Steamdry is pleased to announce its participation in the 15th IEA Heat Pump Conference, where our partner AIT Austrian Institute of Technology will present joint work on advanced heat recovery and drying technologies.
The presentation, titled “Heat recovery with steam compressor: Dynamic model of a superheated steam drying system to evaluate efficient system operation,” will be delivered by Michael Pölzl (AIT) on Friday, May 29 from 15:30 to 15:45 in the Festsaal. It is part of the session “HTH11 + AIP2 Techno-Economic & Environmental Assessment of High Temperature Heat Pumps and Adaptation of Industrial Processes.”
This contribution, developed by AIT in collaboration with Piller Blowers & Compressors and Wageningen University & Research, focuses on superheated steam drying (SSD) as an innovative alternative to conventional drying processes in the pulp and paper industry.
SSD offers strong potential for improving energy efficiency, reducing emissions, and enhancing product quality. A key element of the system is the use of a steam compressor, which recovers latent heat from excess steam and upgrades it to the required temperature and pressure levels for reuse within the drying process.
To better understand and optimize this complex system, a dynamic model has been developed to simulate the transient behavior of the dryer, steam compressor, and auxiliary components such as heat exchangers and electrical heating. This model makes it possible to evaluate how different operating conditions—such as temperature levels and the presence of air in the steam cycle—affect overall system performance and efficiency.
The results demonstrate how such modeling tools can support the design and operation of superheated steam drying systems, enabling more efficient and reliable integration into industrial processes.
Through its partners, SteamDry is proud to contribute to the development of next-generation drying technologies and to support the transition toward more energy-efficient industrial solutions.
