摘要： PROBLEM TO BE SOLVED: To highly accurately determine blowing abnormality of combustion-supporting gas without using furnace pressure.SOLUTION: Pulverized coal together with combustion-supporting gas is blown into a blast furnace 1 from a tuyere 3 via a blast tube 2 using the blast tube 2 connected to the tuyere 3 of the blast furnace 1 and a double-tube lance 4. When a blast pressure to the blast tube 2 is denoted as Pb, a pressure to a combustion-supporting gas flow path 4B is denoted as Px, a flow velocity to the blast tube 2 is denoted as Vb, a flow velocity to the combustion-supporting gas flow path 4B is denoted as Vx, and a deviation between a pressure loss difference (ΔPb-ΔPx), which is a difference between a pressure loss ΔPb in the blast tube 2 obtained from the flow velocity Vb and a pressure loss ΔPx in the combustion-supporting gas flow path 4B obtained from the flow velocity Vx, and a pressure difference (Pb-Px), which is a difference between the blast pressure Pb and the combustion-supporting gas pressure Px, is greater than a predetermined allowable pressure ΔV, it is determined that blowing abnormality of the combustion-supporting gas occurs.

摘要： PROBLEM TO BE SOLVED: To provide a blast furnace operation method, in the case dust coals with different descriptions are blown from different lances, capable of efficiently increasing the burning rate of the whole of the dust coals to be blown.SOLUTION: The descriptions and blowing quantity of the dust coals blown from lances 4 are decided in advance, and the increasing slant of the dust coal burning rate to the increasing quantity of the blowing quantity of the oxygen to be blown is obtained in advance. In the case the increasing slant of the dust coal burning rate to the increasing quality of the oxygen to be blown has been known per description and blowing quantity of the dust coal, the burning rate of the whole of the dust coals in accordance with the oxygen blowing quantity from each lance 4 can be found from the weighted average burning rate of the dust coal blowing quantity. At this time, when the blowing quantity of the oxygen blown from each lance 4 is increased in the high order of the increasing slant of the burning rate of the dust coal blown from all the lances 4, the burning rate of the whole of the dust coals is most efficiently increased. For obtaining the maximum efficiency burning rate, the blowing quantity of the oxygen blown from each lance 4 is set in accordance with the description and blowing quantity of the dust coals blown from all the lances 4.
摘要翻译：要解决的问题：为了提供高炉操作方法，在具有不同描述的粉煤从不同的喷枪吹出的情况下，能够有效地提高整个被吹入的粉煤的燃烧速度。解决方案：预先确定从喷枪4喷出的粉尘煤的吹出量，并预先获得粉煤燃烧速度的上升倾向与吹送氧量的增加量的增加。在这种情况下，粉尘煤燃烧速率的上升倾向与待吹氧气质量的提高是已知的，并且粉尘煤的吹入量，根据氧气的整体粉煤的燃烧速率可以从粉煤喷吹量的加权平均燃烧速率中找出每个喷枪4的吹送量。此时，从喷枪4喷出的粉尘煤的燃烧速度的倾斜倾斜的高位，从每个喷枪4吹出的氧气的吹送量增加时，整个灰尘的燃烧速度煤炭效率最高。为了获得最大效率燃烧率，根据从所有喷枪4吹送的粉尘煤的描述和吹送量来设定从每个喷枪4吹出的氧气的吹送量。
