燃料气与空气的流动方式 主要可以归纳为四种，燃料气喷射到静止的空气中；燃料气和空气平行流动；燃料气和空气流动时相互之间有一定的夹角；燃料气和空气呈旋流运动。

The flow of fuel gas and air can be divided into four main types, the fuel gas injected into the air; the fuel gas and the air flow in parallel; the fuel gas and the air flow between a certain angle; the fuel gas and air in a cyclone movement.

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.

台车式加热炉的结构一般是由辐射室、对流室及烟囱组成。辐射室也就是燃烧室，将燃料放进辐射室进行燃烧产生高温，以对传播热的方法持续将局部热量传给对流室炉管内活动着的油品。然后通过对流室和烟囱将油品和烟中的热量进行吸收，传递给产品。

The structure of the trolley type heating furnace is generally of a radiation chamber, a convection chamber and a chimney. The radiation chamber is also the combustion chamber, which puts the fuel into the radiation chamber for combustion to produce high temperature, and continuously transfers the local heat to the oil moving in the convection chamber furnace tube by means of heat tran***ission. Then the heat and oil in the oil and ***oke are absorbed and tran***itted to the product through the convection chamber and the chimney.
