Annotation.

The transition to water-coal fuel, declared in a government document, implies its transportation through pipelines, as well as using equipment of special high-tech complexes for preparing highly concentrated suspensions. This approach either eliminates the use of existing railways and requires the construction of pipelines of considerable length, or, while maintaining the delivery of coal to power plants through railway transport, there is a need to equip coal grinding complexes, mix it with water and homogenize the suspension. In both cases, alienation of land is necessary, as well as substantial capital and time costs.It is for the first time when it is proposed to use railway tanks for preparing water-based fuel, in which solid phase of the suspension is subject to soaking with the liquid phase and disintegrating under the action of grinding media directly during transportation by rail. In the article, within the framework of the considered technology for preparing water-based fuel, formulas are proposed for evaluating and justifying technological parameters for the process of preparing water-based fuel in a railway tank with grinding bodies, which imply the impregnation, disintegration and mixing of water-based fuel components during delivery to the consumer by rail. The dependences of the amplitude and frequency of vertical movement of material in the tank on the speed when they are transported along the railway tracks of the Dnieper region are established, preliminary waiting time of the tank after filling prior to shipment is justified, ensuring that the agglomerates are soaked before destruction, and the volumes of coal and water are mixed in the tank.

Keywords:

water coal fuel, tank car, rail transport, wagon vibrations.
