DIN EN ISO 17225-6:2014-09 IntroductionThe objective of the ISO 17225 series is to provide unambiguous and clear classification principles for solid biofuels and to serve as a tool to enable efficient trading of biofuels and to enable good understanding between seller and buyer as well as a tool
32、 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 commercial and public buildings as well as industrial energy generation applications, whic
33、h require classified pellet quality.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 are not generally managed by professional heati
34、ng engineers Appliances are often located in residential and populated districtsNon-woody pellets have high ash, chlorine, nitrogen and sulfur content and major element contents, so non-woody pellets are recommended to be used in appliances, which are specially designed or adjusted for this kind of
35、pellet.NOTE 1 Pellets produced according to this part of ISO 17225 may be used in pellet burners tested according to EN 152701and pellet boilers or integrated-pellet burner systems tested according to EN 30352.NOTE 2 When using non-woody materials for combustion special attention should be paid to t
36、he 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 and soil conditions. The content of chlorine, phosphate and potassium in the material may form chlorides and p
37、hosphates 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 materials have higher content of ash forming elements and produces ashes with lower melting temperature compare
38、d 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 silicate (Si) and low content of calcium (Ca).NOTE 4 For individual contracts ISO 17225-1 can be used.Although
39、 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 standardsEN ISO 17225-6:2014 (E) 4 DIN EN ISO 17225-6:2014-09 1 ScopeThis part of
40、ISO 17225 determines the fuel quality classes and specifications of graded non-woody pellets. This part of ISO 17225 covers only non-woody pellets produced from the following raw material (see ISO 17225-1, Table 1): 2 Herbaceous biomassNOTE 1 Herbaceous biomass is from plants that have a non-woody s
41、tem and which die back at the end of the growing season. It includes grains or 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
42、from the main origin-based solid biofuel groups woody, herbaceous biomass, fruit 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 biofue
43、l blend or mixture contains chemically treated material it shall be stated.NOTE 3 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-treatment of biomass at a temperature between 200 C to 300 C.2 Normative re
44、ferencesThe 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.
