Abstract

Піч з обертовим подом містить засіб для завантаження агломерату на під цієї печі, засіб для вивантаження назовні з печі нагрітого в ній матеріалу і засіб для випускання відхідного газу в печі назовні з печі. Ця піч містить зону нагрівання і зону, яка не нагрівається. Засіб для випускання газу печі, який відходить назовні з печі, встановлений в зоні, яка не нагрівається. Засіб для впускання в піч зовнішнього повітря встановлений в зоні, яка не нагрівається, і на стороні вище за течією у напрямку потоку відхідного газу від засобу для випускання відхідного газу назовні з печі.
