    A comprehensive three-dimensional (3D) numerical model is developed for simulation of entrained coal slurry gasifiers. In this model a presumed probability density function (PDF) method is used to consider turbulent effects on gas-phase reactions in the gasifier. A realizable k−ε model is adopted to predict turbulence information. Coal slurry particles are tracked with the Lagrangian method. West s coal an analysis of water use and environmental implications of coal­ slurry pipeline transport is presented. Simulations of a hypothetical slurry pipeline of 1000-mile length trans­ porting 12.5 million tons per year indicate that pipeline costs and energy requirements are quite sensitive to the coal-to-water ratio.

  • Coal slurryWikipedia

    Ideally coal slurry consists only of crushed coal and water which can be efficiently separated. In practice the separation is significantly costly due to the large amounts of water needed and wastewater generated by the process. Furthermore the slurry consists also of very fine coal dust that results in a waste called blackwater.As blackwater cannot be purified by a water treatment plant Coal-water slurry fuel is produced from coal which has a high content of volatile substances. It is delivered to an open platform then a front loader feeds it into a receiving hopper of a grinder. Coal can be ground by ball mills roller mills and hammer mills.

  • Effects of Coal Characteristics on the Properties of Coal

    ABSTRACT The effects of coal characteristics on the properties of coal water slurry (CWS) were systemically studied using sixteen Chinese coals of different ranks from lignite to anthracite. The correlation between coal properties and CWS characteristics were investigated by multivariate progressive regression analysis. CWS properties examined in this study included slurryability the slurry fuel (preferrably <1 ) and very fine particle size distribution (typically d 80 of 20-40µm). This is much finer than the conventional coal water slurry fuel (CWSF) for boilers or gasifiers.
