唐钢2×150t转炉煤气回收系统设计及运行实践

DESIGN OF GAS RECOVERY SYSTEM FOR 2×150T CONVERTER OF TANGSHAN IRON AND STEEL COMPANY AND RUNNING PRACTICE

在此较详细地介绍了唐钢一炼钢厂 2× 15 0t转炉煤气回收湿法除尘工艺和系统的技术特点。该系统设计吸收了国内外大型转炉煤气回收的经验。经近 18个月的生产实践 ;认为效果良好 ,煤气回收率近 80 % ,热值近 80 0 0kJ Nm3,放散排放浓度小于 80mg

The technical characteristics of the gas recovery system and wet dedusting process for No.1 steelmaking plant under Tangshan Iron and Steel Company were described in more detail.The experience in gas recovery of large sized converters both at home and abroad was used for the design of this system.Good results were obtained during the production period of June,1999 to the end of 2000.The gas recovery was about 80%;the caloricity was near to 8,000kJ/Nm 3 and the emission concentration of the dust was less than 80mg/m 3.
