Abstract
1. Способ подачи газообразных углеродсодержащих реагентов в доменную печь, включающий предварительный нагрев реагентов, подвод предварительно нагретых реагентов в дутьевую фурму и их ввод в рабочем канале фурмы в поток горячего дутья с последующей подачей в фурменную зону горна доменной печи, отличающийся тем, что подвод предварительно нагретых реагентов в дутьевую фурму осуществляют по теплоизолированному газопроводу, а их ввод в поток горячего дутья в рабочем канале фурмы осуществляют на расстоянии от среза фурмы, которое составляет 1,0-1,5 диаметра рабочего канала фурмы, так, чтобы ось потока предварительно нагретых реагентов не пересекалась со стенкой рабочего канала фурмы.2. Способ по п.1, отличающийся тем, что предварительный нагрев реагентов осуществляют путем их пропускания через внутренний контур охлаждения плитовых холодильников системы охлаждения доменной печи, при этом предварительный нагрев осуществляют за счет утилизации теплоты, создаваемой тепловым потоком от рабочего пространства доменной печи и воспринимаемой телом плитовых холодильников.3. Способ по п.1, отличающийся тем, что предварительный нагрев реагентов осуществляют путем их пропускания по газопроводу, установленному вдоль внутреннего пространства дымового борова воздухонагревателей доменной печи, при этом предварительный нагрев осуществляют за счет утилизации теплоты, создаваемой тепловым потоком от дымовых газов воздухонагревателей. 1. A method of supplying gaseous carbon-containing reagents to a blast furnace, which includes preheating the reagents, supplying preheated reagents to the blowing lance and introducing them into the hot blast channel in the lance working channel, followed by feeding the blast furnace hearth to the tuyere, characterized in that heated reagents in the blowing lance are carried out through a thermally insulated gas pipeline, and their input into the hot blast stream in the working channel of the lance is carried out at a distance from the lance cut, which is 1.0-1.5 of the diameter of the working channel of the lance, so that the axis of the flow of preheated reagents does not intersect with the wall of the working channel of the lance. 2. The method according to claim 1, characterized in that the preheating of the reactants is carried out by passing them through the internal cooling circuit of the stove coolers of the blast furnace cooling system, while the preheating is carried out by utilizing the heat generated by the heat flux from the working space of the blast furnace and perceived by the stove body refrigerators. 3. The method according to claim 1, characterized in that the preheating of the reactants is carried out by passing them through a gas pipeline installed along the inner space of the flue gas of the blast furnace air heaters, while the preliminary heating is carried out by utilizing the heat generated by the heat flow from the flue gases of the air heaters.
