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.

燃料氣的發熱值:當其他條件相同時，燃料氣的發熱量越大，燃燒需要的空氣量就越多，其混合時間也就越長。當爐子的燃料由熱值低的燃料改為高熱值燃料時，為了保證其完全燃燒，燃燒器在設計時需要注意改善燃料氣與空氣的混合條件。

The heating value of fuel gas when other conditi are the same, the greater the calorific value of fuel gas, the amount of air needed for burning more, the mixing time is longer. When the fuel of a furnace is changed from a fuel with low calorific value to a high calorific value fuel, in order to ensure its complete combustion, it is necessary to pay attention to improving the mixing condition of fuel gas and air in the design of the burner.

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.

對流傳熱：對流傳熱是爐氣與鋼材表面接觸時的熱交換過程，包括爐氣各部分發生位移所產生的對流作用及爐氣分子之間的導熱作用。

Convective heat transfer: convection heat transfer is the heat exchange process of the contact between the furnace gas and the steel surface, including the convection of the displacement of each part of the furnace gas and the heat conduction between the molecules of the furnace gas.
