Abstract

The article deals with the flow of highly concentrated water-coal fuel slurries (WCS) when they are added for the combustion through spraying devices – nozzles. The flow regimes of slurries in thin canals of spraying devices are studied. It is established that during the WCS flow through thin canals, the flow regime is violated, which is caused by the mutual influence of geometric dimensions and flow parameters of the slurries when it is burned in combustion chambers of power plants. Therefore, the design dimensions, especially the outlet diameters of the nozzle holes, must be selected, taking into account the obtained analytical expressions, which should be refined in carrying out model and full-scale experiments with specific types of WCS of constant composition
