The structures of three laminar premixed stoichiometric flames at low pressure (6.7 kPa): a pure methane flame, a pure ethanol flame and a methane flame doped by 30% of ethanol, have been investigated and compared. The results consist of concentration profiles of methane, ethanol, O, Ar, CO, CO, HO, H, CH, CH, CH, CH, CH, -CH, -CH, CHO, CHHCO, measured as a function of the height above the burner by probe sampling followed by on-line gas chromatography analyses. Flame temperature profiles have been also obtained using a PtRh (6%)-PtRh (30%) type B thermocouple. The similarities and differences between the three flames were analyzed. The results show that, in these three flames, the concentration of the C intermediates is much larger than that of the C species. In general, mole fraction of all intermediate species in the pure ethanol flame is the largest, followed by the doped flame, and finally the pure methane flame.

This paper presents the results of computational and experimental studies of the electroplasma gasification of carbon-containing technogenic wastes to obtain high-calorific-value syngas (H + CO) for power-generating devices. The composition of the syngas produced by gasification of organic wastes was experimentally determined. The change in the composition and calorific value of the syngas depending on the gasification time of organic materials was studied. The change in the calorific value of the syngas during waste gasification is considered.
