采用辐射换热器来利用锻造炉烟气热量,是一个发展方向。因为辐射换热器比较便宜, 具有低的维护成本,高的热稳定性,便于装在炉子结构上和烟道里,即使在予热空气到200～400℃的情况下,也并不比对流换热器[1,2]的热效率差。西伯利亚冶金学院,在研制和推广适用于热功率达到3×10~6千卡/时的高温炉的单面和双面加热的可靠和有效的辐射换热器方面,积累了大量的经验。
Radiant heat exchanger to use forging furnace flue gas heat is a development direction. Because radiant heat exchangers are relatively inexpensive, have low maintenance costs, and have high thermal stability, they are conveniently installed in furnace structures and flue gasses, and are no less effective than convective heat transfer even when preheating air to 200-400 ° C The thermal efficiency of the device [1,2] is poor. The Siberian Institute of Metallurgy has accumulated a wealth of experience in the development and promotion of reliable and efficient radiant heat exchangers for single- and double-sided heating of high temperature furnaces with thermal power rates of 3x10-6 kcal / h.
