DOUBLE-FIRED PROCESSING FURNACE AND BI-PIVOTAL SUPPORT COLUMN THEREFOR

摘要

The present invention concerns a processing furnace used by the oil industry to heat feedstocks that are to the treated thermally, which is provided with bi-pivotal support columns (4) to carry the radiation exchange tubes (10) which form the coil of radiation exchange tubes. The support columns (4) are provided with a lower bearing means and an upper bearing means, which pivot, respectively, on a lower support means (6) and an upper guide means (8), in such a way that all the stresses from the support means (4) and the radiation exchange tubes (10) are transmitted to the base (12), causing no thermal stress from bending momentum to be transmitted to the base (12) of the furnace.
