Abstract
The dependences of the characteristics of filtration combustion of a mixture of carbon particles (10%) and an inert material on the oxygen content (5-50%) in a filtered gas are experimentally studied. The oxygen concentration in the injected gas is varied at a constant total gas flow rate in the first series of experiments and at a constant oxygen flow rate in the second series. It was found that, in both cases, the combustion wave structure changes along with the oxygen concentration. The temperature increases monotonically with the oxygen concentration at a constant total gas flow rate and passes through a maximum value at a constant oxygen flow rate. The maximum yield of carbon monoxide in both series of experiments is reached in the region of thermal wave structure inversion.
