Shell boilers - Part 1: General
1.1 General
This European Standard specifies design, construction, equipment, operational and water treatment requirements
drawn up with a view to ensuring the operating safety of new stationary shell boiler plants.
This European Standard includes the requirements for the prevention of over-heating and inadmissible over-
pressurisation.
1.2 Boiler plants
A boiler plant consists of:
a) the shell boiler including all pressure parts from the feedwater inlet (including the inlet valve) to the steam
and/or hot-water outlet (including the outlet valve). This includes economisers, superheaters and associated
connecting pipes which are heated by flue gas and are not separated from the main system by intervening
shut-off devices. Also included is any piping connecting the boiler to and including the first isolating valve;
b) isolated economisers, superheaters and associated connecting pipes;
c) expansion vessels and/or expansion tanks for plants for hot water production;
d) thermal insulation and/or refractory and cladding;
e) installations for heat supply and heating;
f) installations for processing and feeding the fuel into the boiler;
g) installations for the air supply of the boiler including the fans;
h) installations for the feedwater supply of the boiler;
i) all control and safety systems.
This European Standard specifies requirements for both directly fired and electrically heated boilers including low
pressure boilers (LPB, see 3.7) as well as for waste-heat boilers with a gas-side pressure not exceeding 0,5 bar1)
of cylindrical design, constructed from carbon or carbon manganese steels by fusion welding and a design pressure
not exceeding 40 bar1). The boilers covered by this European Standard are intended for land use for providing steam
or hot water (typical examples are shown in Figures 1.2-1 to 1.2-5).
Großwasserraumkessel - Teil 1: Allgemeines
Diese Norm regelt die Konstruktion und Berechnung, die Ausrüstung sowie die Anforderungen an den Betrieb und die Wasserqualität im Hinblick auf die Sicherstellung der Betriebssicherheit neuer stationärer Großwasserraumkessel-Anlagen und in Übereinstimmung mit den grundlegenden Anforderungen der Europäischen Richtlinie über Druckgeräte. Diese Norm schließt die Anforderungen zur Vermeidung einer Überhitzung und Druckküberschreitung ein.
Chaudières à tubes de fumée - Partie 1: Généralités
1.1 Généralités
La présente norme européenne spécifie la conception, la fabrication, l'équipement, les prescriptions de fonctionnement et de traitement de l'eau dans le but de garantir un fonctionnement sûr des chaufferies équipées de chaudières à tubes de fumée neuves.
La présente norme européenne inclut les prescriptions pour la prévention de la surchauffe et de la surpression inadmissible.
1.2 Chaufferies équipées de chaudière
Une chaufferie consiste-en :
a) la chaudière à tubes de fumée, y compris l'ensemble des parties sous pression, depuis la tubulure d'entrée d'eau d'alimentation (incluant la robinetterie d'entrée) jusqu'à et y compris la sortie de vapeur et/ou d'eau surchauffée (incluant la robinetterie de sortie). Cela comprend les économiseurs, les surchauffeurs et les tuyauteries de liaison associées qui sont chauffés par les fumées et qui ne sont pas séparés du système principal par l'intervention d'un robinet de sectionnement. Sont également incluses toutes les tuyauteries de raccordement de la chaudière, y compris le premier robinet d'isolement ;
b) les économiseurs isolés, les surchauffeurs et les tuyauteries de liaison associées ;
c) les vases et/ou réservoirs d'expansion pour les installations de production d'eau surchauffée ;
d) les isolations thermiques et/ou réfractaires et placages ;
e) les installations d'alimentation en chaleur et de chauffe ;
f) les installations de préparation et d'alimentation en carburant de la chaudière ;
g) les installations d'alimentation en air de la chaudière, y compris les ventilateurs ;
h) les installations d'alimentation en eau de la chaudière ;
i) tous les systèmes de régulation et de sécurité.
