Abstract

Способ подачи природного газа в доменную печь, включающий его подогрев до ввода в воздушную фурму путем использования природного газа в качестве охлаждающей среды для охлаждения элементов фурменных приборов, отличающийся тем, что в конструкции фурменного прибора между фурмой и коллектором предусмотрен обводной соединительный патрубок, через который, в зависимости от теплового режима доменной печи, производят подачу природного газа при давлении 3-12 кг/см2 с расходом до 1000 м3/ч, причем в момент раздувки и остановки доменной печи, а также при разгерметизации элементов фурменного прибора, их охлаждение производят азотом при давлении 3-12 кг/см2 с расходом 50-800 м3/ч.A method of supplying natural gas to a blast furnace, including heating it before entering the air lance by using natural gas as a cooling medium for cooling the elements of the tuyere devices, characterized in that in the design of the tuyere device between the tuyere and the collector a bypass connecting pipe is provided through which depending on the thermal regime of the blast furnace, natural gas is supplied at a pressure of 3-12 kg / cm2 with a flow rate of up to 1000 m3 / h, and at the time of blowing and stopping the blast furnace, as well as depressurization elements tuyere assembly, their cooling produce nitrogen at a pressure of 3-12 kg / cm2 at a rate of 50-800 m3 / h.
