Abstract

Способ вдувания угольной пыли в доменную печь включает подготовку фурменного рукава для вдувания горячего воздуха для дутья из кольцевого трубопровода в под доменной печи, подготовку форсунки для вдувания угольной пыли в фурму, обеспечение образования на конце форсунки смеси угольной пыли и горючего газа и сгорания смеси угольной пыли и горючего газа в фурме. Форсунка для вдувания угольной пыли содержит внутреннюю трубу для транспортировки угольной пыли и расположенную коаксиально вокруг внутренней трубы внешнюю трубу для транспортирования горючего газа. Внутренняя труба форсунки образовывает разделительную стенку для отделения угольной пыли от горючего газа. Способ также включает контроль присутс
