Original abstract
The aim of the present study was to investigate the performance of two oxygen-enhanced combustion methods, namely the premix enrichment and the air-oxy/fuel combustion. The observed combustion parameters included the concentration of nitrogen oxides in flue gas, the heat flux distribution lengthwise the combustion chamber and the flame pattern. It was observed that NOx emission is significantly lower when the air-oxy/fuel method is used compared to the premix enrichment method. Higher oxygen concentrations resulted in higher heating intensity.
Czech abstract
Cílem práce bylo experimentálně vyšetřit vliv dvou metod spalování s obohaceným spalovacím vzduchem, konkrétně metody "premix enrichment" a metody "air-oxy/fuel", na tvorbu oxidů dusíku (NOx), teplotu spalin, rozložení tepelného toku po délce spalovací komory a tvar a stabilitu plamene. Během experimentů bylo pozorováno, že NOx je výrazně nižší při využití metody "air-oxy/fuel" v porovnání s metodou "premix enrichment". Vyšší koncentrace kyslíku měly za následek vyšší tepelnou účinnost.
