Sažetak
Implementation of stringent regulations of NOx emission requires the development of technologies for NOx removal from exhaust gases. In the introduction of this article the formation and the influence of NOx on environment and human health as well as the current state of NOx abatement strategy are summarized. The implementation of one among the so-called primary methods of the decrease of the NOx emissions was analysed on the test combustion facility regarding its reduction effectiveness in the course of combustion process. The propane-butane is used as a gaseous fuel. Standard industrial partially premixed gas burner applied very often in industrial metallurgical furnaces is considered as a candidate for implementing strategies for control of the pollutant emissions. As a method of temperature decrease in the combustion zone the external recirculation of flue gases was applied varying the excess air, the quantity of recycled flue gases and the thermal load. The recirculation of combustion gases was shown as the most effective method resulting in a reduction of the NOx emissions by up to 64%.
