The use of ionization sensors for the study and diagnosis of the combustion process in gas-turbine power plants is substantiated in the paper. The review of literature data and in-house research show that thermionic emission of electrons from incandescent carbon particles plays a decisive role in the mechanism of ionization of flame sprayed in a stream of liquid hydrocarbon fuels.
