Abstract

Способ защиты внутренней стенки (12) шахтной печи, причем способ включает в себя шаги: обеспечение по меньшей мере одного устройства (28) вдувания через внутреннюю стенку (12), причем устройство (28) вдувания выполнено для вдувания защитного материала в шахтную печь, и вдувание по мере необходимости защитного материала в шахтную печь по меньшей мере через одно устройство (28) вдувания таким образом, что защитный материал наслаивается с образованием защитной стенки между внутренним пространством шахтной печи и стенкой (12) печи.
