摘要： To provide a method for operating a blast furnace with which the combustion efficiency of a solid fuel, such as pulverized coal, is improved, thereby making it possible to improve productivity and reduce CO2 emissions. Pulverized coal and LNG are blown from an upstream lance configured by a double tube, and oxygen is blown from a downstream lance on the downstream side in a hot air blast direction, so that oxygen used for preceding combustion of the LNG is supplied from the downstream lance, and the pulverized coal whose temperature has been increased by the combustion of the LNG is combusted along with the supplied oxygen. When a direction perpendicular to the hot air blast direction is designated as 0° , and a downstream direction and an upstream direction therefrom in the hot air blast direction are designated as positive and negative, respectively, a blowing direction of the oxygen from the downstream lance with respect to the blast direction ranges from −30° to +45° , and a blowing position of the oxygen from the downstream lance with reference to a position at which the upstream lance is inserted into a blast pipe ranges from 160° to 200° in terms of a blast pipe circumferential direction angle.

摘要： A ceramic burner for gas, for a combustion chamber of a hot-blast stove of a blast furnace, has parallel vertical supply ducts for the two combustion components (gas and air). A first one of said ducts opens upwardly at a first outlet which is substantially oblong in plan view and the second of said ducts opens at a plurality of second outlets which are located on either side of and above the first outlet, the general discharge directions of the second outlets being oblique to that of the first outlet. In order to provide improvement in the mixing and homogenisation of the combustion components, the first outlet has, as seen in plan view, a slot shape and has, in its long sides, a plurality of recesses which extend outwardly towards the second outlets. The second outlets are arranged alongside the said long sides of the first outlet with the second outlets on one side opposite those on the other side. The recesses are, along the length of the first outlet, located alternately in said long sides and, on each said long side, directed towards alternate ones of said second outlets.
