17、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 r
18、ight 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 procedur
19、es 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 r
20、ules 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 iden
21、tified 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.For an explanation

24、oody pellets Part 7: Graded non-woody briquettesiv ISO 2014 All rights reservedBS EN ISO 17225-7:2014ISO 17225-7:2014(E)IntroductionThe 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 o
25、f biofuels; to enable good understanding between seller and buyer as well as a tool for communication with equipment manufacturers. It will also facilitate authority permission procedures and reporting.This part of ISO 17225 supports the use of graded non-woody pellets for residential, small commerc
26、ial and public building applications.The residential, small 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 is not generally managed by professional heati
27、ng engineers Appliances are often located in residential and populated districtsNon-woody briquettes have high ash, chlorine, nitrogen, sulfur and major element contents, so non-woody briquettes are recommended to be used in appliances, which are specially designed or adjusted for this kind of briqu
28、ettes.NOTE 1 Briquettes produced according to this part of ISO 17225 may be used in stoves, fireplaces, cookers, roomheaters and multifired sauna stoves, which are tested according to European standards EN 132291, EN 128152, EN 128093, EN 132404, EN 152505and EN 158216, and boilers systems tested ac
29、cording to EN 30357.NOTE 2 When using non-woody materials for combustion special attention should be paid to the risk of corrosion in small and medium scale boilers and flue gas systems. Be aware that herbaceous or fruit biomass may influence the fuel ash composition differently depending on growth
30、and soil conditions. The content of chlorine, phosphate and potassium in the material may form chlorides and phosphates and other chemical compounds resulting in high hydrochloric emissions and chemically active ash with low melting temperature causing corrosion.NOTE 3 In general non-woody biomass m
31、aterials have higher content of ash forming elements and produces ashes with lower melting temperature compared to most woody biomass. This may result in fouling, slagging and corrosion inside boilers. These problems are especially related to materials that contain high content of potassium (K) and
32、silicate (Si) and low content of calcium (Ca).NOTE 4 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-
33、1 in conjunction with these standards.

34、briquettes. This part of ISO 17225 covers only non-woody briquettes produced from the following raw materials (see ISO 17225-1, Table 1): 2 Herbaceous biomassNOTE 1 Herbaceous biomass is from plants that have a non-woody stem and which die back at the end of the growing season. It includes grains or
35、 seeds crops from food production or processing industry and their by-products such as cereals. 3 Fruit biomass 4 Aquatic biomass 5 Biomass blends and mixturesNOTE 2 Group 5 Blends and mixtures include blends and mixtures from the main origin-based solid biofuel groups woody, herbaceous biomass, fru
36、it biomass and aquatic biomass.Blends are intentionally mixed biofuels, whereas mixtures are unintentionally mixed biofuels. The origin of the blend and mixture is to be described using ISO 17225-1, Table 1.If solid biofuel blend or mixture contains chemically treated material it shall be stated.NOT
37、E 3 Thermally treated biomass briquettes (e.g. torrefied briquettes) are not included in the scope of this part of ISO 17225. Torrefaction is a mild pre-treatment of biomass at a temperature between 200 300 C.2 Normative referencesThe following documents, in whole or in part, are normatively referen
