摘要

The BraSiC process has been developed for brazing SiC based materials in order to manufacture large and/or complex industrial components. In the field of high temperature heat exchanger, CEA and BOOSTEC are developing compact silicon carbide heat exchangers, especially for use at 950℃ in corrosive environment in the context of hydrogen production. The role of CEA is on one hand to develop the brazing process and new braze materials associated to thermo-mechanical, corrosion studies, etc. and on the other hand to design heat exchangers and to investigate their thermo-hydraulic and thermo-mechanical performances. The role of BOOSTEC S.A. is to set up high performance and cost effective ceramic process to manufacture sintered silicon carbide corrugated plates. To that end, the BraSiC process has been optimised and successfully applied for the manufacturing of a mock-up of a silicon carbide heat exchanger (200×200×100 mm~3, 360 channels). Results of thermo-hydraulic tests performed under air in steady flow at 510℃ and up to 7 bars are satisfactory and show a good correlation between measurements and calculations. Currently, these developments are continuing in order to optimise the heat exchanger power and the brazing process to realise a compact SiC heat exchanger-reactor. The objective is more ambitious with a higher expected thermal efficiency, at 850℃ and 8 bars (European project HYCYCLES).
