Title: Heat exchanger
Inventor: GOODON DABURIYUU FUEN
IPC: F28F1/00
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To restrict corrosion which is caused by high temperature and ensures long term use of a heat exchanger by surrounding a plurality of coil-shaped heat exchange tubes, and providing a film-shaped liner isolating a space where the heat exchange tubes are disposed from a space around the foregoing space. SOLUTION: High temperature combustion gas produced in a burner flows in from an upper part of a combustion gas passage formed with an inner liner 107 and an outer liner 108, and flows out from a lower portion. Since a baffle plate 106 is disposed in a central air gap in a heat exchange tube 103, the combustion gas slowly flows compared with the case where there is existent a hollow cavity. Accordingly, there is performed heat exchange between water flowing in the heat exchange tube 103 and the combustion gas flowing through the outside of a combustion gas passage of the heat exchange pipe 103. In such a manner, the heat exchanger is not directly heated by the burner but is indirectly heated so that adhesion of harmful gas and combustion oxide and corrosion of the constituent members are prevented to prolong the life.
