以上是对加热炉的总的基本要求，在加热炉用于油气田具体环节时，需要注意工作介质和工作环境，以及提高生产率、提高加热质量和降低燃料消耗量等各项指标之间的关系，这些因素通常是统一的，但有时则有主有次。

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.

燃料气的流动速度 燃料气的流动速度与火焰的长短有密切关系，在外混式燃烧器中，燃料气流速过大，会引起脱火；在半预混燃烧器中，燃料气流速过小会引起回火。

There is a close relatihip between the flow velocity and flow velocity of flame fuel gas fuel gas in the length of the outer mixing burner, fuel gas flow rate is too large, will cause the removal of fire; in the semi premixed burner, fuel gas flow rate is too ***all will cause tempering.

在冶金工业中，加热炉是将物料或工件（一般是金属）加热到轧制成锻造温度的设备（工业炉）。

加热炉应用遍及石油、化工、冶金、机械、热处理、表面处理、建材、电子、材料、轻工、日化、制药等诸多行业领域。

In metallurgical industry, heating furnace is a device (industrial furnace) to heat material or workpiece (usually metal) to roll into forging temperature.

The heating furnace is used in many fields, such as oil, chemical industry, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemical, pharmaceutical and so on.
