Recovery boiler optimization - Reduction rate control, case study

A recovery boiler’s main control variables of reduction rate were studied and the performance of the Valmet Recovery Analyzer’s online reduction rate measurement was evaluated in real recovery boiler conditions at Stora Enso Veitsiluoto in Kemi, Finland.

Five questions that will help maximize roll cover effectiveness

Roll cover decisions are complex; the prices, performance characteristics and cover lifetimes vary considerably. Answering these five questions can guide papermakers in making a better choice among today's wide range of roll cover technologies.

Reduce tissuemaking costs and improve profiles with AirCap Heli

Valmet's patented Advantage AirCap Heli reduces the energy consumption required for drying tissue, while improving cross machine profiling and drying uniformity. Results have proven that AirCap Heli can reduce 2-sigma values.

Using iRoll for sheet/roll temperature monitoring, case studies

Valmet iRoll Temperature is an online tool for measuring the temperature profiles of rolls, roll covers and paper webs. These three case studies describe how iRoll technology has helped mills reduce roll cover wear, eliminate cover failure and improve profiles and runnability.

Valmet list of best practices for wet pressing optimization

Wet pressing has an impact all the way from paper machine drying capacity and web runnability to end product properties. The secret of process efficiency often lies in making the right choices for the press section consumables.

Solutions to severe service control valves

Juha Relander, Valmet Finland, outlines the importance of selecting the most appropriate severe service control valves.

Managing wear in severe services

Wear in valves is surely an important concern for plant owners and operators. Eroded valve internals can have a long-term effect on the functioning and profitability of process facilities. Materials such as ceramic reinforced metals can be a good solution to increase component lifetimes in industries such as oil and gas, says Valmet’s Mr Jussi Hellman.
