METHOD OF CONTROLLING AIR-TIGHTNESS OF VACUUM SYSTEMS OF TURBO-INSTALLATIONS Russian patent published in 2016 - IPC F01K17/02 

FIELD: energy.

SUBSTANCE: invention relates to heat engineering. Method of controlling hermeticity of vacuum systems of turbo-installations through which at points of steam flow of excess pressure is determined visually looseness vacuum system, then steam medium-pressure cylinder extraction turbine plant and connected to this cylinder system water heaters and regenerative heaters of low pressure steam is excess pressure, which is fed into cylinder, for example, through heating extraction steam line, when the shaft-turning device of turbine plant, when completely closed turning control diaphragm at closed shutoff valves on steam extractions to feed water deaerator and heaters of high pressure and at open shutoff valves on steam extractions to network heaters and regenerative heaters of low pressure.

EFFECT: higher reliability of thermal power plants by increasing quality of detection areas of air suction in the vacuum system of turbine plant.
