Abstract：

Shenhua　coal　is　difficult　to　form　slurry　of　high　concentration,　low　viscosity　for　its　strong　hydrophilicity.　Based　on　that,　coal　water　slurry　(CWS)　additive,　denoted　as　LS-A,　was　used　to　prepare　Shenhua　coal　blending　slurry　with　high　concentration,　and　then　the　slurry　ability,　rheological　characteristic　and　static　stability　of　LS-A　were　investigated.　The　results　show　that,　the　performances　of　CWS　were　improved　by　LS-A,　and　it　had　good　viscosity　reducing　effect.　The　slurry　concentration　could　reach　65.5%,　and　the　apparent　viscosity　is　smaller　than　1200　MPa·s　with　good　flow　property　under　100　s　-1　of　shearing　rate　when　the　dosage　of　LS-A　was　0.7%.　The　rheological　investigation　indicated　that　the　slurry　pumped　with　LS-A　is　pseudoplastic　fluid,　and　it　had　rheological　property　of　shear-thinning,　evident　thixotropic　property　and　good　stability.　Moreover,　the　comparison　of　pulping　properties　and　stability　between　LS-A　and　the　additive　SPHF-3　of　National　CWS　Center　showed　that,　the　slurry　ability　was　similar　under　same　additive　dosage.　©　2011　IEEE.
