Solid biofuels - Fuel specifications and classes - Part 6: Non-woody pellets for non-industrial use

This European standard determines the fuel quality classes and specifications of non-woody pellets for non-industrial use. This European standard covers only non-woody pellets produced from the following raw material (see EN 14961-1:2010, Table 1):
-   2 Herbaceous biomass.
NOTE 1   Herbaceous biomass is from plants that have a non-woody stem and which die back at the end of the growing season. It includes grains or seeds crops from food processing industry and their by-products such as cereal straw:
-   3 Fruit biomass;
-   4 Biomass blends and mixtures.
NOTE 2   Group 4 Blends and mixtures include blends and mixtures from the main origin-based solid biofuel groups woody, herbaceous biomass and fruit biomass.
Blends are intentionally mixed biofuels, whereas mixtures are unintentionally mixed biofuels. The origin of the blend and mixture should be described using EN 14961-1:2010, Table 1.
If solid biofuel blend or mixture contains chemically treated material, it should be stated.

Feste Biobrennstoffe - Brennstoffspezifikationen und -klassen - Teil 6: Nicht-holzartige Pellets für nichtindustrielle Verwendung

Diese Europäische Norm legt die qualitätsbezogenen Brennstoffklassen und  spezifikationen für nicht-holzartige Pellets für nichtindustrielle Verwendung fest. Die vorliegende Europäische Norm umfasst nur nicht-holzartige Pellets, die aus folgenden Rohmaterialien hergestellt wurden (siehe EN 14961 1:2010, Tabelle 1):
-   2 halmgutartige Biomasse;
ANMERKUNG 1   Halmgutartige Biomasse stammt von Pflanzen mit einem nicht-holzartigen Stängel, die am Ende der Wachstumssaison absterben. Dazu gehören Getreide  oder Saatgutpflanzen aus der Lebensmittel verarbeitenden Industrie und deren Nebenprodukte, wie z. B. Getreidestroh.
-   3 Biomasse von Früchten;
-   4 definierte und undefinierte Mischungen von Biomasse.
ANMERKUNG 2   Gruppe 4 definierte und undefinierte Mischungen umfasst definierte und undefinierte Mischungen aus den auf der Herkunft beruhenden Hauptgruppen fester Biobrennstoffe holzartige Biomasse, halmgutartige Biomasse und Biomasse von Früchten.
Definierte Mischungen sind absichtlich gemischte Biobrennstoffe, während undefinierte Mischungen unabsichtlich gemischte Biobrennstoffe sind. Die Herkunft der definierten und undefinierten Mischungen sollte unter Anwendung von EN 14961 1:2010, Tabelle 1, beschrieben werden.
Wenn eine definierte oder undefinierte Mischung von festen Biobrennstoffen chemisch behandeltes Material enthält, sollte dies angegeben werden.

Biocombustibles solides - Classes et spécifications des combustibles - Partie 6: Granulés non ligneux à usage non industriel

La présente Norme européenne détermine les classes de qualité des combustibles et les spécifications des granulés non ligneux destinés à un usage non industriel. La présente Norme européenne ne couvre que les granulés non ligneux produits à partir des matières premières suivantes (voir l’EN 14961-1:2010, Tableau 1) :
-   2 biomasse herbacée ;
NOTE 1   La biomasse herbacée est extraite de plantes à tiges non ligneuses et se fanent à la fin de la saison de croissance. Elle inclut les graines ou les pédoncules provenant du secteur de la transformation alimentaire et leurs sous-produits, tels que les pailles de céréales :
-   3 biomasse fruitière ;
-   4 assortiments et mélanges de biomasses.
NOTE 2   Le groupe 4 Assortiments et mélanges comprend des assortiments et mélanges de biocombustibles solides issus des principaux groupes de biomasses ligneuse, herbacée et fruitière.
Les assortiments résultent du mélange intentionnel de différents biocombustibles tandis que les mélanges résultent d’une association non intentionnelle de différents biocombustibles. Il convient que l’origine de l'assortiment et du mélange soit décrite à l'aide du Tableau 1 de l'EN 14961-1:2010.
Si l’assortiment ou le mélange de biocombustibles solides contient des matériaux traités chimiquement, il convient de le mentionner.

Trdna biogoriva - Specifikacije goriv in razredi - 6. del: Nelesni peleti za neindustrijsko uporabo

Ta evropski standard določa kakovostne razrede goriva in specifikacije nelesnih peletov za neindustrijsko uporabo. Ta evropski standard zajema le nelesne pelete, izdelane iz naslednjih surovin (glejte preglednico 1 iz standard EN 14961-1:2010): – 2 zelnata biomasa; – 3 sadna biomasa; – 4 mešanice in zmesi iz biomase. Mešanice so namerno zmešana biogoriva, zmesi pa so nenamerno zmešana biogoriva. Poreklo mešanice in zmesi mora biti opisano na podlagi preglednice 1 iz standarda EN 14961-1:2010. Če mešanica ali zmes iz trdnega biogoriva vsebuje kemično obdelan material, je treba to navesti.

NOTE
In these product standards, non-industrial use means - fuel intended to be used in smaller appliances, such as in households and small commercial and public sector buildings. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United Kingdom. SIST EN 14961-6:2012

1) small-scale equipment does not usually have advanced controls and flue gas cleaning; 2) it is not generally managed by professional heating engineers; 3) they are often located in residential and populated districts. NOTE 1 Pellets produced according to this European Standard can be used in pellet burners tested according to EN 15270 and pellet boilers or integrated-pellet burner systems tested according to prEN 303-5 (< 500 kWth). NOTE 2 When using non-woody materials for combustion special attention should be paid to the risk of corrosion in small- and medium scale boilers and flue gas system. Be aware that for different types of herbaceous or fruit biomass growth under different conditions and soil type, may influence the fuel ash composition, e.g. in soil with a high phosphorus (P) content, potassium (K), that will capture chlorine (K will form K-phosphates instead of KCl) in the ash that will result in high hydrochloric emissions.
NOTE 3 In general non-woody biomass materials have higher content of ash forming elements and lower ash melting temperature compared to most wood based materials, which may result in slagging and deposit problems inside the boiler. These problems are especially related to materials that contain high content of potassium (K) and silicate (Si) and low content of calcium (Ca). SIST EN 14961-6:2012
