Abstract

Изобретение относится к способу нагрева газов в канале для циркуляции газа при непрерывном процессе спекания и устройству для его осуществления. В печи для спекания горячий газ подается сверху на ленту для спекания расположенного на ленте материала, и часть канала для циркуляции газа сформирована как зона горения или кольцо горелок, где газ нагревается. Кольцо горелок содержит, по меньшей мере, один блок горелок, направленных внутрь от окружности канала для циркуляции газа.Международная заявка была опубликована вместе с отчетом о международном поиске.
