摘要
对蓄热式燃烧技术的原理进行了简要概述,通过对周期性加热炉的非稳态传热特性进行分析,阐明了蓄热式燃烧在升温段燃料消耗量最大时,具有极高的节能特性。介绍了蓄热式燃烧技术在兵器工业集团锻造加热炉中的成功实例,与改造前对比,排烟温度由600℃降至137℃,实现了烟气余热的极限回收;炉子平均单耗由423.02m3.t-1下降至123.18m3.t-1,吨钢运行成本由1650元下降至480元,年节约天然气费用81.86万元,节能效益显著。
The principle of regenerative combustion technology was briefly described,through the analysis of unsteady heat transfer characteristics on the periodic heating furnace,the high energy-saving features was expounded when the fuel consumption of regenerative combustion was the biggest in heating period.The successful example of regenerative combustion technology in ordnance industry group forging heating furnace was introduced.Compared with the transformation of the former,the exhaust gas temperature decreases from 600 ℃ to 137 ℃,and the ultimate recovery of flue gas waste heat is realized.The average unit consumption decreases from 423.02 m3·t-1 to 123.18 m3·t-1,operating costs per ton of steel drops from 1650 yuan to 480 yuan,and the gas saving achieves 818600 yuan per year,which show that the energy-saving benefit is remarkable.
