Abstract

This study presents the performance test results and the analyses of the vitiated air heater with high temperature and high pressure. In the performance test, four test conditions and three rake measurement conditions were implemented. In the results of the performance test, the vitiated air heater met targets of temperature and flow rate, and the performance with maximum temperature of 2000 K and maximum combustion pressure of 40 bar was confirmed. Flow rate of provided methane increased 36% more than what was calculated, and 19.6% difference was displayed between measured temperature and theoretically calculated temperature.

본 연구는 설계된 고온 고압 연소식 공기가열기의 성능을 확인하기 위한 성능시험과 그 결과분석에 대한 것이다. 총 4가지의 시험조건에 대한 시험과 3가지 조건에 대한 레이크 측정 시험이 수행되었다. 성능시험결과 목표 온도와 공급 유량조건을 모두 만족하였으며, 최대 공급온도 2000 K, 최대 연소압력 40 bar의 조건을 만족하였다. 공급된 메탄의 유량은 이론값보다 최대 36% 증가하였으며, 측정된 온도는 이론적으로 계산된 온도보다 최대 19.6%의 차이를 보였다.
