Abstract

In this paper, kinetic calculation of kuchekinsky coal plasma-air and plasma-steam gasification in a cylindrical channels with plasma source is performed. For kinetic calculations one-dimensional kinetic code Plasma-Coal were applied. Calculation results showed that gas phase in plasma-air gasification products, starting from the coordinate value of 0.15 m, is mainly represented by synthesis gas, concentration of which at reactor outlet is 48.6%. At the same time, the concentration of carbon monoxide over the entire temperature range is higher than the concentration of hydrogen. Their concentration at reactor outlet is 31.2% and 17.5%, respectively. Gas phase of plasma-steam gasification products is also represented mainly by synthesis gas. At 0.15 m reactor length, synthesis gas concentration is 93.9%, and reached up to 100% at reactor outlet.
