Stabilization of coal-water suspensions

In this paper, the effect of sodium lignosulfonate and sodium carboxymethyl cellulose on the stability of a water-coal suspension was studied. As a result, the viscosity of the water-coal suspension was 0.01-0.08 P∙s. The change in dynamic shear rate was considered when adding these plasticizers in different changes. The minimum value of the dynamic shear rate of 13.6 was achieved with the addition of sodium LST plasticizer (SD = 0.1%) in the presence of 40% coal. The influence of alkali on the viscosity of a water-coal suspension was also studied.

Application of Water-Based Fuel in Heat Power Engineering

This article is devoted to obtaining a water-coal suspension with new technological properties. The article describes the technology of obtaining a water-emulsion suspension with the help of the Uzgen coal basin of the Karadobo deposit in the Osh region of the Kyrgyz Republic. Briefly, it is conventionally classified as a specific liquid-phase composite material with broad functional and technological capabilities.

Water-Coal Suspension Preparation Using Electrohydraulic Coal Breakage Method

This paper presents the results of an investigation into obtaining water-coal suspension from brown coals of Kansk-Achinsk basin using the electrohydraulic method. The obtained results are the basis for developing the technology of obtaining water-coal suspension using electrohydraulic crushing.

Numerical Simulation of Coal Suspension Sedimentation

The article describes the feasibility of numerical simulation of sedimentation process of coal suspension, with high concentration, using the Ansys Fluent package, with the assumption monodisperse grain composition of the disperse phase of the suspension. The analysis contains selection of computational model, determine the parameters for analysis and comparison of the results with laboratory tests. To comparison laboratory measurement and numerical simulation sedimentation test was used. In the analysis was used suspension from the coal purification process.
