1000th Black Belt shoe press belt runs for ~200 days, case study
Valmet Black Belt features excellent wear resistance, stable structure and long run times. See how these features affected Papierfabrik Palm's success with PM6.
Increase uhle box dewatering, reduce needed vacuum - case studies
The new coating and uhle box cover also improve runnability, moisture profiles and felt lifetime. The technology is unbeatable and several references prove it.
Digital hydraulic concept reduces cost and increases reliability
By using digital hydraulics, fragile and expensive proportional valves are replaced with multiple inexpensive and robust on/off valves. The results include higher reliability, lower energy usage, more accuracy in machine movements, fewer shutdowns, less lost production and lower initial investment and spare parts carrying cost.
Circulating fluidized bed (CFB) evolution from coal to biomass
Circulating fluidized bed (CFB) technology has adapted to market needs over the last thirty years, from high-ash coal to low-calorific-value biomass, and from petcoke with a high sulfur content to waste fuel with a high chlorine content. CFB technology has proven its capability to adapt to changing technical requirements.
Smooth extended nip press (ENP) change-out, a case study
Valmet supervised the change-out of an ENP module. This included a preliminary NipScan and audit of the press and hydraulic units to spot potential problems.
Production of sulfuric acid from incineration of pulp mill NCGs
The production of sulfuric acid from pulp mill NCG enables a bioproduct mill to become nearly self-sufficient in sulfuric acid usage. Sulfate led to the mill's effluent treatment plant is reduced and the sulfate load to nearby waterways is decreased drastically. This innovative plant can produce sulfuric acid and bisulfite simultaneously depending on the requirement. The internal recycling of chemicals can reduce purchasing by 350 truckloads of acid per year.
Safety Tip: Chromium-free Yankee cylinder surface metallization
Valmet has launched a product and application process for the metallization of Yankee cylinders that is 100% chrome free, Infinikote-2. There is absolutely zero generation of the potentially carcinogenic hexavalent chromium during application.
Valmet Superheater FuelDiet KCl Corrosion Management solution
Valmet Superheater KCl Corrosion Management can reduce fuel costs by using low-priced fuels without increasing the risk of superheater corrosion.
Future-proofing valve control
New distributed control systems (DCSs) reduce operating expenses in a range of cement production processes, including the operation and maintenance costs of valves. Valmet explains the importance of DCSs and highlights advances in valve and pump technology
Headbox case study – Overcoming newsprint mill speed limit
The mill was concerned about speed limitations due to the current headbox status. They asked Valmet to diagnose the situation and recommend a course of action.
