Controlling sulfidity in a modern kraft pulp mill, case study

Creating valuable side streams from the kraft pulping process can disturb the sodium sulfur balance. Valmet has expanded the sulfidity control toolbox with a process to oxidize sulfur containing CNCGs to relatively concentrated sulfuric acid. A white paper describes the first full-scale plant using this process.

Improve safety at your boiler with a furnace inspection camera

Maintaining safe, efficient and environmentally compliant boiler operations is very important. Valmet's Mobile Furnace Inspection Camera System improves the boiler operation decision-making process.

Valmet Calender Roll Cover CL-EC for extreme calendering

Under extreme conditions, when load and speed are high and cover durability is tested, special covers are needed. The Valmet Calender Roll Cover CL-EC (extreme conditions) is designed to increase heat dissipation from dynamic loading and resist barring and wear.

Valmet Steam Separator PV saves energy at BHW Beeskow, case study

Installing a Valmet Steam Separator PVmechanical steam separator at BHW Beeskow Holzwerkstoffe fiberboard plant after the Defibrator allowed 1.4MW/h more electricity to be produced in their steam turbine.

Super fast slitter positioning system in only five seconds!

Positioning takes very little time. The significantly shorter positioning time benefits paper and board production lines by minimizing winder downtime and increasing winder capacity and availability.

Improving recovery boiler cooling and washing practices

The length of a mill outage is frequently set by the time needed for recovery boiler cooling, washing, inspections and repairs. The ways cooling and washing are carried out can be optimized so that the total outage time can be reduced.

Valmet composite cover for wire, felt and paper lead rolls

Sustainability in district heating through pellet firing

All efforts to decrease the environmental load in power generation are needed to reach sustainability targets. Using wood pellets – carbon neutral, high-quality biofuel – offers a viable alternative in district heating. Read more about the pellet-fired heating plant in Tampere, Finland.

360°Rolls - performance up, costs down

By questioning their current operating models, paper mills greatly increase the chances of success in the search for lower costs, better availability, and higher efficiency. Valmet’s 360°Rolls approach enables papermakers to achieve better results with a 360° view of rolls and the roll environment.

More energy from the existing equipment

A fifteen percent capacity increase and more operating hours with only minor investments – this is the achievement of the energy company Mölndal Energi in Sweden. The company has greatly improved the production in their new biomass-fired boiler since it was supplied by Valmet in 2009.
