Chimneys - Thermal and fluid dynamic calculation methods - Part 1: Chimneys serving one combustion appliance

This European Standard specifies methods for the calculation of the thermal and fluid dynamic characteristics of chimneys serving one heating appliance.
The methods in this part of this European Standard are applicable to negative or positive pressure chimneys with wet or dry operating conditions. It is valid for chimneys with heating appliances for fuels subject to the knowledge of the flue gas characteristics which are needed for the calculation.
The methods in this part of this European Standard are applicable to chimneys with one inlet connected with one appliance. The methods in Part 2 of this European Standard are applicable to chimneys with multiple inlets and one inlet with multiple appliances. Part 3 describes methods for the development of diagrams and tables for chimneys serving one heating appliance.

Diese Europäische Norm legt wärme- und strömungstechnische Berechnungsverfahren von Abgasanlagen mit einer !Verbrennungseinrichtung" fest.
Diese Europäische Norm gilt sowohl für Unterdruck- als auch für Überdruckanlagen in feuchter und trockener Betriebsweise. Sie gilt für Abgasanlagen von !Verbrennungseinrichtungen" mit Brennstoffen, deren Abgaskennwerte, die für die Berechnung benötigt werden, bekannt sind.
Das Berechnungsverfahren dieser Europäischen Norm gilt für Abgasanlagen mit einem Anschluss für eine Verbrennungseinrichtung. Das Berechnungsverfahren nach Teil 2 dieser Europäischen Norm gilt dagegen für Abgasanlagen mit mehreren Anschlüssen und für einen Anschluss mit mehreren Verbrennungs-einrichtungen. Teil 3 beschreibt Verfahren zur Entwicklung von Diagrammen und Tabellen für Abgasanlagen mit einer !Verbrennungseinrichtung".

Conduits de fumée - Méthodes de calcul thermo-aéraulique - Partie 1: Conduits de fumée ne desservant qu'un seul appareil à combustion

La présente Norme européenne spécifie les méthodes de calcul des caractéristiques thermo-aérauliques des conduits de fumée ne desservant qu'un seul appareil.
Les méthodes données dans la présente partie de cette Norme européenne s'appliquent aux conduits de fumée fonctionnant sous pression négative ou positive, en ambiance humide ou sèche, et desservant des générateurs de chaleur utilisant des combustibles dont les caractéristiques des fumées sont connues pour les calculs.
Les méthodes données dans la présente partie de cette Norme européenne s'appliquent aux conduits de fumée desservant un seul  appareil. Les méthodes données dans la partie 2 de la présente Norme européenne concernent les conduits de fumée desservant plusieurs appareils (conduit collectif ou cascade). La partie 3 décrit des méthodes qui permettent d'élaborer des abaques et des tableaux pour les conduits de fumée desservant un seul générateur de chaleur.

Dimniki - Računske metode termodinamike in dinamike fluidov - 1. del: Dimniki za eno ogrevalno napravo

Ta evropski standard določa računske metode termodinamike in dinamike fluidov v dimnikih za eno ogrevalno napravo.
Metode v tem delu tega evropskega standarda se uporabljajo za dimnike z negativnim ali pozitivnim tlakom v vlažnih ali suhih obratovalnih pogojih. Uporablja se za dimnike z grelnimi napravami na goriva, če poznamo značilnosti dinamike fluidov v dimnikih, ki so potrebne za izračun.
Metode v tem delu tega evropskega standarda se uporabljajo za dimnike z enim dovodom, povezanim z eno ogrevalno napravo. Metode v 2. delu tega evropskega standarda se uporabljajo za dimnike z več dovodi in enim dovodom, povezanim z več ogrevalnimi napravami. 3. del opisuje metode za razvoj diagramov in preglednic za dimnike za eno ogrevalno napravo.
