马鞍山钢铁设计研究院研究开发的“加热炉余热利用和减少炉底管”研究成果通过部级鉴定。专家们认为,该项成果已达到主题预期目标,技术上先进,节能效果显著,居国内领先地位。对进一步提高加热炉热工水平、降低能源消耗,具有普遍的指导意义和推广价值。 该项成果在上海等地十几个厂家的20多台加热炉上应用效果表明:加热炉排烟温度降至200～300℃,余热回收率提高到50℃以上,水冷管热损失减至5～7％,加热炉热效率可达60～70％,节能率15～20％,经济效益显著。
Maanshan Iron and Steel Research Institute of research and development of “furnace waste heat utilization and reduce furnace bottom tube” research results through ministerial identification. Experts believe that this achievement has reached the theme of the desired goal, technologically advanced, significant energy-saving effect, ranking the leading domestic position. To further improve the thermal furnace level, reduce energy consumption, with a general guiding significance and promotion of value. The results in Shanghai and other places more than a dozen manufacturers of more than 20 heating furnace application shows that: furnace exhaust temperature dropped to 200 ~ 300 ℃, waste heat recovery rate increased to 50 ℃ above, water cooling pipe heat loss reduced to 5 ~ 7%, heating furnace thermal efficiency up to 60 ~ 70%, energy saving rate of 15 ~ 20%, significant economic benefits.
