Abstract:
The influence of fine fuel particles on deposition behavior is examined in a lab-scale experiment using a heatpipe probe positioned in the flue gas channel of a fluidizing bed combustor. A water cooling system assures isothermal conditions on the probe, leading to slagging due to hot particles’ stickiness on cold surfaces. An extra inlet for a defined fuel fine particle fraction above the fluidized bed allows controlled combustion in the freeboard area. Hereinafter, fine particles’ influence on over-all deposition behavior is measured and quantified through gravimetric analysis. This paper describes the experimental setup, the fuel used and presents the results of a series of measurements after 8 hours of operation with varying fractions of wood fine particles in range up to 12 kWth, showing significantly higher amount of depositions in presence of additional fine particles.
