观察气体燃料从扩散燃烧逐步地改变成半预混燃烧的变化过程可以更加清楚地了解半预混燃烧燃烧，预混燃烧的特点。

The gradual change of gaseous fuel fro*ffusion combustio*semi premixed combustion is observed， and the characteristics of semi premixed combustion and premixed combustion can be more clearly understood.

加热质量好。加热时介质出炉温度需符合工艺要求，****局部过热出现结焦、结炭或危险。

燃料消耗低。站场用加热炉的能量消耗有10～15％消耗于炉子上，节省的燃料对降低单位成本和节约能源都有重要意义。

The quality of heating is good. The heating temperature of the medium should meet the requirements of the process， preventing the local overheating from coking， carbon or explosion.

Fuel c*umption is low. The energy c*umption of the reheating furnace in the station is 10 ~ 15% on the furnace. The fuel s*ing is of great significance to reducing unit cost and s*ing energy.

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 i* forging temperature.

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