초록

본 논문에서는 2중관 구조의 버너를 구성하여 난류화염을 완성하였다. 메탄-공기 예혼합 화염의 온도 및 농도장 측정에 비접촉식 흡수분광학 방식인 CT-TDLAS를 적용하여 연소생성물인 물 분자의 온도 및 농도장을 동시에 계측하였다. 고온측정의 정확성을 높이기 위해 단일 레이저 및 복수 레이저를 비교 평가하였다.

Abstract

In this paper, a double-tube structure burner was designed to achieve a turbulent flame. The CT-TDLAS, a non-contact absorption spectroscopy method, was utilized to measure the temperature and concentration field of methane-air premixed flames. Simultaneously, the temperature and concentration field of water molecules, as combustion products, were measured. To enhance the accuracy of high-temperature measurements, a comparison and evaluation were conducted between a single laser and multiple lasers.
