在油气生产中，加热炉的基本要求如下：

生产。在保证质量的前提下，燃料加热速度越快越好，这样可以提高加热炉的生产效率，减少炉子座数或缩小炉子尺寸。快速加热还能降低金属的烧损和单位燃料消耗，节约维护费用。

In the production of oil and gas, the basic requirements of the heating furnace are as follows:

The production efficiency is high. Under the premise of ensuring the quality, the faster the heating of fuel is, the better it can improve the efficiency of heating furnace, reduce the number of stoves, or reduce the size of the furnace. Rapid heating can also reduce the burning loss of metal and unit fuel cumption, and s***e maintenance costs.

加热炉的分类:

1.有纯加热炉，如常压炉、减压炉等；有加热炉反应炉，如裂解炉、焦化炉等。

2.按传热方式分类：有纯对流式炉、辐射对流式炉和辐射式炉。

The classification of the heating furnace:

1. there are pure heating furnaces, such as ctant pressure furnace, pressure reducing furnace, and so on; there are reheating furnace reaction furnaces, such as cracking furnace and coking furnace.

2. classified according to the heat transfer mode: there are pure convection furnace, radiant convective furnace and radiant furnace.

靠炉底或水冷金属梁的上升、前进、下降、后退的动作把料坯一步一步地移送前进的连续加热炉。炉子有固定炉底和步进炉底，或者有固定梁和步进梁。

Depending on the action of rising, advancing, falling and backing of the furnace bottom or the water-cooled metal beam, the material is transferred to the continuous reheating furnace step by step. The furnace has fixed furnace bottom and walking furnace bottom, or there are fixed beam and walking beam.

蓄热式加热炉的辐射传热：辐射传热是物体热射线的传播过程，温度越高，辐射能量越大，此种传热存在于炉气对炉壁、炉气和炉壁对钢坯表面。

Radiation heat transfer of regenerative reheating furnace: radiation heat transfer is the propagation process of heat radiation of the object, the higher the temperature, the greater the radiation energy, the heat transfer exists in the furnace wall, furnace gas and furnace wall to the surface of the steel billet.
