Reduction of 137Cs Emission into the Atmosphere on Combustion of a Radionuclide-Contaminated Solid Fuel Under Conditions Involving Excitation of Thermoacoustic Self-Oscillations and Gas-Dynamical Pulsations

The emission of radioactive 137 Cs with fl ue gases in various regimes of combustion of radionuclide-contaminated solid fuels in a wide temperature interval has been investigated. The fl ame temperature decreased on the onset of vibrating combustion. A lowering in the 137 Cs emission under condition...

Beschreibung
Zusammenfassung:	The emission of radioactive 137 Cs with fl ue gases in various regimes of combustion of radionuclide-contaminated solid fuels in a wide temperature interval has been investigated. The fl ame temperature decreased on the onset of vibrating combustion. A lowering in the 137 Cs emission under conditions of vibrating and intermittent combustion in comparison with the emission under conditions of diffusion combustion has been obtained.
