Characteristics of Coal Slurry Aggregate Induced by Inorganic Salts

Preparation of coal slurry with organic solvents.

In this study, various organic solvents were used to prepare coal slurries and the rheological and thermal properties of coal-organic solvent slurries were examined. Solvents with molecules containing unpaired electrons (high basicity) show high extraction power and cause swelling of coal. Therefore, coal-organic solvent slurries usually showed higher viscosities compared to coal-water slurry. ...

Preparation of coal slurry with 2-propanol.

This study explored the feasibility of using waste organic solvents as substitutes for water to prepare coal slurries. The rheological properties of coal-2-propanol slurries were examined and compared with that of coal-water slurry (CWS). The good compatibility between coal particles and 2-propanol resulted in stable particle suspension in slurry which usually exhibit Newtonian behaviour. Howev...

Design of Atomizers and Burners for Coal-water Slurry

A novel extensional viscometer was developed to measure the extensional properties of aqueous solutions of polymeric material and coal water slurries (CWS) containing additives. When a drop of viscoelastic liquid or CWS containing additives is allowed to form at the end of a capillary tube, it starts to fall once its weight exceeds the retaining force exerted by surface tension. In experiments ...
