摘要：
The effects of blending sewage sludge on the properties of coal-sludge slurry (CSS), such as solid loading, apparent viscosity, rheological behaviour and stability, were systematically investigated. The size and morphology of particles, and grinding efficiency were analyzed. The experimental results showed that adding sewage sludge can improve the grinding efficiency and stability of slurry. CSSs prepared from Yanzhou coal, Jiangxinzhou sewage sludge and Yangzi sewage sludge exhibit pseudo-plastic behaviour with an apparent viscosity decreasing with increasing shear rate. Both CSSs, containing 10 wt% Jiangxinzhou sewage sludge and 15 wt% Yangzi sewage sludge, with about 60 wt% solid loading and 1200 mPa s apparent viscosity, are suitable for theirs handling in preparation, transport, storage, atomization, and combustion processes.
