The VEO boiler design offers the least amount of furnace refractory compared to other designs. The tube and membrane seal welded front and rear walls virtually eliminate all refractory in the furnace, other than localized seals. This design greatly reduces maintenance costs and offers increased unit availability. The furnace sidewalls are tube and membrane construction for the entire length of the furnace to eliminate the possibility of gas bypassing. The outer sidewalls are also tube and membrane design for gas tight construction. This design offers 100% water cooling. The furnace wall tubes of any boiler encounter the highest heat flux. The VEO boiler design, has the shortest furnace wall tubes in the industry. This advantage removes heat from the furnace quickly and extends boiler life. The VEO boiler design has a single lower drum which reduces maintenance compared to other designs that may have two lower drums or headers. The single large diameter drum makes it easier to perform inspections and to maintain lower tube connections. The steam drum includes steam separation equipment.

Complete system used only 1 year. Still installed at Washington State Pulp Mill.
