FIELD: heat power engineering.
SUBSTANCE: invention is designed for location of air inflow places. According to proposed method, steam generated in boiler is directed to turbine, is condensed in condenser and main condensate of turbine is pumped through low-pressure heaters, and then main condensate of turbine is delivered by condensate pump into higher pressure deaerator and places of air inflow are determined by readings of oxygen meter. To locate these places multichannel oxygen meter is used by means of which oxygen content in main condensate after second low-pressure heater in direction of main condensate flow and in condensate after condensate pump of system heaters are measured and places of air inflows are determined by absolute values of readings of two pickups of multichannel oxygen meter and by difference inn said readings.
EFFECT: increased economy and improved reliability of thermal power station.
