FIELD: personal use articles.SUBSTANCE: invention relates to a dryer (1) with pseudoliquid layer with indirect heating for drying wet fine-grained bulk materials, such as brown coal, comprising a housing (2) with gaseous bottom (6), with the built-in heat exchanger elements passing over the gaseous bottom (6), and with provided under the gaseous bottom (6) at least one discharge device for dried bulk material. And the useful clear opening of the housing flow in the area of the built-in heat exchanger elements increases along the entire height of the built-in heat exchanger elements in the direction of the flow of the fluidising gas. According to the invention, the cross-section of the housing (2) is constant, and the density of mounting of the built-in heat exchanger elements in the direction of flow of fluidising gas decreases.EFFECT: prevention of impermissible extension of stationary pseudoliquid layer.17 cl, 2 dwg |
