Abstract
A register for use in conjunction with kraft recovery boilers or bark-fired boilers utilizes a pair of shaped damper foils to reduce turbulence and induce laminar flow of air from an associated windbox through a port in the boiler. The foils are mounted for constant minimal separation from an exit nozzle to reduce transitional discontinuities which induce turbulence. A curved plenum is also provided to reduce internal turbulence within the plenum.
