Abstract: Using a passive probe to record the accumulation of electrical noise signals of hydrogen-air flames, it is established that within the concentration limits of intense combustion of these mixtures, which are approximately 18–60% (vol.) hydrogen and are due to the interaction mechanism in the burning mixtures, there is a considerable increase in the degree of flame ionization.

Keywords: hydrogen-air mixture, combustion, chain-thermal explosion, flame ionization.
