Description

Известны экранированные дутьевые доменные фурмы с огнеупорным экраном, нанесенным на внутреннюю поверхность фурмы, с целью экономии тепла и дутьевого воздуха.Known shielded blast blast tuyeres with a refractory screen deposited on the inner surface of the tuyere to save heat and blast air.

Особенность изобретенной доменной дутьевой фурмы заключаетс  в том, что, с целью сохранени  тепла, вносимого дутьем и подогрева подаваемого в печь через фурму природного газа, она выполнена с кольцевым зазором и с жаростойким экраном, расположенным по внутренней стенке фурмы.The peculiarity of the invented blast furnace tuyere is that, in order to preserve the heat introduced by the blast and preheat the natural gas supplied to the furnace through the tuyere, it is made with an annular gap and a heat-resistant screen located along the inner wall of the tuyere.

На чертеже изображена экранизированна  фурма в продольном разрезе.The drawing shows a screened lance in a longitudinal section.

Описываема  фурма дл  подачи гор чего дуть  и природного газа сделана с применением пустотелого фланца /, с шаровидной заточкой дл  сопла. Во внутреннюю полость фланца подводитс  природный газ, который, равномерно распредел  сь по всей полости через отверстие 2, сделанное по внутреннему диаметру фланца, затем поступает в кольцевую камеру 3, расположенную между жароупорным экраном 4 и внутренней стенкой 5 фурмы. Природный газ, проход  по кольцевой камере фурмы, нагреваетс  и поступает в печь с увеличенной скоростью.The described lance for supplying hot blowing and natural gas is made using a hollow flange /, with a spherical sharpening for a nozzle. Natural gas is supplied to the internal cavity of the flange, which, evenly distributed throughout the cavity through an opening 2 made according to the internal diameter of the flange, then enters the annular chamber 3 located between the heat-resistant screen 4 and the internal wall 5 of the tuyere. Natural gas, the passage through the annular chamber of the tuyere, is heated and enters the furnace at an increased rate.

Предмет изобретени Subject invention

Экранированна  дутьева  фурма доменной печи, отличающа с  тем, что, с целью сохранени  тепла, вносимого дутьем, и подогрева природного газа, подаваемого в печь, фурма выполнена с кольцевым зазором между жаростойким экраном и внутренней стенкой фурмы, через который природный газ поступает в печь.The screened blast lance of the blast furnace, characterized in that, in order to preserve the heat introduced by the blast and preheat the natural gas supplied to the furnace, the lance is made with an annular gap between the heat-resistant screen and the inner wall of the lance through which natural gas enters the furnace.
