Latest developments in sinter technology especially concerning relevant environmental issues are presented in this paper. The Siemens VAI selective waste gas recirculation system can be installed in existing or in greenfield plants, as 100 % add-on or fully integrated. As another highlight of this off-gas recirculation system, in combination with the Meros (Maximized Emission Reduction of Sintering) process it represents one of the best available techniques for a cleaner sintering process.

The objective of this paper is to present the latest developments of Siemens VAI Sinter Technologies especially concerning the cost savings potential that can be achieved in existing sinter plants and eventually in the Blast Furnace. The Siemens VAI Sinter Technologies consists of innovative solutions and design packages which enhance sinter quality and productivity thus generating ideal blast furnace burden for optimized production. An advantage of using sinter is that the blast furnace burden can be optimized by adjusting the quality and the ratio of the charged sinter in accordance with the composition and characteristics, while pellets and lump ore are normally marketed with specific chemical compositions and qualities.

The latest developments of Siemens VAI sinter technology, an offgas recirculation system that reduces pollutants of the sintering process, is discussed. In the Siemens VAT Selective Waste Gas Recirculation System, the gas flow for recirculation purposes is taken only from specifically selected wind boxes in the area of interest, at the zone located approximately in the third quarter of the wind boxes along the sintering strand. The concentration of sulfur dioxide (SO 2) is highest in the area of the temperature rise along the sintering strand. The carbon monoxide (CO) content in the waste gas recycled to the sinter strand is combusted in the flame front. The most important benefits of the Siemens VA! Selective Waste Gas Recirculation System when installed at an existing sinter plant are increase of production capacity by 30% and up to 40% lower specific offgas volume. Source
