摘要: Abstract Large amounts of municipal wastewater sludge (MWS) result in serious environmental problems and huge disposal investments. As a type biosolid with available calorific value, MWS can be directly combined coal, water, additives to produce coal–sludge slurry (CSS). Burning/gasifying this liquid fuel not only solves problems, but also maximizes the heat value sludge. In study, slurryability, rheology, thixotropy several CSSs were examined, effects type, mixing proportion ( α ), particle size on rheology thixotropic properties assessed. Compared coal–water slurry, behaved as more obvious pseudoplastic fluids considerable response, indicating that enhances pseudoplasticity slurry. The rheological behavior well fitted Herschel–Bulkley model so almost all correlation coefficients higher than 0.99. solid concentration increased, yield stress τ y consistency coefficient K increased; strengthened. reduction decreased apparent viscosity improved slurryability CSSs. experiment, fixed-viscosity increased by 1–2.5 percentage points. addition, study showed is positively correlated stability
