ABSTRACT:
An auto-reheat system for use with a steam turbine in which a portion of the heat energy supplied to the turbine from a heat source is directed to an ensuing region of the vapor path where the transiting vapor has expanded to such an extent that it begins to become "wet." The portion of heat energy directed to the ensuing region is delivered concurrently with the supply of heat energy to the admission port of the turbine, permitting a higher temperature to be maintained within the transiting vapor and thereby reducing the quantity of moisture developing in the vapor during the latter stages of the turbine expansion cycle. The result is improved turbine energy output and reduced blade maintenance costs.
