Use of the ESR method to study the combustion of gases at atmospheric pressure
- 14 Downloads
The possibility of direct measurements of the H concentration by the ESR method at atmospheric pressure in the combustion zone and in the combustion products of hydrogen-and hydrocarbon-air mixtures was demonstrated.
In the combustion zone of the mixtures studied, substantial concentrations of H atoms above the equilibrium values, reaching 1017 cm−3 for diffusion flames of hydrogen with air and 1016 cm−3 for methane-and propane-air flames, were detected in the combustion zone of the investigated mixtures.
