A moisture separator reheater (12) comprising a wet steam region (32) for containing moisture laden water vapor and a dry steam region (36) containing dry water vapor. An entrance tube (74, 118, 152, 174) is fluidly connected to the wet steam region. Swirlers (76, 134, 178) or similar deflection structure (170, 172) are provided for separating the flow of steam through the entrance tube into liquid and vapor streams. A concentric exit tube (86, 136, 176), or similar structure (158), directs the flow of the vapor stream into the dry steam region while bypassing the liquid stream. The tubes and associated structure are preferably arranged in a steam dryer assembly bundle (54) having a lower plate (128), a plurality of entrance tubes secured to the lower plate, and an upper plate (126) through which the exit tubes pass. The wet steam enters the tubes of the dryer assembly bundle from the steam region below the lower plate, and the liquid extracted during demoisturization is directed into a region (34) between the plates, while the dry stream flows through the exit tubes into the dry steam region above the upper plate.
