Title: Heating tube for heat exchanger
Inventor: TANAKA YASUHIRO
IPC: F28D7/12
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To enhance heat transmission efficiency by employing ceramic heating tubes for a heat exchanger exchanging heat on the inside and outside and forming a plurality of fins on the inner surface thereof and to save the space by decreasing the ratio of tube length/thickness thereby shortening the length of the ceramic tube. SOLUTION: A heating tube 1 comprises a ceramic tube provided, on the inner surface thereof, with a large number of fins 2 integrally. Outer surface of the heating tube 1 is exposed to high temperature gas and gas to be heated is passed on the inside thus exchanging heat. Consequently, heat transfer area of each fin 2 is increased and thermal efficiency can be enhanced. Alternatively, a curved face sealing part may formed continuously to one side of the heating tube 1 and fed with the gas to be heated from an inner tube 4 through the air gap between the inner tube 4 and the heating tube 1.  A hollow part 3 where the fin 2 is not present is formed in the center of the inner surface at the intersection of the fins 2, i.e., the sealing part, in order to prevent the gas to be heated from striking against the sealing part directly thus relaxing thermal stress on the inner and outer surfaces.
