鞍钢高炉共有热风炉34座,每小时烟气排放总量约140×10~4m~3n,烟气温度一般在250～350℃。为了回收利用这部分余热资源,1987年12月在鞍钢5号高炉大修时,我们设计了低温余热锅炉,投产至今已安全运行4年。实践表明,该余热锅炉回收烟气余热效果好,达到了设计指标,生产的蒸汽解决了鞍钢炼铁厂的生产和生活用汽。
Anshan Iron and Steel Blast Furnace has a total of 34 stoves, the total hourly flue gas emissions of about 140 × 10 ~ 4m ~ 3n, flue gas temperature is generally 250 ~ 350 ℃. In order to recycle this part of waste heat resources, we designed a low-temperature waste heat boiler at the time of the overhaul of No.5 BF at Anshan Iron & Steel Co., Ltd. in December 1987 and has been operating safely for 4 years. Practice shows that the residual heat recovery flue gas waste heat recovery effect is good, to meet the design specifications, the production of steam to solve the Angang Ironworks production and domestic steam.
