Abstract

The findings of the experimental research of the two-stage turbine with the rotor drum arrangement are presented. The thermodynamic efficiency of both stages established by means of the torque measured by a torquemeter as well as the efficiency evaluated from the temperatures is considered. The influence of the Reynolds number on measured parameters is checked. The shaft steam sealing is modelled and the effect of the balancing slots covering on the resultant efficiency is evaluated.
