Abstract

Work procedure to improve the degree of thermal efficiency of a steam turbine installation under partial load, with preheating of the feed water by extracted steam to a maximum of 55% of the theoretically possible increase in the enthalpy corresponding to the steam pressure i live on the enthalpy of the condensates, characterized in that up to a fixed partial load, preferably half a load, the entire flow of the feed water corresponding to the partial load fixed after the last preheating is heated additionally by extracted steam whose pressure is higher than the vapor pressure of the last stage of proheating.
