在油气生产中，加热炉的基本要求如下：
生产效率高。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 c***umption, and s***e maintenance costs.
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.
台车式加热炉的组成包括加热炉本体和余热回收系统。余热回收系统中有一个空气预热器,空气预热器是又由非冷凝式空气预热器和冷凝式空气预热器两段组成。
The trolley heating furnace c***ists of a heater body and a waste heat recovery system. There is an air preheater in the waste heat recovery system. The air preheater is of a non-condensing air preheater and a condensing air preheater.
