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.

Study on the slurrying mechanism of coal water slurry prepared from coal gasification wastewater

The Canadian Journal of Chemical Engineering, 2023
Abstract The coal gasification process produces a large amount of wastewater which is seriously polluted and difficult to biochemically treat. The regasification of coal water slurry produced from gasification wastewater meets the requirements of clean and efficient use of energy and the concept of circular ...

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.

Structure of coal water slurry sprays

Journal of Propulsion and Power, 1995
A model of coal water slurry (CWS) sprays is presented with new experimental data for CWS viscosities and surface tension. The model is based on the aerodynamic theory of spray atomization that has been successfully used for diesel sprays. However, the higher CWS viscosity makes their behavior different from diesel sprays.

Combustion of coal-water slurry droplets

Fuel, 1986
Abstract The combustion of single droplets of coal-water slurries was studied experimentally by determining the instantaneous size and mass of the droplets and theoretically modelled for the char agglomerate by allowing for the presence of the ash layer as well as the residual volatiles.

Coal Water Slurry Fuels — An Overview

Mining, Metallurgy & Exploration, 1984
There are a number of incentives for potential users of coal slurry fuels--and in particular for coal-water mixtures (CWMs) which the authors address in this paper. First, CWM represents an assured supply of fuel at a price which is quite easily predictable into future years. Second CWM is available in the near term.

Atomization of Coal Water Slurry Sprays

SAE Technical Paper Series, 1994
<div class="htmlview paragraph">The atomization of coal water slurry (CWS) sprays is modeled using the aerodynamic theory of atomization. Several extensions to the theory have been explored to account for the non-Newtonian behavior of the slurry.

Modelling the Rheology of a Coal-Water Slurry

1991
A coal-water slurry (CWS) is a suspension of coal particles (up to 70% in weight) in water. A small amount of an appropriate chemical substance is added in order to fluidize the mixture which becomes stable against sedimentation and can be pumped through pipelines.
