  • Double-fired processing furnace
    Patent number: 7060164
    Abstract: The present invention concerns a processing furnace used by the oil industry to heat feedstocks that are to be treated thermally, which is provided with bi-pivotal support columns to carry the radiation exchange tubes which form the coil of radiation exchange tubes. The support columns are provided with a lower bearing and an upper bearing means, which pivot, respectively, on a lower support and an upper guide, in such a way that all the stresses from the support and the radiation exchange tubes are transmitted to the base, causing no thermal stress from bending momentum to be transmitted to the base of the furnace.
