Abstract

The invention relates to a power system and m. used on maneuverable thermal power plants with peak-accumulating extensions. The purpose of the invention is to increase the efficiency of unloading the power plant. Cooled in the battery 6 pairs through the pipeline 9 is fed to the input of the regenerator 10, where it is cooled by evaporation of condensate. The generated steam is sent from the generator through line 15 with valve 16 to the flow part of the installation. 1 il.

The invention relates to a power system and can be used on maneuverable combined heat and power plants with peak storage enclosures.

The aim of the invention is to improve the economy.

The drawing shows the power plant for the implementation of the proposed method of unloading.

When unloading the power plant, the valve 8 is opened and part of the fresh steam flow from the steam line 5 to the steam turbine 1 via the steam line 7 is diverted to a heat accumulator 6, from which the steam line 5 is fed to the regenerator 10, to the inlet of the last heated the medium is fed through line 13 with a valve 14 condensate of steam that has been spent in turbine 1 and

condensed in condenser 3 of

The installation contains a steam turbine 0 of condensate line 4 immediately after condensate 1 with electric generator 2 and condenser RS 3, generates secondary steam and direction 3 with condensate line 4, to the input of which it is fed from regenerator 10 via line 15

steam pipe 5 of fresh steam is connected, co-with valve 16 to steam turbine 1. Condensed with heat accumulator 6 pa-Densat of heating steam from regenerator 10

The conduit 7 with the valve 8, to the outlet of 15 is retracted through the steam pipe 11 with the valve 12.

battery 6 with steam pipe 9 is connected. Formula of the invention rto heating medium input of the regenerator 10, which method of unloading energy ustyyhodod through the heating medium connection by reducing steam consumption on whose steam line 11 with a valve 12, in a heated medium, the input of the regenerator 10 is a turbine approach with supplying part of it for cooling in a heat accumulator and connected to the condensate line 4 by steam line 13, characterized in that with the valve 14, and the output of the regenerator 10 to the steam turbine 1 line 15 with the valve 16. The method of unloading the power plant is carried out as follows. In order to increase efficiency, the vapor cooled in the battery is further cooled by evaporation of the condensate, and the generated steam is fed to the flow part of the installation. When unloading the power plant, the valve 8 is opened and a part of the fresh steam flow from the steam line 5 to the steam turbine 1 via the steam line 7 is diverted to the heat accumulator 6, from which the steam line 9 is fed to the regenerator 10 input served on line 13 with a valve 14 condensate steam, spent in the turbine 1 and the turbine inlet with supplying it for cooling in a heat accumulator and steam condensation, characterized in that In order to increase efficiency, the vapor cooled in the battery is further cooled by evaporation of the condensate, and the generated steam is fed to the flow part of the installation.
