泰钢45t转炉煤气回收系统的结构特点及应用实践

Structural Feature and Application Practice of 45t Converter Gas Recovery System at Taigang

泰钢45t转炉煤气回收系统应用"OG"法回收煤气。该系统采用了R-D文氏管、炉口微差压仪表自动调节装置、气体分析装置、干式煤气柜等多项先进技术和设备。应用表明,吨钢回收煤气70m3,煤气热值近6000kJ/m3,年减少大气粉尘排放7 2t,为"负能炼钢"奠定了基础。

The means of 'OG' is adopted at Taigang 45t converter gas recovery system. The system adopts lots of advanced technologies and devices such as R-D Venturi tube, micro-differential meter accurately and automatically adjusting device for converter mouth, gas analyzing device and dry-style gas cabinet etc. The practices show that the gas recovery of one-ton steel is 70m\+3, the gas burning value is 6000kJ/m\+3 and the dust emission is reduced by 7.2t every year. It establishes the base for steel-making with negative energy.
