Valmet extends its quality control systems expertise to the paper and board machine forming section with the introduction of the Valmet IQ Dryness Measurement (IQ Dryness), as the company says in the press release received by Lesprom Network.
Utilizing microwave technology, the IQ Dryness measures the water layer thickness on the web, which can be used to calculate the web dry content. As well as removing most of the water, the majority of paper properties are also developed in the forming section.
The inclusion of IQ Dryness in Valmet's paper quality control family opens new possibilities as it helps to close the information gap between the stock approach system and dry end quality sensors.
"Perhaps the biggest effect is the better management of dewatering. This has a great influence on the amount of the subsequent drying energy needed with potentially big cost savings in paper production. An increase of just 1% in dryness before the dryer can reduce the amount of energy needed to evaporate the excess water by approximately 4%," says Marko Toskala, Director, Quality Management Solutions, Valmet.
Valmet is the leading global developer and supplier of process technologies, automation and services for the pulp, paper and energy industries.
