Solid biofuels - Determination of grindability - Hardgrove type method for thermally treated biomass fuels (ISO/TS 21596:2021)

This document describes a method for determination of grindability of graded thermally treated and densified biomass fuels such as classified in ISO/TS 17225-8, for the purpose of preparing fuels with a defined particle size distribution for effective combustion in pulverized fuel boilers. The grindability characteristics determined by the test method provide guidance as to the pulverizing mill performance when utilizing such fuels.
Apart from pelletized materials as described in ISO/TS 17225-8, the method can also be applied to non-compressed or non-densified thermally treated biomass as specified in ISO 17225-1:2021, Table 14 and Table 15.
The results created with this method are not relevant for large wood chips, since limitations apply for large pulverizing coal mills, which are typically not used for grinding materials such as chips.

Biogene Festbrennstoffe - Bestimmung der Mahlbarkeit - Hardgrove-Verfahren für thermisch behandelte Brennstoffe aus Biomasse (ISO/TS 21596:2021)

Dieses Dokument beschreibt ein Verfahren zur Bestimmung der Mahlbarkeit von klassifizierten thermisch behandelten und gepressten Brennstoffen aus Biomasse, wie sie in ISO/TS 17225 8 klassifiziert werden, zur Herstellung von Brennstoffen mit einer festgelegten Partikelgrößenverteilung für eine wirksame Verbrennung in Heizkesseln für pulverisierte Brennstoffe. Die mit dem Prüfverfahren bestimmten Mahlbarkeitseigenschaften geben Hinweise auf das Leistungsverhalten der Pulverisiermühle bei der Verwendung derartiger Brennstoffe.
Neben pelletierten Materialien, wie in ISO/TS 17225 8 beschrieben, kann das Verfahren auch auf nicht gepresste thermisch behandelte Biomasse, wie in ISO 17225 1:2021, Tabelle 14 und Tabelle 15 festgelegt, angewendet werden.
Die mit diesem Verfahren erzielten Ergebnisse sind für große Holzhackschnitzel nicht relevant, da für große Kohlenstaubmühlen, die typischerweise nicht zur Zerkleinerung von Materialien wie z. B. Hackschnitzeln verwendet werden, Einschränkungen gelten.

Biocombustibles solides - Détermination de la broyabilité - Méthode de type Hardgrove pour les combustibles de biomasses traitées thermiquement (ISO/TS 21596:2021)

Le présent document décrit une méthode de détermination de la broyabilité des combustibles de biomasse traitée thermiquement et densifiée selon le classement donné dans l'ISO/TS 17225-8, dans le but de préparer des combustibles avec une distribution granulométrique définie pour une combustion efficace dans les chaudières à combustible pulvérisé. Les caractéristiques de broyabilité déterminées par la méthode d'essai fournissent des recommandations quant aux performances du broyeur-pulvérisateur lors de l'utilisation de tels combustibles.
Outre les matériaux sous forme de granulés décrits dans l'ISO/TS 17225-8, la méthode peut également être appliquée à de la biomasse traitée thermiquement non comprimée ou non densifiée décrite dans l'ISO 17225-1:2021, Tableaux 14 et 15.
Les résultats obtenus par cette méthode ne sont pas pertinents pour les gros copeaux de bois, car des limites s'appliquent aux grands broyeurs-pulvérisateurs à charbon, qui ne sont généralement pas utilisés pour le broyage de matériaux tels que les copeaux.

Trdna biogoriva - Določanje stopnje mletja - Metoda trdega grozda za toplotno obdelana goriva iz biomase (ISO/TS 21596:2021)

Ta dokument opisuje metodo za določanje stopnje mletja toplotno obdelanega in zgoščena goriva iz biomase, kot je razvrščeno v standardu ISO/TS 17225-8, za namene priprave goriv z opredeljeno porazdelitvijo velikosti delcev za učinkovito zgorevanje v kotlih na premogov prah.
Karakteristike stopnje mletja, določene s preskusno metodo, zagotavljajo smernice glede učinkovitosti delovanja stroja za drobljenje z uporabo takšnih goriv.
Poleg materialov v peletih, kot so opisani v standardu ISO/TS 17225-8, je mogoče metodo uporabiti tudi za nestisnjeno oz. nezgoščeno toplotno obdelano biomaso, kot je določeno v preglednicah 14 in 15 standarda ISO 17225-1.
Rezultati, ustvarjeni s to metodo, niso relevantni za velike lesne sekance, ker veljajo omejitve za velike mline za drobljenje premoga, ki se običajno ne uporabljajo za mletje materialov, kot so sekanci.
