Samenvatting:
The application of biomass for the generation of electricity is expectedto be realised at a larger scale within the coming years. Next to wood a wide
variety of different types of biomass are considered as a fuel for power
generating plants in the Netherlands. Information on the composition of
biofuels is not readily accessible. There is a need to increase and to
catalogue the available data. Also a method to evaluate differences within
one class of biomass and between different types of biomass is lacking. The
objectives of this study are to collect analysis data of different biomass
types and to develop a method for the evaluation of the analysis results. The
data are used for more general evaluations on the nutrient take-up and
accumulation in the willow samples and miscanthus samples, grown on various
test fields in Ireland. Also, the data served as input data for process
calculations and the evaluation of biomass gasification and combustion,
including pretreatment, handling and gas cleaning. Both subjects are
described in other reports of the project. In this report data are presented
in tables and in O/C - H/C diagrams in order to obtain a classification of
the different types of biomass fuels, to relate the different fuels and to
offer a quick method for controlling new analysis data. Within the framework
of the project a large number of samples were analyzed and, furthermore,
information on the chemical composition was collected from the literature.
Samples were analyzed for the presence of carbon, hydrogen, nitrogen,
sulphur, chlorine, fluorine, phosphorus, alkali-metals, earth-alkaline-metals
and heavy metals. All metals mentioned in the Dutch emission standard (BLA or
Directive Emissions Waste Incineration) were determined. Furthermore, the
moisture content, ash content, amount of volatile material and calorific
value were measured. 5 figs., 16 tabs.
