Abstract:
An auto-reheat system for use with a Rankine cycle turbine engine having an expansion cycle, said turbine having an admission port to admit heat energy, obtained from a heat source, to a main path through the turbine, the heat energy entering said turbine embodied as high temperature high pressure vapor, said turbine equipped with the necessary blading and stages to permit isentropic expansion of the vapor therethrough, beginning through an entry zone adjacent the admission port, the entry zone containing high pressure high temperature vapor, through a subsequent zone containing lower temperature lower pressure vapor, to an exit port, the auto-reheat system comprising:a conduit having a first end and a second end, the first end for receiving high temperature high pressure vapor originating from the heat source;a manifold connected to the second end of said conduit; anda plurality of injectors located around a perimeter of the turbine and connected to said manifold, said plurality of injectors for injecting the high temperature high pressure vapor received from said conduit into the turbine in an area corresponding to the subsequent zone, the injected vapor increasing the temperature of expanding vapor within the subsequent zone and thereby reducing a volume of moisture condensing therein.
