Abstract

Water emulsion technology has the problem of unstable combustion due to the rapid separation of water. To solve the problem, a hybrid mixing device was developed. The device attached on the burner was tested. As a result, the fuel consumption reduced to 12% in the similar condition of exhaust emissions and flame temperature, and 45.5%, 98.5% and 97.2% of NOx, CO, and smoke were reduced at the same inlet air and fuel flow rate.

물혼합 에멀젼 기술은 물의 급속한 분리에 의하여 불안정한 연소를 나타낸다. 이러한 문제점을 해결하기 위하여 많은 연구가 진행되고 있는데, 본 연구에서는 연료펌프입구까지 혼합연료를 순환시킴으로써 물의 분리를 최소화하는 하이브리드형 혼합장치의 성능을 분석하였다. 원통형 실험용 보일러에 버너를 부착하였으며 연료와 물의 유량을 조절하고 흡기유량을 제어하면서 배기농도와 화염온도를 계측하였다. 실험결과 배기농도와 화염온도를 유사하게 유지하는 경우 연료 소모율이 12% 저감되었으며, 흡기 유량과 디젤유 유량을 동일하게 유지하는 경우 질소산화물이 45.5%, 일산화탄소가 98.5% 스모크가 97.2% 감소하였다.
