Abstract
The article describes the calculation results of technological parameters
of metallization process of molded ore-coal materials in circular furnace with rotary bottom heated by generator gas. The circular furnace waste gases heat utilization system can be improved by means of additional contours after steam turbine, allowing to produce heat and electrical energy. The scheme of heat carrier transportation to recuperates for air and generator gas heating and to grating for spherules or briquettes heating was changed to achieve higher temperatures. The potential economic effect from the technical transformations of energy technological installation was calculated for metallization of ore-coal materials.
