Abstract
PURPOSE: To seal up a low-pressure gland by low-enthalpy bleed except in start and in stop, by connecting a low-enthalpy bleed branch line to a low-pressure gland steam feed line.
CONSTITUTION: A bleed line 13 extending from low-pressure turbines 11a, 11b is connected to one end of a branch line 14 connected at the other end to a sealing steam feed line 3. A check valve 15, which permits steam to flow only to the sealing steam feed line 3, and an orifice 16 are installed in the line 13. When the pressure of the line 13 exceeds that of the line 3, steam flows into the line 3 from the line 13 through the check valve 15 and the orifice 16 and is then supplied to each gland part of the low-pressure turbines 11a, 11b through conduits 7, 8. At that time, steam leaking from a high-pressure turbine 9 and having high enthalpy is recovered to a low-pressure bleeding line from a gland steam regulator 1 through a valve 18
