Innovative technologies of processing the technological group 1B brown coals from Upper and Middle Pryamurye

Energy-saving technology of natural drying, separation into size grades by grating, elimination briquet-ting in rotary presses is offered by the results of research of low-calorific brown coals of technological group 1Б. Natural drying saves to 250kg of coal on each ton of dried lignite, calorie content raises on 4-5 MJoule/kg. It is offered to process the dried lignite by HSP method on plants with the firm heat-carrier with reception of coal char, liquid products and commodity gas. One mixes the coal char with dried lig-nite, thermostates and then briquettes that excludes necessity of recycling of ash-and-slad dumps near FHCP.
