              以上是對加熱爐的總的基本要求,在加熱爐用于油氣田具體環節時,需要注意工作介質和工作環境,以及提高生產率、提高加熱質量和降低燃料消耗量等各項指標之間的關系,這些因素通常是統一的,但有時則有主有次。



              The above is the basic requirement of the total heating furnace, for oil and gas fields in the following aspects: heating furnace, the need to pay attention to the working medium and working environment, and improve the productivity, improve heating quality and reduce fuel cumption relatihip between each index weight, these factors are usually unified, but sometimes there are times the lord.


              加熱爐的分類:

              1.有純加熱爐,如常壓爐、減壓爐等;有加熱爐反應爐,如裂解爐、焦化爐等。  

              2.按傳熱方式分類:有純對流式爐、輻射對流式爐和輻射式爐。

              The classification of the heating furnace:

              1. there are pure heating furnaces, such as ctant pressure furnace, pressure reducing furnace, and so on; there are reheating furnace reaction furnaces, such as cracking furnace and coking furnace.  

              2. classified according to the heat transfer mode: there are pure convection furnace, radiant convective furnace and radiant furnace.




              空氣過剩系數:增大空氣過剩系數,可以加速混合,使火焰變短,反之則混合緩慢,火焰拉長。這兩種情況都有一些實際利用的例子。


              Air surplus coefficient: increase the air surplus coefficient, can accelerate the mixing, make the flame shorter, and vice versa, slow mixing, flame elongated. There are some examples of practical use of these two cases.


              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.
