REKUKER – Ceramic heat exchanger
Initial situation:
- Steel recuperators are limited in the application temperature.
- Ceramic recuperator burners are suitable for 1,200 ° C, but are only available for small capacities.
- Ceramic recuperator burners are not suitable for dusty atmospheres.
Working topics:
- Process development for the novel ceramic high-temperature recuperator.
- Material development and new joining techniques for ceramic high-temperature heat exchangers.
- Development of specific manufacturing and joining technology.
- Implementation of the new process in technical applications.
Results:
- High energy saving thanks to intensive combustion air preheating.
- Recuperative heat recovery up to the MW range.
- Recuperative combustion air preheating to 800 – 1000 ° C.
- Construction of a demonstrator and test at the 1 MW BFI own burner test facility.
