FIELD: energy.
SUBSTANCE: description is given of methods and devices intended for control of infiltration of ambient air, for example, in plant with organic Rankine cycle and exfiltration of process gas therefrom. To prevent exfiltration of process gas when plant with organic Rankine cycle is in operating mode, first sealing mechanism, such as dual dry gas seal, can be used. To prevent infiltration of ambient air when said plant is in stop mode, a second sealing mechanism, such as a stationary annular inflatable seal, can be used. In a plant with an organic Rankine cycle may be installed one or more pressure sensors for detecting, for example, occurrence of air infiltration and need for cleaning said plant.
EFFECT: high efficiency of power plant.
