초록
본 연구에서는 입자상물질 저감을 위해 개발한 디젤미립자 필터를 선박용 고속 디젤엔진에 적용하여 측정방법에따른 저감효율을 비교 분석하였다. 시험에 사용된 엔진은 최고출력 403 kW의 4행정 기계식 선박용 고속 디젤엔진이며, 선박 엔진의 부하와 회전속도 제어를 위해 AC 동력계를 사용하였다. 선박 엔진 시험주기인 E3 cycle의 네 운전조건에서저감효율을 측정하였으며, 측정방법으로는 입자상물질 및 soot의 저감특성을 살펴보기 위해 분류희석 방법과 광흡수법이적용된 계측기를 각각 이용하였다. 디젤미립자 필터 적용에 따른 저감효율 측정 결과, 엔진허용 배압을 충족함과 동시에입자상물질의 경우 76 ~ 91 %, soot(≈블랙카본)은 90 %이상 확인할 수 있었다. 이 결과로부터, 선박용 디젤엔진에서 배출되는 입자상물질 및 soot 저감기술로 디젤미립자 필터 적용 가능성을 확인할 수 있었다. 또한, 측정방법별 저감효율이상이한 결과로부터 측정방법의 단일화 필요성을 확인할 수 있었다.
Abstract
This study was conducted to compare the particulate removal efficiency of the developed diesel particulate filter using various measurement methods in a high-speed marine diesel engine. A four-stroke mechanical marine diesel engine is used for the test, which has a maximum output of 403 kW and is coupled to an AC dynamometer to control engine speed and load. The test was conducted based on four steady-state engine operating conditions of E3 engine test cycle for the measurement of PM and soot removal efficiency using partial dilution method considered as gravimetric method and filter smoke number method as light absorption method, respectively. As a result of the removal efficiency measurement according to the application of diesel particulate filter, particulate matter was reduced from 76% to 91% and the soot was reduced by more than 90% while meeting the permissible engine back pressure. From these results, the applicability of diesel particulate filter adopted in high-speed marine diesel engines could be confirmed. In addition, based on the result that the particulate removal efficiency varies with different measurement methods, the necessity of unification of these methods could be identified.
