Characterisation of Feedstocks - D6 Final Report (Phase 1) - Appendix 10 - Part 1: Willow SRC study 1 graphs

This document describes the characteristics of Willow SRC in terms of moisture content, net and gross calorific value, dry ash content and its variability, dry nitrogen content, dry chlorine, barium, beryllium, chromium, cobalt, copper, molybdenum, nickel, vanadium, zinc, arsenic, antimony, mercury, cadmium, lead, fluorine, bromine, aluminium, calcium, iron, potassium, manganese, sodium, phosphorus, silicon and titanium content. This document is one of the 13 appendices to the Final Report from the first Phase (2015/16) of the Characterisation of Feedstocks (CofF) project, the primary purpose of which is to provide an understanding of UK produced biomass properties, how these vary and what causes this variability. The purpose of this report plus its related parts is to report the variability in feedstock properties of UK produced energy biomass, the causes of these variations and the relationship between the feedstock properties and the provenance data collected. Five feedstocks were studied: Miscanthus, willow short rotation coppice (SRC), poplar SRC, poplar grown as short rotation forests (SRF), and spruce SRF, with poplar and Sitka spruce selected to represent broadleaved and coniferous biomass crops respectively. Provenance data include site properties (such as general climate zone and soil chemistry), the conditions at the time of sample collection, and past management of the site and crop with soil samples also collected for analysis. The feedstock samples were analysed in UKAS accredited laboratories.

本文件阐述了柳树短轮伐期矮林（Willow SRC）的各项特性，包括含水率、净热值与总热值、干灰分含量及其变异性、干基氮含量，以及干基氯、钡、铍、铬、钴、铜、钼、镍、钒、锌、砷、锑、汞、镉、铅、氟、溴、铝、钙、铁、钾、锰、钠、磷、硅与钛的含量。
本文件为《原料特性表征（Characterisation of Feedstocks，简称CofF）项目第一阶段（2015/2016年）最终报告》的13份附录之一。该项目的核心目标是阐明英国本土生产的生物质原料的各项属性、其波动规律及波动成因。
本报告及其相关附件的撰写目的，在于梳理英国本土生产的能源生物质原料属性的波动情况、波动成因，以及原料属性与所采集的溯源数据之间的关联。
本次研究共涉及5种原料：芒草、柳树短轮伐期矮林（SRC）、杨树短轮伐期矮林、短轮伐期林分杨树（Short Rotation Forests，简称SRF）以及云杉短轮伐期林分；其中选取杨树与西加云杉（Sitka spruce）分别代表阔叶类与针叶类生物质作物。
溯源数据涵盖样地属性（如所属气候大区与土壤化学特性）、样品采集时的现场条件，以及样地与作物既往的经营管理情况，同时还采集了土壤样品用于配套分析。
所有原料样品均在英国认可服务（UK Accreditation Service，简称UKAS）认证的实验室中完成检测。
