Originální abstrakt

The aim of the present study was to experimentally investigate the performance of two oxygen-enhanced combustion (OEC) methods, namely the premix enrichment and air-oxy/fuel combustion. The OEC combustion tests were performed with the conventional experimental low-NOx type burner, namely the two-gas-staged burner. The overall oxygen concentration was varied from 21 % to 38 %. The combustion tests were carried out at the burner thermal input of 750 kW for two combustion regimes – one-staged and two-staged combustion. The oxygen concentration in the flue gas was maintained in the neighbourhood of 3 % vol. on dry basis. The aim of the tests was to assess the impact of the oxidant composition, OEC methods and gas-staging on the characteristic combustion parameters in detail. The parameters included the concentration of nitrogen oxides in the flue gas, flue gas temperature, heat flux to the combustion chamber wall and in-flame temperatures distribution in the horizontal symmetry plane of the combustion chamber.
