Reduce steam consumption

• Thermal energy consumption accounts for a significant proportion of total production costs. 
• Steam consumption for drying paper is enormous and the biggest driver.
• A considerable amount of steam is also required for the preparation of mass starch.
• Steam application technologies are also significant steam consumers. Outdated steam boxes often work inefficiently and consume far too much steam.

With our know-how, products and solutions, we can help you to reduce thermal energy consumption as follows - and all while maintaining or even improving product quality:

• Reduction of steam consumption for drying paper:
  • Dry content increase in mechanical dewatering. 
  • Improvement of the sheet formation for more efficient thermal drying.
• Reduction in steam consumption for starch processing.
• Optimization of existing or installation of new steam application technologies.

All projects presented…

• ... show that it is possible to save resources while reducing production cost.
• ... achieved consistent or even improved product quality.
• ... have a return on investment of a few months only taking into account the overall added value achieved.
• ... have been implemented many times - no prototypes or trial installations.

TARGETS ACHIEVED

• Reduction of steam consumption by 0.04 t/t paper.
• This results in total reduction of 11,600 tons of steam per year.
• Same or even improved product quality.
• Return on investment within a few months. 

TARGETS ACHIEVED

• Higher dry content of 1.5% after the last press.
• Improvement of sheet formation by 17%.
• Steam consumption reduced by 8 % or 25,000 tons per year.
• Same or even improved product quality.
• Return on investment within a few months.

TARGETS ACHIEVED

• Steam consumption in drying section reduced by 9% (despite additional steam blow box).
• 8,600 t less steam in total with the same production.
• SSV also enables additional production and better availability thanks to significantly improved profiles.
• Same or even improved product quality.
• Return on investment within a few months.

TARGETS ACHIEVED

• Increased dewatering capacity increases mechanical dewatering and reduces the need for thermal energy.
• 19 % increase of wire speed (+ 13m/min).
• 6.9 % dryness content increase before couch roll.
• 57 % sheet temperature increase before couch roll (+29 °C).
• Same or even improved product quality.
• Return on investment within a few months.
