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

32、tribution 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 ch
33、aracterize 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
34、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.5DIN
35、EN ISO 17830:2016-11 EN ISO 17830:2016 (E)1 ScopeThis 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 referencesThe following documen

The container shall be able to hold at least 2 000 ml of the deionised water and the entire te
41、st portion of pellets without spilling over during stirring.A lid or a cover, e.g. aluminium foil, shall be used to cover the container during the dissolving of the pellets in water.Volume of container should be about 5 l.6.2 Electric kettle or other suitable equipment for water heating, capable of
42、heating at least 2 000 ml of water.6.3 Drying cabinet or oven, shall be capable of maintaining a temperature of (60 5) C with at least three air exchanges per hour. The air velocity shall be such that the test sample particles are not dislodged from the drying container(s).NOTE Higher air exchange r
43、ates will shorten the drying time.6.4 Drying containers, shall consist of non-corrodible heat-resistant material such as metal, glass or porcelain and be able to hold sufficient volume to accommodate the slurry from the disintegration container.6.5 Balance, shall be capable of reading to the nearest
44、 0,01 g.6.6 Sieves, set of sieves described in ISO 17827-2 and listed in Table 1 shall be considered the default sieve set. However, other sieve sets can be used based on the specific requirements as agreed upon by the interested parties such as listed in Table 2.6.7 Weighing containers, an adequate
45、 number of weighing containers are required.The weighing of the sieved particle fractions can be performed either by weighing the remaining material directly on the tarred weighed sieves or by collecting and weighing the material in weighing containers.6.8 Spoon, shall be made of non-corrodible mate
46、rial for stirring the disintegration slurry.6.9 Mechanical sieving equipment, sieving equipment in accordance with ISO 17827-2 shall be used for determination of the particle size distribution of the disintegrated pellets and to break down agglomerates of particles formed during the drying of the sl
47、urry.Some sieving machines have adjustable parameters. The results of the sieving might differ depending on how adjustable parameters are controlled. It is therefore important, for comparative purposes, to report how the adjustable parameters have set in terms of frequency, amplitude, duration, etc.
48、 If machines have adjustable dimensionless settings, an estimate of the adjustable degree shall be recorded to the best of the ability of the operator.6.10 Flat surfaced tool, or flat brush, shall be used for stirring the dried material and for separating agglomerated particles after drying and siev
