摘要
在烧结厂的设计和生产中,环保问题已经成为了决定性的因素。如今,在许多城市地区,新建烧结厂或现有烧结厂扩建,只有在确保严格执行环保排放规定的情况下才能得到批准。采用传统技术往往不可能达到现行排放标准,更不必说排放标准预计会在中短期内变得进一步严格。有鉴于此,作为一家领先的冶金工业设备制造商,西门子奥钢联开发并实施了新技术,能够将烧结生产的环境排放指标降低到前所未有的水平。通过采用与奥钢联钢铁公司联合开发的称之为Eposint的烧结废气选择性循环系统,加上西门子奥钢联开发的MEROS新型废气干法除尘系统,这一目标得以实现。目前,这两种工艺均已在奥钢联钢铁公司第5烧结厂投入运行,环保效果远远好于预期指标。
Environmental aspects are already decisive criteria in the design and operation of sinter plants. It is now mandatory in many urban areas and municipalities that permission for the installation of new sinter plants or for the expansion of existing facilities will only be granted when strict environmental emission values are guaranteed. With conventional technologies it is often not possible to meet currently imposed emission limits - without even considering the continually increasing demands expected in the short- to mid-term future. Siemens VAI, a leading plant builder for the metallurgical industry, has therefore developed and implemented new technologies which enable environmental emissions in sinter production to be reduced to previously unattained levels. This has been achieved with the introduction of a selective sinter-waste-gas recirculation system, referred to as Eposint-jointly developed with the Austrian steel producer voestalpine Stahl-in addition to a new dry-type gas-cleaning system known as MEROS , devel- oped by Siemens VAI. Both of these processes are now in operation at the Sinter Plant No. 5 of voestalpine Stahl and the environmental benefits have exceeded expectations by far.
