Investigation of flow behaviour of homogeneous and heterogeneous ash slurries: fly and bottom ash Porici
Chára, Zdeněk ; Vlasák, Pavel ; Konfršt, Jiří
The flow behaviour of fly ash and bottom ash from fluidic combustion slurries was experimentally investigated for laminar, transitional and turbulent regimes with respect to the effect of solid concentration, particle size distribution and time and intensity of shearing in smooth stainless steel pipes of inner diameter of 26.8 and 36 mm. Volumetric concentration ranges from 20 to 32 %, slurry velocity reach value up to 5 m/s. It was demonstrated that turbulent shearing or addition of bottom ash results in the significant decrease of the apparent viscosity; also laminar/turbulent transition region was reached for lower flow velocity.
