The Simulation and Water Quality Characterization of a Coal Slurry Involving Eastern Coal

, 1983
The water quality characteristics of a coal slurry were found to vary widely, depending upon the coal used and the use of a corrosion inhibitor. The coal-water interactions were evaluated in a pilot-plant closed-loop coal slurry pipeline. Pulverized coal

A coal-water slurry fueled internal combustion engine and method for operating same [PDF]

, 1992
An internal combustion engine fueled with a coal-water slurry is described. About 90 percent of the coal-water slurry charge utilized in the power cycle of the engine is directly injected into the main combustion chamber where it is ignited by a hot ...

Experimental research on low and strength characteristics of coal slime based cemented filling material

Meitan kexue jishu
To study the flow and strength characteristics of coal slime based backfill materials, orthogonal tests were used to design one cemented backfill material combining coal slime, high-water-content materials, cement, and fly ash.

Coal-CO[subscript 2] Slurry Feed for Pressurized Gasifiers: Slurry Preparation System Characterization and Economics

, 2013
Gasification-based plants with coal-CO[subscript 2] slurry feed are predicted to be more efficient than those with coal-water slurry feed. This is particularly true for high moisture, low rank coal such as lignite.

Carboxyalkylated Lignin as a Sustainable Dispersant for Coal Water Slurry

Polymers
Coal water slurry (CWS) has been considered a cleaner and sustainable alternative to coal. However, the challenging suspension of coal particles in CWS has created a major obstacle to its use in industry. This study presents a novel approach to enhance the stability and rheological properties of coal water slurry (CWS) through the utilization of ...

Atomization of Coal-Water Slurry Using a Pulse Combustor

, 1989
Preliminary experiments using a propane fired pulse combustor to atomize coal water slurry (CWS) have shown that the size distribution of the particles in the slurry can essentially be recovered by this atomization method.

Sand transport in multiphase pipelines [PDF]

, 2010
Over the life of an oil and gas reservoir, it is likely to encounter sand production. In offshore production fields, as there are lack of processing facilities nearby, gas, liquid and sand are often transported together in long distance pipelines.
