Представлены результаты расчетов технологических параметров процесса металлизации формованных рудно-угольных материалов в кольцевой печи с вращающимся подом, отапливаемой генераторным газом. Усовершенствована система утилизации тепла отходящих из кольцевой печи дымовых газов путем введения дополнительных контуров после паровой турбины, позволяющих вырабатывать тепловую и электрическую энергию. Изменена схема подвода теплоносителя к рекуператорам для подогрева воздуха и генераторного газа и к решетке для подогрева окатышей или брикетов с целью обеспечения их более высоких температур. Рассчитан ориентировочный экономический эффект от технических преобразований энерготехнологической установки металлизации рудно-угольных материалов.

The article describes the calculation results of technological parametersof 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.
