XXL size recovery boilers - safety and availability, case study
XXL size recovery boilers have operated since 2004, reaching or exceeding all process requirements. The XXL size recovery boilers are typically designed for high dry solids content, high energy efficiency, low air emissions, and environmentally friendly process solutions. Those boilers burn Non-Condensable Gases (NCG) and other side streams coming from the other parts of the mill, and therefore the XXL size recovery boilers are very important in targeting for odorless pulp mills.
