METHOD TO INTENSIFY CONDENSATION OF STEAM IN CONDENSER OF STEAM-TURBINE PLANT Russian patent published in 2013 - IPC F01K13/00 

FIELD: power engineering.

SUBSTANCE: method to intensify condensation of steam in a condenser of a steam turbine plant, consisting in the fact that during operation made of alternating modes of operation and routine works, on the steam turbine plant, in the mode of operation during steam supply from a steam generator, including a steam turbine, the shaft of which is connected with the generator, driven by the specified steam and generating moist steam, and a condenser. In the mode of routine works, steam supply from the steam generator is cut off, the turbine and the generator are shut down, hydraulic disconnection of the condenser from the turbine, the circulating pump, the system of return water supply is done. An external source of steam is connected, as well as a source of hot demineralised water and a system of return water supply, to the condenser. The plant for preparation of surfactant is connected, to which a surfactant source is connected, as well as a source of demineralised water and a source of steam. In the mode of routine works, a mono- or polymolecular film of octadecylamine is formed on the outer metal surface of the tubes.

EFFECT: invention makes it possible to increase efficiency of steam condensation and efficiency factor of a steam turbine plant due to provision of best conditions for steam condensation.
