Intensive technologies for drying a lump material in a dense bed

详细

The article is devoted to the urgent scientific and practical problem of energy and resource conservation upon drying a lump material in a dense bed. A mathematical model of heat and mass transfer in a dense bed and the verification of its adequacy have been presented. The problem of optimizing energy consumption based on the intensification of the in-bed drying process has been solved by generating a decaying thermal wave. The operation mode has been considered for a conveyor type roasting machine under obtained optimal parameters. The potentialities of resource and energy conservation have been revealed in the technology for the thermal treatment of lump materials in a dense bed using conveyor type roasting machines.
