固体生物燃料.小规模应用的简化取样方法

[中文适用范围]： 本文件描述了在小规模应用和储存中采集固体生物燃料样品的简化方法，包括准备采样计划和报告。 主要关注≤100吨的仓储。 本文件适用于以下固体生物燃料： 1) 细小的（标称顶部尺寸最大约 10 毫米）和规则形状的颗粒材料，可以使用勺子或管道取样，例如锯末、橄榄石和木屑颗粒； 2) 可以使用叉子或铲子取样的粗糙或不规则形状的颗粒材料（标称顶部尺寸最大为 200 毫米），例如木片、生猪燃料和坚果壳； 3) 人工采摘的大块（标称顶部尺寸超过 200 毫米）（例如木柴和煤块）。 如果本文件中描述的程序适用，本文件也可用于上面未列出的其他固体生物燃料。 本文件规定了例如测试样品的水分含量、灰分含量、热值、堆积密度、机械耐久性、粒度分布、灰分熔化行为和化学成分时所使用的方法。 此外，它还描述了减少样本量的方法，并定义了样本处理和存储的要求。 注 1：如果需要更高精度的分析结果，或者当怀疑本文件是否适用时，可以使用 ISO 18135 中给出的公式估计分析结果。 注 2：颗粒本质上会产生 CO 和 CO2 废气。 如果对颗粒进行取样，请在取样之前和取样过程中检查容器、筒仓或棚屋等密闭空间中的 CO、CO2 和 O2 水平，并让另一个人在入口处待命。 [外文原描述]： This document describes simplified methods for taking samples of solid biofuels in small scale applications and storages including preparation of sampling plans and reports. The main focus is on storages with a size of ≤100 t. This document is applicable to the following solid biofuels: 1) fine (up to about 10 mm nominal top size) and regularly-shaped particulate materials that can be sampled using a scoop or pipe, e.g. sawdust, olive stones and wood pellets; 2) coarse or irregularly-shaped particulate materials (up to 200 mm nominal top size) that can be sampled using a fork or shovel, e.g. wood chips, hog fuel and nut shells; 3) large pieces (above 200 mm nominal top size) which are picked manually (e.g. firewood and briquettes). This document can also be used for other solid biofuels not listed above if the procedures described in this document are applicable. This document specifies methods to be used, for example, when a sample is to be tested for moisture content, ash content, calorific value, bulk density, mechanical durability, particle size distribution, ash melting behaviour and chemical composition. Additionally, it describes a method for the reduction of sample size and defines requirements on handling and storage of samples. NOTE 1 If higher precision of analytical results is needed or when in doubt if this document is applicable ISO 18135 can be used. Using the number of increments given in this document the resulting precision for analytical results can be estimated with the formulas given in ISO 18135. NOTE 2 Pellets can generate CO and CO 2 off gasses by nature. If pellets are sampled, check for CO and CO 2 and O 2 levels prior and during the sample taking process in a confined space like a container, silo or shed and have another person standby at the entrance.
