Secondary breakup of coal water slurry drops

Physics of Fluids, 2011
To investigate secondary atomization of coal water slurry (CWS), deformation and breakup of eight kinds of CWS drops are presented using high speed digital camera. Based on morphology, deformation and breakup regimes of CWS drops can be termed some different modes: deformation, multimode breakup (including two sub-modes: hole breakup and tensile ...

Utilization Slurry Coal-Water Fuel

2014
The opportunity of technological and modified lignosulphonate wastes, process water, oxygenized brown coal with high content huminic acid (to 60 %) with alkali usage as plasticizer agent in the coal-water slurry (CWS) production technological process was checked. The CWS stability scheme in alkali additives interaction was suggested. The bituminous and

Polymeric dispersants for coal–water slurries

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2005
Abstract The effect of several low molecular weight polymers (MW  Good coal dispersants are also strong flotation depressants. The poor dispersing performance of hydroxypropyl cellulose correlates well with the inability of the polymer to depress the natural floatability of the bituminous coal.

Ultrasonic study of concentrated coal-water slurries

The Journal of the Acoustical Society of America, 1986
The use of ultrasonic absorption measurements as a diagnostic tool for monitoring the particle size of coal-water slurries has been suggested by M. C. Davis [J. Acoust. Soc. Am. 65, 387 (1979)]. The present paper reports some experimental data obtained from ultrasonic absorption and velocity measurements on electrostatically and sterically stabilized ...

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 ...

Coal-water slurry: A status report

Energy, 1986
Abstract During the years of oil shortage and rapidly increasing oil prices, the need to decrease dependence on oil-fired utility boilers became an urgent concern. The alternatives were to: 1. (1) build new coal-fired stations; 2. (2) modify oil-fired boilers to fire pulverized coal; 3.

Exporting Colorado Water in Coal Slurry Pipelines

Journal of Water Resources Planning and Management, 1985
The San Marco Pipeline Company has proposed a 1,000-mile (1,610-km) pipeline system to move coal slurry from southeastern Colorado to several electrical generating plants in the Texas Gulf Coast area. This area of Colorado is experiencing severe water shortage problems due to the large amount of water used for irrigation. Colorado statutes restrict the
