| Popis: | An investigation of processes taking place in the upper part of open diffusion flames of acetylene with various diluents enabled the kinetics of carbon interaction with complete combustion products at 1800 to 2150 K to be studied. The reaction is of first order with respect to carbon dioxide within the temperature range 1800 to 1940 K. Water vapour has no appreciable effect on the reaction rate at these temperatures. The gasification rates follow the Arrhenius law and can be calculated using the formula W = 1 ⋅ 15 × 10 5 exp ( − 75000 RT ) × ρ c o 2 g c m − 2 sec − 1 Above 1940 K the reaction deviates from the first order, the gasification rates reaching their maxima between 1960° and 2030 K and diminishing with further increase of temperature. Increasing the concentration of water vapour, with temperature and partial pressure of carbon dioxide remaining constant, results in a reduction of the gasification rate at temperature above 2000 K. |
