Solid biofuels - Sampling 固体生物燃料 - 取样
发布日期: 2011-06-15
废止日期: 2017-04-26
本欧洲标准描述了制备取样计划和证书的方法,并采集固体生物燃料样品,例如从原料生长的地方,生产工厂,交货地等。货车负载或库存。它包括手动和机械方法,适用于以下固体生物燃料: - 细(粒径高达约10毫米)和使用勺子或管道进行采样的规则形状的颗粒材料,例如:锯屑,橄榄石和木颗粒; - 粗或不规则形状的颗粒材料,可以使用叉子或铲子进行采样的直径大约为200mm的颗粒,例如:木屑和坚果壳,森林残渣碎片和吸管; - 打包材料例如:捆扎草或草; - 手动或自动选择的大件(粒径大于200 mm) - 蔬菜废物,原始纸浆生产的纤维废料和已脱水纸浆的纸的生产; - 圆木。 在其他固体生物燃料上可能使用本标准。本欧洲标准中描述的方法可以用于例如当样品要测试含水量,灰分含量,发热量,堆积密度,耐久性,颗粒尺寸dist
This European Standard describes methods for preparing sampling plans and certificates and taking samples of solid biofuels, for example, from the place where the raw materials grow, from production plant, from deliveries e.g. lorry loads, or from stock. It includes both manual and mechanical methods, and is applicable to solid biofuels that are either: - fine (particle size up to about 10 mm) and regularly-shaped particulate materials that can be sampled using a scoop or pipe, for example: sawdust, olive stones and wood pellets; - coarse or irregularly-shaped particulate materials, particle sizes up to about 200 mm that can be sampled using a fork or shovel, for example: wood chips and nut shells, forest residue chips, and straw; - baled materials for example: baled straw or grass; - large pieces (particles sizes above 200 mm) which are either picked manually or automatically; - vegetable waste, fibrous waste from virgin pulp production and from production of paper from pulp that has been dewatered; - round wood. It may be possible to use this standard on other solid biofuels. The methods described in this European Standard may be used, for example, when the samples are to be tested for moisture content, ash content, calorific value, bulk density, durability, particle size distribution, ash melting behaviour and chemical composition. The methods are not intended for obtaining the very large samples required for the testing of bridging properties.
