| 摘 要： | 对比分析了石灰石造渣炼钢工艺相较于现行石灰造渣炼钢工艺的节能减排环节，采用IPCC提供的排放因子法计算了每个环节的节能减排量，结果表明，石灰石造渣炼钢工艺较现行工艺节省能耗18.32kg(标煤)/t(钢)，相当于减排45.80kgCO2/t(钢)；减排粉尘量约5.34g/t(钢)，SO2约14.15g/t(钢)、NOx约70.77g/t(钢)，减排可致灰霾颗粒物127.39g/t(钢)。

| Abstract: | The links of energy conservation and emissions reduction in the new steelmaking process by slagging with limestone were compared with that in the current lime- steelmaking process. The energy conservation effect of each link was calculated by the IPCC emission factor method. The result showed that energy consumption in new process decreased by 18.32kg/t(steel) in comparison with that in the current process, which was equivalent to 45.80kgCO2 /t(steel) emission reduction. At the same time, the new technology can reduce the emissions of the dust, SO2, NOX and ash haze particles by 5.34g/t(steel), 14.15g/t(steel), 70.77g/t(steel) and 127.39g/t(steel), respectively. |
