Шахтная печь для обжига кускового минерального материала работает по прямоточно-регенеративному методу и имеет две шахты, которые на переходе от зоны обжига к зоне охлаждения имеют образующее внутренний буртик расширение, где происходит перетекание отходящих газов в смежную шахту. Этот расширенный участок цилиндрической формы проходит до донного отверстия шахт, перекрываемого разгрузочным устройством. Такая форма шахтного пространства наряду с улучшением распределения топлива и усовершенствованием загрузочного устройства обеспечивает обжиг известняка с величиной зерен от 10 до 30 мм при удовлетворительном качестве продукции, что до сих пор невозможно было делать в шахтных печах.The shaft kiln for burning of lumpy mineral material works by a direct-flow-regenerative method and has two mines, which, at the transition from the burning zone to the cooling zone, have an extension forming an internal bead, where the overflow of exhaust gases into the adjacent shaft occurs. This expanded portion of the cylindrical shape extends to the bottom hole of the shafts, covered by a discharge device. This form of mine space, along with improved fuel distribution and improvement of the loading device, ensures limestone burning with grain size from 10 to 30 mm with satisfactory product quality, which was still impossible to do in shaft furnaces.
