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.

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.

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,

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.

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.
