Abstract
PURPOSE: To reduce exhaust loss by making the length and the mean radius of the vanes at lower pressure final stage different each other to obtain an optimum exhaust flowing velocity, in a steam turbine equipped with a plural number of vanes at lower pressure final stage.
CONSTITUTION: The steam having worked in a high-pressure turbine is introduced into low-pressure turbines 2 and 3, passing through a crossover pipe 1, and flows as shown by the arrow. When the steam in equal amount is allowed to flow into the inlet parts 4 and 5 of turbines 2 and 3 respectively, and a fixed amount of steam is extracted in every hours at the on-way stage end 6 of the turbine 2, the discharge amount 7 less by the extracted amount is discharged from the turbine 2. From the turbine 3, the discharge amount 8 equal to the inflow amount is discharged. Thus, a valid efficiency can be obtained by varying the vane lengths of vanes 9 and 10 at the low pressure final stages of each turbine 2, 3, according to the discharge amount to form proper annular band area.
