Baosteel Baotou Steel output to the success of flue gas desulfurization
From;    Author:
Baosteel Baosteel developed by the Institute of red spout gas sintering flue gas desulphurization technology successfully complete clad steel output, and will soon start the construction. This is the second roller slag processing technology, Baosteel has a mature environmental technologies independently developed applications for the domestic counterparts. Iron and steel enterprises mainly from emissions of sulfur dioxide sintering flue gas, iron and steel enterprises emissions account for about 60% of total emissions. Earlier, the domestic steel companies sintering flue gas desulphurization plant desulfurization technology used, but not suited to sintering flue gas properties, the effect is not ideal. And foreign technology is not only complex process, and the investment and operating costs high. In 2005, the state, "Steel Industry Technology Development Guide" will focus on research and development topics as flue gas desulphurization. Baosteel then set up a "Study of sintering flue gas desulphurization technology" key scientific research projects. Sintering Gas R & D team for the complex characteristics of selected limestone - gypsum-based technical route, and take the lead in the stainless steel division in a pilot. After two years a series of studies under different operating conditions, the formation of sintering flue gas desulfurization, gas spout red absorber, flue gas cooling devices, complete sets of pre-core technology. In 2007, Baoshan Iron and Steel sintering flue gas desulfurization technology industry, has in the May 3, the sintering of steel, Baosteel Ironworks 3, sintering, sintered stainless steel, Division 1, the successful application. So far three projects put into operation, the technical and economic indicators have reached the expected goals in the industry played an exemplary role. Currently, the technology has developed 31 patents, of which 15 patents, technical secrets 35, forming a complete red Baosteel gas spout complete sintering flue gas desulphurization engineering technology. Baotou multiple sintering machine dry desulfurization technology early adopters, but the long application ineffective. To further improve the environment, meet the national environmental requirements, Baotou determined implementation of the transformation of sintered desulfurization. In visits to domestic steel companies, through comprehensive technical comparison, the final decision Bao Steel sintering flue gas desulphurization technology research and development.
