燃料气流直径的影响:气流直径越大，完全混合的时间越长。为了加速混合，可以将大股气流分成若干小股气流。这就是一些大功率的燃烧器有多个燃料气喷嘴的原因。
The effects of the diameter of fuel air airflow larger diameter, the longer the complete mixing. In order to accelerate the mixing, the large strands of airflow can be divided into a number of ***all strands of air. This why some high-power burners h***e multiple fuel gas nozzles.
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.
台车式加热炉是加热炉系列中常见的一种加热设备，台车式加热炉的结构简单，比较通用，而且操作容易，适合于钢铁、石油、化工等多个产业。
The trolley type heating furnace is one of the most common heating equipment in the series of heating furnace. The structure of the trolley type heating furnace is simple, common and easy to operate. It is suitable for many industries, such as steel, petroleum, chemical industry and so on.
