DIN EN ISO 17225-7:2014-09 IntroductionThe objective of the ISO 17225 series is to provide unambiguous and clear classification princi
27、ples 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. It will also facilitate authority permission procedures and reporting.This part of ISO 17225 su
28、pports the use of graded non-woody pellets for residential, small commercial 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 fl
29、ue gas cleaning Appliances is not generally managed by professional heating 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 ap
30、pliances, which are specially designed or adjusted for this kind of briquettes.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
31、 128093, EN 132404, EN 152505and EN 158216, and boilers systems tested according 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 biomas
32、s may influence the fuel ash composition differently depending on growth 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 me
33、lting temperature causing corrosion.NOTE 3 In general non-woody biomass materials 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 especi
34、ally related to materials that contain high content of potassium (K) and 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 a
35、nd supporting ISO 17225-1. It is recommended to obtain and use ISO 17225-1 in conjunction with these standards.EN ISO 17225-7:2014 (E) 4 DIN EN ISO 17225-7:2014-09 1 ScopeThis part of ISO 17225 determines the fuel quality classes and specifications of graded non-woody briquettes. This part of ISO 17
36、225 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 seeds crops from food producti
37、on 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, fruit biomass and aquatic biomass.
38、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.NOTE 3 Thermally treated biomass b
39、riquettes (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 referenced in this document and are in
