Abstract:
The second phase of a study on the technical feasibility of co-conversionof coal and biomass (waste) in IGCC (Integrated Gasification Combined Cycles)
systems based on entrained-flow gasification. Phase 1 consisted of a
preliminary desk study of IGCC systems and options for biomass
co-gasification, while Phase 2 comprised exploratory experimental work. The
objectives of Phase 2 have been (1) to assess the application of ECN's unique
concept for lab-scale simulation of full-scale entrained-flow gasification
conditions to biomass, (2) to characterise the conversion behaviour of
selected biomass fuels under entrained-flow gasification conditions, and (3)
to evaluate the experimental results with respect to full-scale operation and
to identify technical bottlenecks and further R and D needs. In Phase 1 an
overview of Dutch biomass (waste) streams potentially available for
co-gasification was given. From this, woody fuels were selected as an
interesting medium to long term secondary feedstock option for a dry-feed,
oxygen-blown entrained-flow gasifier, in particular the Shell gasifier of the
253 MW IGCC plant operated by Demkolec in Buggenum, Netherlands. As a
consequence, in this Phase 2 study Willow (energy crop) and Park wood
(biomass waste stream) were used as test fuels. 7 refs.
