Rheology of coal-water slurries

Solid Fuel Chemistry, 2009
The costs of preparation and burning of coal slurries, in particular, coal-water fuel (CWF), considerably exceed the cost of coal utilization according to the conventional technology. CWF technology projects suggest that additional expenditures will be compensated for by the profitability of their pipeline transport in the laminar regime.

Additives the panacea of coal water slurry

Materials Today: Proceedings, 2021
Abstract Indian high ash coal was used for the preparation of coal water slurry consisting of coarse and fine particles in the proper proportion. Four bimodal samples were prepared with the combination of four coarse fractions such as (212 µm–300 µm, 90 µm–300 µm, 150 µm–212 µm, 75 µm–150 µm) with fine fraction of (

Viscometry and Rheology of Coal Water Slurry

Fuel, 1986
Abstract This paper presents the results of a detailed experimental study on rheological behaviour of coal water slurry (CWS). In contrast to earlier rheological studies at shear rates of rather narrow ranges, this study covered a much wider range of shear rates: 0–800 s −1 in a rotational viscometer and 400–10000 s −1 in a capillary viscometer ...

Performance Study of Coal Water Slurry

Applied Mechanics and Materials, 2014
This paper is based on the research of the coal water slurry rheological property and stability. The influence of the concentration, additives and temperature on the rheological properties of the slurry has also been studied. The apparent viscosity increases with increasing concentration of coal water slurry, and decreases with increasing temperature ...

Breakage Characteristics of Coal−Water Slurries

Energy & Fuels, 1996
Grinding tests were conducted under various conditions to characterize the breakage characteristics of coal-water mixtures. Five bituminous coals were ground in a conventional tumbling ball mill for different times at solids concentrations of 40-70% by weight, with and without the use of a dispersant.

Rheological Behavior of Coal-Water Slurry

Energy Sources, 2002
The rheological behavior of some Indian coal-water slurry (CWS) was investigated using a HAAKE RV30 viscometer. The objective was to study the effect of solid concentration, ash content, pH, and temperature on the rheology of CWS. It was found that CWS exhibits pseudoplastic behavior. The apparent viscosity varies with the amount of coal in the slurry,

The mechanism of combustion of coal-water slurries

Symposium (International) on Combustion, 1985
The combustion of coal-water slurries has been investigated using suspended and falling droplet techniques. Measurements have eeen made of ignition delays, mass loss and temperature rise for a range of coals with differing coal particle sizes and slurry preheat temperatures.
