Application of Double-regenerative Radiant Tube Technology on Roller Hearth Normalizing Furnace
Energy Procedia(2015)
摘要
With the improvement of energy utilization rate, there is a growing attention on the utilization of gas having low calorific value, therefore, the double-regenerative radiant tube combustion technology comes into being accordingly. This paper presents the necessity of double-regenerative radiant tube combustion technology applied in roller-hearth type normalizing furnace, based on the characteristics of heat treatment process as well as the work principle of regenerative combustion. By building a combustion mathematical model, the numerical simulation on combustion process of double-regenerative radiant tube is made, and the distribution of temperature field and speed field of radiant tube is studied, it provides a basis for the application of double-regenerative radiant tube combustion technology.
