Abstract: Heat processing of pulverized brown coal is carried out in two stages. In a chamber for the first-stage heating, brown coal to be processed is heated to a temperature of thermal decomposition thereof with the formation of a solid matter and a vapor and gas mixture. The resultant vapor and gas mixture is removed for purification and condensed to obtain gaseous and liquid products. In a chamber for the second-stage heating, brown coal, in the form of solid matter, is heated to cause additional decomposition thereof, which results in the formation of a solid product and a vapor and gas mixture. The resultant vapor and gas mixture, together with a part of the resultant solid product, is fed through a return conduit into the chamber for the first-stage heating of the brown coal. To develop a draught which causes the solid product particles to move along the return conduit, the latter is provided with a means for feeding a gaseous heat carrier.

Abstract: An arrangement comprises a pipeline filled with liquid at atmospheric pressure. The pipeline serves for displacement of containers with cargo therein by means of driven conveyors arranged along the pipeline. Endless traction members of the conveyors comprise belts having at least one row of equally spaced elements. Each container has at least one longitudinal groove with stops for engagement with the belt elements during the displacement of the containers. The arrangement according to the invention enables transportation of cargoes with comparatively low power consumption.
