31、nThe objective of the ISO 17225 series is to provide unambiguous and clear classification principles for solid biofuels; to serve as a tool to enable efficient trading of biofuels; to enable good understanding between seller and buyer as well as a tool for communication with equipment manufacturers.
32、 It also facilitates authority permission procedures and reporting.This part of ISO 17225 supports the use of graded wood pellets for residential, small commercial and public buildings as well as industrial energy generation applications, which require classified pellet quality.The residential, smal
33、l commercial and public building applications require higher quality fuel for the following reasons: Small-scale equipment does not usually have advanced controls and flue gas cleaning. Appliances are not generally managed by professional heating engineers. Appliances are often located in residentia
34、l and populated districts.NOTE 1 Pellets produced according to this part of ISO 17225 may be used in pellet stoves, which are tested according to European Standard EN 147851, pellet burners tested according to EN 152702and pellet boilers or integrated-pellet burner systems tested according to EN 303
35、53.NOTE 2 For individual contracts, ISO 17225-1 can be used.Although these product standards may be obtained separately, they require a general understanding of the standards based on and supporting ISO 17225-1. It is recommended to obtain and use ISO 17225-1 in conjunction with these standards.EN I

This part of ISO 17225 covers only wood pellets produced from the following raw materials (see ISO 17225
37、-1, Table 1): 1.1 Forest, plantation and other virgin wood; 1.2 By-products and residues from wood processing industry; 1.3.1 Chemically untreated used wood.Thermally treated biomass pellets (e.g. torrefied pellets) are not included in the scope of this part of ISO 17225. Torrefaction is a mild pre-
38、treatment of biomass at a temperature between 200 C to 300 C.2 Normative referencesThe following referenced 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 referen

Pellets are usually
45、 manufactured in a die, with total moisture content usually less than 10 % of their mass on wet basis.Note 2 to entry: The woody biomass used as feedstock for pellet making is milled to size in accordance with customer specification. Determination of the particle size distribution of the constituent
46、s of pellets is done by ISO 17830.3.2additivematerial which has been intentionally introduced into the fuel feed stock to improve quality of fuel (e.g. combustion properties), to reduce emissions or to make production more efficientNote 1 to entry: Trace amounts of e.g. grease or other lubricants th
