Abstract

PURPOSE: To improve thermal efficiency, by flowing a mixed steam, generated in the connection of packing leak steam line and the steam line from the other stage, into the rear stage.
CONSTITUTION: Before connecting a packing leak steam line 3, in a front side gland part 2 of a high pressure turbine 1, to a rear stage part 5, a steam line 6, which is supplied from the other stage part at higher and lower temperature than said steam, is connected to prepare a mixed steam 7, which is collected and supplied to the rear stage part 5 as a stage main steam flow 8. At this time, since the temperature of the mixed steam 7 is lower than that of the packing leak steam 3, a temperature difference from the casing side becomes small, and a thermal deformation is avoided. In addition, an orifice 9 or chamber 10 may be provided if necessary for the preparation of the mixed steam 7, and it is preferable to install thermocouple 11, 12 in the casing side for the monitoring of temperature difference in order to increase a reliability.
