[0058] Such as figure 1 , figure 2 As shown, the figure only shows a part of the modular structure of the convection section, and there are other old modules on the upper and lower parts; and the figure is a simplified drawing, and the heat exchange tube bundles 1 are not connected in the figure. In fact, The heat exchange tube bundles 1 are connected by elbows, that is, the materials flow in the coils.
[0059] A modularization method for the convection section of an ethylene cracking furnace. The method uses the first supporting column 6 to make use of the old and prefabricates the components in the convection section of the ethylene cracking furnace into an integrated convection section module according to design requirements. The convection section module and the first supporting column 6 are fixedly connected on site to complete the modular transformation of the convection section of the ethylene cracking furnace.
[0060] The specific steps of the method are:
[0061] Step 1...
