FIELD: mechanic, energetic.
SUBSTANCE: the invention relates to the area of the heat power industry and can be used on thermal power plants. The thermal power plant contains a steam turbine, one of which, as a minimum, has a condenser, and a pipeline for steam feeding to the condenser of the turbine is connected to the pipeline of steam bled from one of the adjacent turbines. The monitoring of airtightness of vacuum systems of turbine plants is carried out by steam leakages through condenser leaking locations, by increasing the pressure in the condenser to an overpressure using the steam of regenerative turbine bleed. The proposed allows to increase the reliability of the thermal power plant by increasing the quality of detecting and elimination of locations of air inflow into the vacuum system of a turbine plant.
EFFECT: increases reliability of thermal power plant.
