Study and construction of a ceramic heat exchanger based on an existing laboratory module
Design and construction of a pilot ceramic heat exchanger are presented. This third generation device is made up by putting together 4 silicon carbide modules within a metallic cylindrical casing with an active thermal insulation. The main characteristics are: - thermal efficiency: 0.5 - thermal exchanged power: 125 kW - air mass flow rate: 0.192 kg/s - exhaust gas mass flow rate: 0.192 kg/s with an inlet temperature which could exceed 1200 C. The optimisation of the design and the mastering of the manufacturing processes show that a good techno-economic viability can be obtained. This is confirmed by the results of industrial segment identification (kilns for advanced ceramics, tableware and sanitary ware, kilns for steel heat treating, forge of steel or non-ferrous metal reheating) and market size evaluation. Due to problems of thermo-mechanical behaviour of the ceramic flasks during testing, two stages have to be performed before considering industrialisation: - reliability improvement of ceramic part assembly and flask behaviour - demonstration of a full-size system on an industrial site, with the collaboration of a kiln and furnace manufacturer.
