加熱爐的分類:

按爐型結構分類：有箱式爐、立式爐等。  按燃燒形式分類：底燒式爐、側燒式爐。  按供風形式分類：強制供風爐、自然供風 .

Classification of heating furnace:

According to the type of furnace type structure, there are box type furnace, vertical furnace and so on. According to the form of combustion, the bottom burning furnace and the side burning furnace. Classification according to the form of air supply: forced air supply furnace and natural supply wind.

石油化學工業(yè)爐燃料氣與空氣混合物離開火孔速度一般都比較高，都超過其火焰?zhèn)鞑ニ俣?。但是燃燒器在結構上都有相應的措施保證不發(fā)生脫火現象，使火焰穩(wěn)定燃燒。

The mixture of fuel gas and air in the petrochemical furnace is generally higher than that of the flame, which is more than the flame propagation speed. But the structure of the burner has the corresponding measures to ensure that the flame is not degenerated and the flame can be burned steadily.

蓄熱式加熱爐是通過爐內熱交換過程進行的，蓄熱式加熱爐的爐內熱交換過程有三種基本方式，即：對流傳熱、傳導傳熱、輻射傳熱。

The regenerative reheating furnace is carried out through the process of heat exchange in the furnace. There are three basic ways in the heat exchange process of the regenerative heating furnace, namely, convection heat transfer, conduction and heat transfer, and radiation heat transfer.

蓄熱式加熱爐的輻射傳熱：輻射傳熱是物體熱射線的傳播過程，溫度越高，輻射能量越大，此種傳熱存在于爐氣對爐壁、爐氣和爐壁對鋼坯表面。

Radiation heat transfer of regenerative reheating furnace: radiation heat transfer is the propagation process of heat radiation of the object, the higher the temperature, the greater the radiation energy, the heat transfer exists in the furnace wall, furnace gas and furnace wall to the surface of the steel billet.
