FIELD: power industry.

SUBSTANCE: invention relates to a steam power plant (1), including a steam turbine (2), a steam pipe (5), hydraulically connected to the steam turbine (2, 2a, 2b) and designed for the steam passing, a valve (3, 4, 6, 7) fixed in the steam pipe (5) and designed to change volume flow of the steam in the steam pipe (5). In the operating mode, a spindle leak steam is formed in the valve (3, 4, 6, 7), hydraulically connected to a pipeline (11, 12, 13, 15, 17, 18, 19, 20) of the spindle leak steam, a collector (16) of the spindle leak steam, hydraulically connected to the pipeline (11, 12, 13, 15, 17, 18, 19, 20) of the spindle leak steam characterized in that in the pipeline (11, 12, 13, 15, 17, 18, 19, 20) of the spindle leak steam an armature is installed (14a, 14b). The collector of the spindle leak steam is made in the form of a condenser (8). Also, a method for operating the plant is also provided, characterized in that the armature (14a, 14b) is opened with the presence of the spindle leak steam in front of the armature (14a, 14b) and is again closed with the absence of release of the spindle leak steam from the valve (3, 4, 6, 7).

EFFECT: simplify the design and increase reliability in operation.

Turbine bypass // 2542655

FIELD: power industry.

SUBSTANCE: turbine bypass includes a bypass path selectively used for supply of hot gases to a gas cooler and a backfill of heat absorbing elements, which is placed on the bypass path before the gas cooler. The backfill includes heat absorbing elements located between perforated supporting layers for uniform scattering of bypass steam on side parts of the heat absorbing elements in the backfill.

EFFECT: invention allows reducing temperature of bypass gases before they are supplied to the gas cooler.

SUBSTANCE: two-rotor air compressor for combined-cycle plants is proposed, its common housing hosts a low-pressure rotor coupled with a recovery steam turbine set on the side of the atmospherical air suction into the compressor and a high-pressure rotor coupled with a gas turbine set on the compressor discharge side. The air compression rate in the low-pressure compressor ε1 is defined on the condition that the recovery steam turbine output is equal to the low-pressure compressor output, and the air compression rate in the high-pressure compressor ε2 is equal to ε2=εε1, where ε stands for the total rate of air compression in the two-rotor compressor.

EFFECT: invention is aimed at increasing the maximal output of combined-cycle plants.
