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 2 MW BFI own burner test facility.
