标准范围

本文件描述了一种测定分级热处理和致密生物质燃料（如ISO/TS？17225-8中分类的生物质燃料）可磨性的方法，目的是制备具有规定粒度分布的燃料，以便在煤粉锅炉中有效燃烧。由试验方法确定的可磨性特征为使用此类燃料时的粉碎机性能提供了指导。除了ISO/TS 17225-8中所述的造粒材料外，该方法还可适用于ISO？17225-1:2021表14和表15中规定的非压缩或非致密热处理生物质。这种方法产生的结果与大型木屑无关，因为限制适用于大型磨煤机，通常不用于研磨木屑等材料。

This document describes a method for determination of grindability of graded thermally treated and densified biomass fuels such as classified in ISO/TS 17225-8, for the purpose of preparing fuels with a defined particle size distribution for effective combustion in pulverized fuel boilers. The grindability characteristics determined by the test method provide guidance as to the pulverizing mill performance when utilizing such fuels.Apart from pelletized materials as described in ISO/TS 17225-8, the method can also be applied to non-compressed or non-densified thermally treated biomass as specified in ISO 17225-1:2021, Table 14 and Table 15.The results created with this method are not relevant for large wood chips, since limitations apply for large pulverizing coal mills, which are typically not used for grinding materials such as chips.
