FIELD: power engineering.
SUBSTANCE: combustion chamber, particularly for gas turbine is made with at least one wall of combustion chamber through which cooling fluid medium flows and with two resonator facilities of different resonance frequency; resonator facilities are built-in into wall of combustion chamber so, that flow of cooling fluid medium passes through them. At least one of resonator facilities has such resonance frequency, that it operates as a high frequency resonator, while at least one of resonator facilities has resonator frequency for operation as a resonator of medium frequency. High frequency resonators and medium frequency resonators are connected parallel and serially.
EFFECT: reduced consumption of cooling air.
