Explosion or pressure wave cleaning of black liquor boilers in the paper industry


Optimal performance for the paper industry

The black liquor boiler plays a key role in the recovery of chemicals and the efficient use of energy in the paper industry, as raw materials are converted into valuable raw materials during the boiling process. To ensure maximum system availability, the black liquor boiler, heat recovery steam generator, electric filter, and other steam boilers must be as free of deposits and contamination as possible. With our PressureWave+™ and CloudEx™ cleaning processes, you can rest assured that your paper mill equipment is always available and can run efficiently at full capacity. Build on our experience.
