Abstract

In order to optimize the combustion condition of the combustion system, it is important to know the information of the physical properties which vary during combustion. Gas concentration and temperature are the major target properties but it is difficult to measure exactly at combustion system. In this paper, a distributed feedback diode laser which wavelength is tunable in accordance with a function generator's output wave is applied to realize the laser absorption spectroscopy measurement. A concentration measuring test for 99% CO₂ gas was performed as basic experiment and major experiments were conducted on separation of interfered absorption signals at CO₂ and CO mixed condition.
