Abstract

In this research, the influence of the nitrogen concentration in the oxidizer, oxygen/fuel equivalence ratio and temperature of the combustion chamber on the combustion characteristics of a natural gas fired oxy-fuel jet burner was observed. The thermal input of the fuel was 600 kW and the nitrogen concentration in the oxidizer was varied between 0 and 15 vol.-%, wherein either the maximum combustion chamber temperature or the thermal output were held constant.
