✦ Synopsis

Slurries of finely milled Eastern Canadian peat in No. 2 fuel oil were prepared and their flow characteristics studied by measuring viscosities, sedimentation (S.R.) and drain times as functions of per cent peat loading, peat moisture content, concentration of stabilizing additive, pH, and slurry blending and settlement times. The calorific values of the peat, fuel oil and peat-in-oil slurry were also measured. Good slurry stability was maintained at >40"/, peat loading, 15-30x peat moisture content, neutral pH, and 1% stabilizing additive concentration.

Good slurry stability was also maintained in the pOH range of -0.3 to -0.55 (2-3.5 M/l NaOH) and in the absence of a stabilizing additive. No synergistic effect was observed between the peat and fuel oil.
