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 ...

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.

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.

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.

Numerical Simulation of Coal Oil Water Slurry Gasification Process in New-Type Coal Water Slurry Gasifier

Applied Mechanics and Materials, 2012
The gasification process of coal oil water (COW) slurry in new-type coal water slurry(CWS) gasification furnace was studied with numerical simulation method. The temperature and concentration fields were obtained for the gasification furnace. The simulated results showed that the gasification effect of the new-type coal water slurry gasification is ...

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.

Developing anthracite coal water slurry fuel

Fuel and Energy Abstracts, 1996
Abstract : Public law has directed the Department of Defense (DOD) to increase the use of coal, particularly anthracite, at steam generating facilities. This study evaluates the feasibility of producing slurry fuel from anthracite coal and examines the combustion characteristics of the anthracite/water fuel slurry.

Effect of Coal Particle Size on Coal-Water Slurry (CWS) Atomization

Heat Transfer: Volume 2, 1997
Abstract The effect of coal particle size on coal-water slurry (CWS) atomization is examined by comparing classified CWS sprays containing coal particles in different size ranges. The sprays are generated by injecting a CWS mixture into a sonic air jet and the Malvern sizing system nonintrusively measures spray Sauter mean diameters (SMD)

Natural Dispersant in Coal Water Slurry Stabilization

2021
The stabilization of a coal-water slurry, which is a concentrated mixture of powdered coal and water, is popularly known as coal-water liquid fuel, and the maintenance of its suitable rheological characteristics necessitates the production of well-dispersed solid coal particles in water.

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 (
