摘　　要：叙述了利用高效蓄热燃烧技术开发的高效蓄热式工业炉 ,将蓄热式热回收和换向式燃烧系统与炉体结合于一体 ,可将空气和煤气双预热到 110 0℃ ,系统排烟温度低于 130℃ ,可在轧钢加热炉上以全高炉煤气为燃料。工业炉热效率达到 70 %以上 ,并提高加热质量、减少钢坯氧化烧损。在工业炉上应用的实际结果表明The technical characteristics and commercial application of North Island highly efficient regenerative industrial furnaces are introduced. The high efficiency regenerative industrial furnace (NIF) combines the high efficiency regenerative heat recovery system with the furnace. The gas and air are pre heated over 1100 ℃.The off gas temperature is less than 150 ℃. The reheating furnace in rolling mill can be worked only on blast furnace gas. The heat efficiency is higher than 70 %. The results show that the NIF is greatly benefit to energy saving, consumption reduction and environment protection.
