Energy Saving by Introduction of Thermocompressor to the Container Board Machine

Abstract

Rengo Yashio mill has been engaged in saving energy with all of mill employees and this approach has gained a high reputation from many associations. This report describes approach and effect for installation of thermo compressor, surplus steam recovery system, as one of the energy conservation activities. Even though it was the first study and experience of thermo compressor operation with a paperboard machine of Rengo, we found a means to utilize it by making up the control system with minimum required equipment. Moreover, this system has been operated without any problems in manufacturing process and any additional energy consumption. Although this trial is not finished yet, the steam recovery system with thermo compressor can be very beneficial if the process condition is fitted to the system.
