The Clyde Bergemann Anthony Ross Stacked Air System (SAS) is the cutting edge combustion technology for NOx emission reduction in pulverized coal fired units. It utilizes staged low pressure faster mixing over-fire air to achieve a more uniform mixing in the furnace and to improve combustion performance. The Stacked Air System utilizes a patented inboard and outboard design to introduce a swirl inside the furnace to reduce emission with minimal impact on CO and LOI production. Computational Fluid Dynamics modeling of each boiler will provide a customized location of the over-fire air ports to optimize combustion and reduce emission.

The Clyde Bergemann Anthony Ross Stacked Air System has a proven track record with over 30 installations in the challenging Pulp and Paper industry for Chemical Recovery Units. Extensive experience coupled with customized application will guarantee most advanced in-furnace technology to reduce emission and increase pulverized coal fired boiler performance.
