一、现代化氧气转炉炼钢厂的烟气净化工业纯氧的应用使炼钢生产发生了革命,并导致在世界范围内兴建现代化的氧气炼钢厂。在氧气炼钢厂中,采用氧使生铁炼成钢的工艺时,通常将产生高含尘量的烟气。这种钢厂的烟气即所谓污染的褐色烟尘,含有大量的细小氧化铁颗粒,它是由蒸发的铁粒通过升华作用被氧化成FeO和Fe_2O_3而形成的。吹炼时产生的转炉烟气伴随有 I. Flue Gas Purification of Modern Oxygen Converter Steel Mills The application of pure oxygen to the industry revolutionized steelmaking and led to the construction of modern oxygen steel mills around the world. In oxygen steel mills, the practice of using oxygen to make pig iron into steel often results in a high dust content of the flue gas. The flue gas from this mill, the so-called contaminated brown fume, contains large amounts of fine iron oxide particles formed by the evaporation of iron particles by sublimation into FeO and Fe 2 O 3. Converter flue gas generated when blowing is accompanied by
