摘要： A method and apparatus for recovering blast furnace gas for utilizing in a power plant such as an electric power generator employs a plurality of cooling arrangements. The cooling arrangments includes a first arrangement located upstream of a dust-removal equipment for controlling temperature of blast furnace gas to be about or below a critical temperature of the dust-removal equipment. The cooling arrangments also include a second arrangement located downstream of the dust-removal equipment and upstream of a power generator turbine for controlling gas temperature to be about or below a critical temperature of the turbine. The first and second arrangements are operative independently of each other in response to gas temperature.

摘要： An air blast type slag cut-off device for steel converter, adapted for jetting compressed air or gas from a nozzle toward the tap hole of the steel converter to force the slag coming out of the tap hole back into the steel converter. The device has a shut-off valve disposed at a portion of the high-pressure gas pipe just upstream from and in the close proximity of the nozzle. The high-pressure gas pipe and an operating fluid supply pipe for operating the shut-off valve are connected to respective sources through a common rotary joint or through independent flexible hoses, so that the steel converter can be tilted smoothly while maintaining the fluid communication between the pipes and respective sources. The time lag of jetting of the air or gas from the nozzle is minimized thanks to the reduced length of the passage between the shut-off valve and the nozzle.

摘要翻译： 一种用于钢转炉的鼓风式炉渣切断装置，用于将压缩空气或气体从喷嘴向钢流转换器的排放孔喷射，以迫使熔渣从出钢孔中排出回钢转炉。 该装置具有一个截止阀，该截止阀设置在高压气体管道的一部分正好在喷嘴的上游和紧邻喷嘴附近。 用于操作截止阀的高压气体管道和工作流体供给管道通过公共旋转接头或通过独立的软管连接到相应的源，使得钢制转炉可以平稳地倾斜，同时保持流体连通 管道和各自的来源。 由于截止阀和喷嘴之间的通道的长度减小，使喷嘴中的空气或气体喷射的时间延迟最小化。
