Original Abstract

The present paper describes the options for reduction of harmful emissions from combustion of gaseous fuels with the main focus on the possibilities of nitrogen oxides (NOx) formation abatement in dependence on operation parameters, the kind of fuel fired and most importantly on the burner design. Measurements made in a large-scale experimental furnace were performed on the burner, with staged combustion fuel supply. Based on the data collected in the measurements was prepared an empirical model of NOx emissions formation. The core of the model is made up a of set of simplified kinetic equations of NOx formation using as independent variable a so-called equivalent temperature in the combustion chamber. By comparing the measurements results it has been found that the staging of fuel nozzles influences strongly the temperature in the combustion chamber and consequently also the emissions formation, mainly of nitrogen oxides. The model shows good agreement with the experimental data and respects the influence of the various parameters, e.g. of excess air and flame temperature. The model is expected to bring substantial savings in terms of number of validation experimental measurements with similar burner designs.
