Abstract:
A method for processing coal water slurry is provided and comprises: providing a first stream of coal water slurry comprising coal particles of a first average size; providing a first stream of additive; and processing the first stream of coal water slurry and the first stream of additive to produce a second stream of coal water slurry comprising coal particles of a second average size smaller than the first average size. An associated apparatus and system are also presented.
Abstract:
Es wird eine Vorrichtung und ein Verfahren zum Beschicken von Verarbeitungsanlagen, insbesondere Verbrennungsöfen (1) gezeigt, bei dem ein fließfähiges Verarbeitungsgut (3), das neben Flüssigkeitsanteilen (5) auch Festanteile (6) aufweist, in die Verarbeitungsanlage (1) über eine Förderleitung (2) druckbeaufschlagt eingebracht wird. Um vorteilhafte Beschickungsbedingungen zu schaffen, wird vorgeschlagen, dass das Verarbeitungsgut (3) vor der Druckbeaufschlagung gemischt wird.
Abstract:
The invention relates to the transportation and preparation for combustion of coal used as a solid fuel at heat power plants and can find applications in coal-based power generation. The object of the invention is a complex use of energy resources contained in coal, reduction of power consumption for the realization of the process, expansion of solid fuel pipeline transport application in coal-based power generation, increase in the coal pipeline operation safety, and the environment protection. Prior to the transportation via a pipeline, the initial stream of coal is screened into coarse material and fines, the latter being pressed into cylindrical monolithic blocks. Coal is transported via a pipeline filled with aqueous salt solution with a density exceeding that of the transported material, the coarse coal and pressed blocks being loaded into the pipeline alternately. At the power station, the coal delivered in the aqueous salt solution is separated from the liquid carrier, rinsed with water, dried and ground with simultaneous capturing of released methane. The effluents of rinsing are evaporated by heat released at the condensation of the working medium of the power plant thermodynamic cycle. The remaining stripped solution is mixed with liquid medium separated from the coal and returned to the starting point of the process.
