Patent number: 9074821Abstract: A heat exchanger for cooling reaction gas. A cooled tube receives hot reaction gas from a hot, uncooled tube. The cooled tube comprises a cooled inner tube and a tubular jacket that extends about the inner tube. A tubular connection is disposed between the uncooled and the cooled tubes, and includes a fork-shaped inlet head via which the inner tube is in communication with the uncooled tube. The inlet head is provided with an outer tubular section and an inner tubular section between which is disposed an intermediate space filled with heat-insulating material. The outer tubular section is connected to the tubular jacket. The inner tubular section is spaced slightly axially from the inner tube and is provided with an edge region that juts outwardly and is spaced slightly axially from the inner tube, this slight axial spacing being equal to or less than a maximum thermal expansion of the inlet head.Type: GrantFiled: June 16, 2010Date of Patent: July 7, 2015Assignee: BORSIG GMBHInventors: Carsten Birk, Michael Vogt, David Todd Eisenhawer

Patent number: 7900969Abstract: Connector between a reaction pipe and a cooling pipe and method for connecting a reaction pipe to a cooling pipe. The cooling pipe is a double pipe having an inner pipe, disposed in the extension of the reaction pipe, and an outer pipe that surrounds the inner pipe to form an intermediate cooling space between them. A supply chamber is connected to the cooling space for supplying coolant thereto. A transition piece, connected to the reaction pipe, has a fork-shaped end portion composed of an inner portion and an outer portion with heat-insulating material between them. The outer portion is secured to the base of the supply chamber coaxially relative to the longitudinal axis of the cooling pipe. The supply chamber, transition piece and half shells form a prefabricated unit. An inner tube section is welded to, and extends out of, the supply chamber and is aligned with the inner portion of the transition piece.Type: GrantFiled: August 7, 2009Date of Patent: March 8, 2011Assignee: Borsig GmbHInventor: Carsten Birk
