Main technical features

The air system is central to good recovery boiler performance. Valmet’s Multilevel Air System features staged, interlaced air distribution that efficiently reduces NOx emissions and makes it possible to meet the most stringent emission limits.

Valmet offers mill-wide systems to collect and combust odorous gases. These systems are often integrated with the Multilevel Air System.

A unique feature in the recovery boiler is a rigid cross-furnace screen at the nose arch. It protects the superheater from furnace heat radiation and thus reduces corrosion.

Operator safety and ergonomics play key roles in Valmet’s boiler design, and our boilers feature many solutions that focus on them. Some examples are our systems for automatic cleaning of air ports and smelt spouts, retractable liquor gun systems and safety shields at smelt spouts.
