Solid biofuels - Determination of particle size distribution of material within pellets (ISO 17830:2016)

This international standard describes the method for determination of the particle size of disintegrated pellets. The pellets
are disolved in water and dried after which the particles are sieved to determine the size of the particles constituting the
pellets.

Biocombustibles solides - Détermination de la distribution granulométrique des granulés désintégrés (ISO 17830:2016)

ISO 17830:2016 a pour objet de définir les exigences qui s'appliquent et la méthode utilisée pour déterminer la distribution granulométrique des granulés désintégrés. Elle est applicable aux granulés qui se désintègrent entièrement dans l'eau chaude.

Trdna biogoriva - Določevanje porazdelitve velikosti delcev peletiziranih materialov (ISO 17830:2016)

Ta mednarodni standard opisuje metodo za ugotavljanje velikosti delcev razdrobljenih peletov. Peleti se raztopijo v vodi in posušijo, nato pa se delci presejejo. Na podlagi tega je mogoče določiti velikost delcev, iz katerih so sestavljeni peleti.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

Introduction

In power plants with powder fuel burners for energy production, the operators need information

about the particle size distribution of the fuel for optimising particle burnout during combustion. Fuel

preparation equipment, such as pulverizers, are used for crushing pellets into the original particle sizes

before the material was pressed into pellets. The method described in this International Standard is

intended to characterize particle size distribution of the material contained within fuel pellets and also

allows for a relative comparison of pellets of different manufacturing.

This method is based on experience with pellets made from sawdust, wood shavings and milled wood,

as well as straw. The method may also be applicable for pellets produced from other solid biofuel

materials provided that they can be dissolved into its constituents in water.

Pellets that are engineered to resist water, e.g. pellets from materials which have undergone some

thermal treatments, cannot be characterised by this method.

Solid biofuels — Particle size distribution of
disintegrated pellets
1 Scope

This International Standard aims to define the requirements and method used to determine particle

size distribution of disintegrated pellets. It is applicable for pellets that fully disintegrate in hot water.

2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated

references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 16559 and the following apply.

3.1
sieve fraction
material collected on a sieve
4 Principle

The particle size distribution is determined after the sample pellets have been disintegrated in hot

deionised water and dried in a drying cabinet or oven. The determination is performed by sieving the

dried material in accordance with ISO 17827-2.
