Research and Development of Improved Efficiency Small Steam Turbines (IESST). Technical Progress Report, Phase I, 16 April-31 December 1979

摘要

Product Statistical Bulletins of the National Electrical Manufacturers Association (NEMA) and Turbodyne's shipment records over a 10-y period were researched to determine quantities installed and to define general parameters of design. Engineering studies were conducted to determine the optimum turbine design to meet the defined design parameters. Two conceptual designs plus an added variation of one design were completed together with designs of gearing required to provide speeds compatible with driven equipment speeds. The calculated performance of the recommended design and currently available small steam turbines were compared and a life cycle cost analysis was conducted to determine the economic competitiveness of the new design.
