Abstract

This study modified the fuel hole design of an EV(EnVironmental) burner for hydrogen co-firing and evaluated its combustion performance and NOx emissions. The original EV burner showed increased fuel jet penetration and poor mixing under hydrogen co-firing conditions, leading to higher NOx emissions. To address this, the fuel hole diameter was increased by approximately 1.125 times. Experimental results showed that the modified EV burner improved NOx emissions as the hydrogen co-firing ratio increased and stabilized the flame front near the burner exit, enhancing fuel-air mixing. Combustion dynamics analysis confirmed stable combustion at higher flame temperatures.
