Characterization of coal water slurry prepared for PRB coal

Journal of Fuel Chemistry and Technology, 2014
Abstract Powder River Basin (PRB) coal, which accounts for over 40% of the coal consumed for power generation in the United States, was investigated for preparation of coal water slurry (CWS). The static stability and rheology of the CWS were characterized as a function of loading.

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 (

The effect of coal properties on the viscosity of coal–water slurries

Fuel, 2002
Abstract Studies on coal–water slurries (CWSs) have been conducted for many years to replace fuel oil. In this research project, the effect of coal properties on CWSs have been investigated using two Turkish coals of different ranks and a Siberian bituminous coal. Physical, chemical and surface properties of coal samples were determined. Furthermore,

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,

Water Requirement for Coal Slurry Transportation

1983
Abstract: The amount of water required for coal slurry transportation is a function of the coal properties and the magnitude of coal movement. The pipeline system characteristics and the method of slurry preparation also affects the overall water requirement of the system.

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.
