Abstract: Broadband far ultraviolet (UV) emission (up to 200 nm) was recorded during combustion of heterogeneous systems with the formation of condensed reaction products. It was shown that UV emission occurred during combustion in various gases (He, Ar, and N$_2$) and had the highest intensity in helium at a pressure of 25 kPa. This emission is attributed to the chemiionization of gas, separation of charges in combustion products, and subsequent microbreakdowns.

Keywords: heterogeneous combustion, ultraviolet emission.
