Abstract
Abstract This invention provides a moisture separating and steam reheating apparatus having a tubular shell structure, a rectifying device for moist steam, a moisture separator and a steam reheater disposed in parallel to each other in the shell structure, a plurality of steam inlets mounted on a side wall of the shell structure and a plurality of steam outlets formed on another opposite side wall of said shell structure, so that steam can flow substantially straight in the horizontal direction in the shell structure from the inlets to the outlets to remove moisture in the steam and to be reheated at a superheated temperature at a low pressure loss of the actuating steam.
