【摘要】 济钢炼铁厂于2005年2月和5月建造的2#、3#1750m³高炉热风炉上使用了山东慧敏科技开发有限公司自主研发的高效蓄热体技术。投产后,对比了3#高炉使用高效蓄热体技术的3座热风炉与1#高炉（2003年投产）未使用该技术的3座热风炉的热风温度,对比了2#高炉无此技术的1#热风炉与使用该技术的2#热风炉的过渡区格子砖温度。对比结果表明:使用1年后,3#高炉热风炉比1#高炉热风炉风温平均提高22.5℃;使用4年后,3#高炉热风炉比1#高炉热风炉风温平均提高19.2℃。2#高炉2#热风炉过渡区格子砖比1#热风炉格子砖燃烧期平均温度4年后提高74.36℃,送风期平均温度提高37.85℃。按照3#高炉热风炉4年平均提高风温计算,3#高炉年平均节焦增铁效益2071.6万元,年节省焦炭7938吨,年CO₂排放量减少1.9万吨。更多还原

【Abstract】 High efficiency regenerator technology（HERT） self—developed by SDHM Co.,Ltd. was applied on JiGang 2# and 3# 1750m³ BF hot stove constructed in February and May 2005. When these two BF put into production,we compared the hot blast temperature of 3# BF three hot stoves using HERT with 1# BF hot stoves withnot HERT,which start production in 2003, and then compared the brick temperature difference in transition zone between 1# hot stove unusing HERT and 2# hot stove with HERT both in 2# BF system. The results show that the hot blast average temperature of 3# BF hot stoves using HERT was 22.5℃higher than 1# BF hot stoves 1 years later,and was 19.2℃higher than 1# BF hot stoves after using 4 years later.At that time,the checker bricks temperature in transition zone of 2# hot stove increased 74.36℃than 1# hot stove of 2# BF system on gas of stove,and improved 37.85℃on gas of stove.According to the blast average temperature in 4 years of 3# BF,the benefit of coke—saving and iron—increasing is up to 20.716 million yuan per year,and 7.938 thousand tons coke is saved,and 1.9 million tons CO₂ is reduced.更多还原
