Abstract
A nozzle box includes first and second nozzle box halves which are bolted together. Each nozzle box half includes a nozzle ring segment that carries nozzles along its entire 180° arc, so that when the nozzle box halves are joined together a nozzle box is formed with no discontinuities of nozzles around its 360° circumference. The nozzles carried on each nozzle ring segment communicate with inlet ports, and associated passages which are perpendicular to the nozzle box exit plane.
