| Abstract: | It is evident that the bending deformation of furnace tube of hydrogen manufacturing conversion furnace can lead to accident of burst. It tries to seek for the reasons of bending deformation of furnace tube by analysing the results of temperature of radiation room, temperature of tube and thermal stress and so on. The affection of initial deformation caused by thermal stress on bend deformation is investigated. It is believed that the mal distribution of temperature of the circumference surface of tube plays an important role to deformation. |
