Such ovens are so called because of its shape. It is generally used in crude units and vacuum. It has side burners and radiant tubes in the area are placed horizontally along the vertical wall and the roof of it. The tubes located in the area often called radiant wall tubes.

In most furnaces many burners on both sides of it, which favors the distribution of heat within the home. In the center of the home is common to find a wall of radiation consists of refractory material (bricks). The burner flame is limited to the side walls, the walls ladrilllo refractory is heated and radiates heat to tThe tubes. This provides the advantage that the flame does not touch the tubes, which could generate a localized hot zone with the subsequent formation of coke inside the tubes. The coke acts as an insulator and the liquid or gas process can not remove enough heat to move through this point, causing overheating of the tube and heat resistance may exceed the metal, causing the rupture of the tube.
