The project is part of a global research action by the energy industry sector, aiming at the implementation of a high efficiency,
environmentally friendly Externally Fired Combined Cycle (EFCC) based on an Ultra High Temperature Heat Exchanger (UHTHE) for application temperatures up to 1500 C. Ceramic Matrix Composites are currently the most promising material class for this application. The expected advantages of the new system are higher efficiencies compared to concurrent technologies, low costs compared to the benefits and a significant reduction of critical emissions.
The main deliverable of the proposed project is a produceable design of the internal part of the planned Ultra High Temperature Heat Exchanger (UHTHE) module. The sub-critical components consist of heat-exchanger tubes, carrier plates and implies the need for permanent joints and hot-gripping systems. The project will be based on three promising state-of-the-art materials, which are all available within the project The materials are one discontinuously reinforced CMC (DR-CMC) and two continuous fibre reinforced materials (CFR-CMC). At the end of the project, one design solution will be selected for prototype testing in a subsequent project.
Several innovations will result from this project, which will promote the service introduction of CMC-materials. Main innovations to be expected are reliable software codes fulfilling industrial needs for life-time prediction of CMC components, reliable FE-modeling of brazed joints for ultra high temperature application and highly improved hot-gripping systems for un-fastenable ultra high temperature joints.
The chosen approach will guarantee the best currently possible performance of the technologies, software codes and modelling methodologies to be developed. Therefore, the spin-off potential to other industrial applications (e.g. gas turbines, industrial processing, transports, ...) is very. Higher efficiency, simplified design and therefore reduced manufacturing, installation and maintenance costs are the main benefits for industry.
