Boosting efficiency with zeolites

04. April 2017

A while ago ERK has completed a R&D-Project on the integration of zeolites into our boiler systems to boost thermal efficiency. The project included the testing of all components in a small cogeneration plant located at the University of Applied Sciences Wildau

Zeolite, hot stones, are microporous structures, which behave like sponges. Their immense inner surface, 1,000 m2/g, absorbs water and simultaneously releases heat. This feature enables an upgrade of low temperature heat sources. Possible applications for zeolites in boiler systems and industrial plants include flue gas condensation and thermal energy storage. Zeolites absorb the water in flue gases while simultaneously increasing its temperature level. When used for thermal energy storage it allows long-term storage and mobile storage systems.

We would like to thank the Federal Ministry of Economy and Energy for its generous support and are looking forward to first commercial projects.
