ABSTRACT:
In the past few years the use of biomass in power plants
has grown dramatically. As a result of this action fouling
and slagging in co-firing biomass facilities have turned out
to play a critical role in the efficiency of such facilities.
Efficient and effective methods are therefore needed to
control fouling to an acceptable level and to prevent
economic losses due to reduced furnace thermal efficiency,
increased maintenance or even unscheduled outages.
Numerical prediction of the impact of deposit properties has
proved itself to be a successful strategy to both evaluate
changes in the facility performance and to investigate
possible solutions to minimize fouling as well. TU Delft and
ECN started a project to monitor and control fouling in
furnaces co-firing biomass with coal by means of numerical
simulations and experiments. Numerical investigations are
based on the development of a novel in-house code to track
solid particles post-processing gas phase CFD data. These
have been calculated using commercial codes such as
FLUENT, CINAR and CFX. The Lagrangian Particle Post-
Processor code ( P3 ) strategy and numerical results are
presented here. Numerical simulation compare fairly well to
the available experimental data for glass particles.
