symbols for electrotechnical diagrams can be found in IEC 60617.

This European Standard specifies the following materials for the pressure bearing parts of shell boilers and equipment of shell boilers (e.g. valves), subjected to internal and external pressure including integral attachments (non pressure bearing parts):
   flat products (plate) and parts formed from flat products (e.g. shell, furnace, dished ends);
   tubes and parts formed from tubes (e.g. bending, elbows, reducers, fittings);
   forgings and cast products ;
   bolting materials;

1.1   General
This European Standard applies to shell boilers with volumes in excess of 2 litres for the generation of steam and/or hot water at a maximum allowable pressure greater than 0,5 bar and with a temperature in excess of
110 °C.
The purpose of this European Standard is to ensure that the hazards associated with the operation of shell boilers are reduced to a minimum and that adequate protection is provided to contain the hazards that still prevail when the shell boiler is put into se...view more

IEC 60038:2009 specifies standard voltage values which are intended to serve as preferential values for the nominal voltage of electrical supply systems, and as reference values for equipment and system design. This seventh edition supersedes the sixth edition (1993), its Amendment 1 (1994) and its Amendment 2 (1997). It constitutes a technical revision. The significant technical changes are:
- the addition of the values of 230 V (50 Hz) and 230/400 V (60 Hz) to Table 1;
- the replacement of...view more

This part of this European Standard specifies the minimum requirements for safety related equipment for shell boilers as defined in EN 12953-1, to ensure the boiler operates within the allowable limits (pressure, temperature, etc.) and if the limits are exceeded the energy supply shall be interrupted and locked out without manual (human) intervention at the boiler.
NOTE 1   The maximum time of operation without manual (human) intervention should be defined for each boiler system.
NOTE 2   Annex C...view more
