摘要： A method for operating a blast furnace that makes it possible to further increase combustion temperature and reduce a unit consumption of reducing agent is provided. When two or more lances for injecting reducing agents from a tuyere are used, and LNG is used as a flammable reducing agent and pulverized coal is used as a solid reducing agent, a position of an end of the lance for injecting LNG is situated closer to a near side in a injecting direction by more than 0 to 50 mm than a position of an end of the lance for injecting pulverized coal. By this, the LNG effectively raises the temperature of the pulverized coal. The LNG contacts oxygen and undergoes combustion earlier, so that explosive diffusion occurs and the temperature of the pulverized coal is drastically increased. This makes it possible to drastically increase the combustion temperature and, thus, to reduce the unit consumption of reducing agent. In addition, when a double wall lance is used as a lance for injecting pulverized coal, the pulverized coal is injected from the inner tube and oxygen is injected from the outer tube, so that it is possible to provide oxygen necessary to the combustion of the pulverized coal and to further increase combustibility. The outlet flow velocity at the lance is 20 to 120 m/sec to prevent deformation of the lance.
摘要翻译：提供一种操作高炉的方法，其使得可以进一步提高燃烧温度并减少还原剂的单位消耗。当使用用于从风口喷射还原剂的两个或更多个喷枪，并且使用LNG作为可燃性还原剂，并且将粉煤用作固体还原剂时，用于喷射LNG的喷枪的端部的位置位于更接近在喷射方向上的近侧比用于注入粉煤的喷枪的端部的位置大大超过0至50mm。由此，LNG有效地提高了粉煤的温度。液化天然气与氧气接触并较早地进行燃烧，从而爆炸扩散，粉煤的温度急剧上升。这使得可以显着增加燃烧温度，从而降低还原剂的单位消耗。此外，当使用双壁喷枪作为喷射煤粉的喷枪时，从内管注入粉煤，并从外管注入氧气，从而可以提供燃烧所需的氧气粉煤并进一步增加可燃性。喷枪出口流速为20〜120m / sec，防止喷枪变形。
