Solid biofuels - Methods for the determination of moisture content - Oven dry method - Moisture in general analysis sample

BS DD CEN/TS 14774-3-2004 发布历史

This document describes the method of determining the moisture in the analysis sample by drying the sample in an oven. It is intended to be used for general analysis samples according to prCEN/TS 14780. The method described in this document is applicable to all solid biofuels. NOTE The term moisture content when used with biomass materials can be misleading since untreated biomass frequently contains varying amounts of volatile compounds (extractives) which may evaporate when determining the moisture content of the general analyses sample by oven drying. Since biofuels in small particle size are very hygroscopic, their moisture content will vary with change of humidity of the atmosphere and therefore, the moisture of the analyses sample should always be determined simultaneously when portions are weighed out for other analytical determinations, for example calorific value, carbon, nitrogen.
