Over 60% improved 2-sigma moisture profile and savings in energy with Valmet IQ steam profiler

Excellent results achieved

The installation was completed in the second half of 2021. Significant benefits were immediately realized. The moisture profile 2-sigma improved by more than 60%, and the sheet dryness increased by over 1.5%. The energy consumption level greatly decreased as a result.

‘The steambox installation and commissioning were carried out according to the schedule. After putting the steambox into use, we realized its performance is very good. The moisture profile improved significantly, far beyond our expectations. The cooperation with the Valmet team was also very smooth during project execution. It was a good experience for us.’ Mr. Fu Zhenzhong, Equipment Dept. Manager, Jingxing Paper.

The Valmet IQ Steam Profiler is a multi-zone steambox system that provides unique profiling accuracy through its electromechanical actuator with position feedback. It features advanced steam injection technology that maximizes steam absorption efficiency and temperature increase to provide better dryness after the press section. 

Working towards the same goal 

The project execution was very smooth. Despite the pandemic restrictions with travel limitations and uncertainties, Valmet’s project team managed to work according to the schedule and delivered on time. This was made possible by proactive and open communication both internally and externally.

‘We are happy that our solution significantly improves Jingxing’s end-product quality and energy consumption level. Valmet is committed not only to moving towards carbon neutral operation, but to also help our customers to achieve the same.’ says Chen Bin, Project Manager, China, Automation, Valmet.
