Biocombustibles solides - Détermination de la distribution granulométrique des granulés désagrégés

La présente Norme européenne a pour objet de définir les exigences et la méthode utilisée pour déterminer la distribution granulométrique des granulés désagrégés. Elle est applicable aux granulés qui se désagrègent dans l’eau chaude à une température inférieure à 100 °C. Elle s’adresse aux fabricants, concepteurs, vendeurs, installateurs et utilisateurs de matériel, d’équipement, d’outils et d’usines complètes où sont utilisés ces granulés de combustible, ainsi qu’aux producteurs, acheteurs, vendeurs et utilisateurs de ces granulés, qu’il s’agisse d’individus ou d’organisations.

Trdna biogoriva - Ugotavljanje porazdelitve velikosti delcev razdrobljenih pelet

Cilj tega dokumenta je opredelitev zahtev in metod, ki se uporabljajo za ugotavljanje porazdelitve velikosti delcev razdrobljenih peletov. Uporablja se za pelete, ki se razdrobijo v vroči vodi pri temperaturi pod 100  C. Ta metoda se ne uporablja za npr. pelete, izdelane iz pražene surovine. Namenjena je osebam in organizacijam, ki proizvajajo, načrtujejo, prodajajo, sestavljajo ali uporabljajo stroje, opremo, orodja in celotne obrate, povezane z gorivnimi peleti, ter vsem osebam in organizacijam, ki so vključene v proizvodnjo, nabavo, prodajo in izkoriščanje gorivnih peletov.

SIST EN 16126:2012

EN 16126:2012 (E) 4 Introduction In coal power plants with powder fuel burners for energy production, rebuilt to use biomass powder from biofuel pellets, the operators need information on the particle size distribution in the fuel for optimising of e.g. efficiency and emission levels. The grinders used for producing fuel powder within these plants grinds the biomass pellets into the individual internal particles in the pellets. The method described in this document aims to estimate the internal particle size distribution of the material comprised in fuel pellets.

For the time being, this method is based on experience of pellets made from sawdust, wood shavings and milled wood or straw as raw material. The method may also be applicable for pellets produced from other biofuel materials. SIST EN 16126:2012
