A Study on Performance Estimations for Hot Water Turbines : Turbine Performance

Abstract

A Series of tests, including nozzle single tests, blade single tests and single-stage turbine tests, are conducted to study the practical applications of hot water turbines. Hot water turbines are considered to be very useful for waste heat recovery plants and geothermal power plants. In this report, single-stage hot water turbine performance data are presented. A hot water turbine performance estimation method covering both nozzle and blade performance is introduced, and this calculation is shown to accord well with the turbine performance test results. Further, it is confirmed both theoretically and experimentally that a high nozzle inlet pressure and assist steam improve turbine performance.
