固体生物燃料 体积密度的测定

[中文适用范围]： 本文件规定了一种使用标准测量容器测定固体生物燃料的体积密度的方法。该方法适用于所有可倾倒固体生物燃料，其标称顶部尺寸最大为 63 毫米，最大颗粒长度为 200 毫米。对于标称顶部尺寸大于 63 毫米的燃料，描述了一种不同的方法。体积密度不是绝对值；因此，必须标准化其测定条件才能获得比较测量结果。注意：固体生物燃料的体积密度会因振动、冲击、压力、生物降解、干燥和润湿等多种因素而发生变化。因此，测量的体积密度可能与运输、储存或转运过程中的实际情况有所不同。 [外文原描述]： This document specifies a method for determining the bulk density of solid biofuels using a standardized measuring container. This method is applicable to all pourable solid biofuels with a nominal top size of maximum 63 mm while the maximum particle length is 200 mm. For fuels with a nominal top size larger than 63 mm, a different method is described. Bulk density is not an absolute value; therefore, conditions for its determination have to be standardized in order to gain comparative measuring results. NOTE Bulk density of solid biofuels is subject to variation due to several factors such as vibration, shock, pressure, biodegradation, drying, and wetting. Measured bulk density can therefore deviate from actual conditions during transportation, storage, or transhipment.
