Abstract (en)
[origin: EP1985956A2] The tube plate (100) has a central sheet (11), an exhaust gas-sided tube plate sheet (12), a hydraulic tube plate sheet (13), sealing ring (14), corrosion protection sheet(15) and an outer sheet (16) connected with each other. The sheets (11, 12, 13, 16) are made of metal i.e. stainless steel. The outer sheet is made of corrosion resistant material such as thermoplastic resin e.g. polytetrafluoroethylene. Receiving openings (20) receive tubes of a downstream heat exchanger, where the tubes are made of glass.
