Abstract
В заявке описан способ эксплуатации шахтной печи, в котором в верхнюю часть шахтной печи загружают сырье, которое под действием силы тяжести спускается внутрь шахтной печи, и под действием атмосферы, преобладающую в шахтной печи, часть сырья плавится и/или восстанавливается, а в нижнюю часть шахтной печи нагнетают технологический газ, чтобы, по меньшей мере, частично изменить атмосферу, преобладающая в шахтной печи. Давление и/или объемный расход нагнетаемого технологического газа динамически модулируют в течение временного интервала, равного 40 с. Также описана шахтная печь, эксплуатируемая упомянутым способом, за счет чего обеспечивают улучшенное сквозное выдувание газа.
