15MW급 부분예혼합 초저 NOx 가스연소기에 관한 실험적 연구

Experimental Study on 15MW partially premixed Low NOx burner

In this study, combustion characteristics for 20t/h water tube boilers are studied. The burner by applying The fuel staging technology, the air staging technology, the partially premixed technology, the separated flame technology and the flame inner recirculation technology was designed. This study was to determine the combustion characteristics for the three types of burners. It is found that the result of flame temperature measurement is less than $1300^{\circ}C$ at the all flame region. also, emissions of NOx and CO are found to be 15.8 ppm and 18.9 ppm, respectively.
