SPECTROSCOPIC OBSERVATION ON THE COMBUSTION CHARACTERISTICS OF JAPANESE TRADITIONAL OIL LAMP
ABSTRACT: In this research,
spectroscopic measurement has been made
to investigate the combustion characteristics of a Japanese traditional oil
lamp, called toumyou, that has been used since ancient periods
until present. Combustion characteristics, i.e. flame stability and
temperature, were analyzed by using a temperature video camera. Spectral
emission intensity of hydroxyl (OH) radical (band head of 310 nm) was measured
by using a UV-visible spectrometer and visualized by a CCD camera while the
brightness was measured using a lux meter. The
experimental result showed that the flames of vegetable oils burned were
stable and temperatures ranged over about 1000-2500ºC. In addition, the emission
intensity of OH radical was successfully
detected by the UV-visible spectrometry and visualized by the CCD
Camera. The emission intensities of OH radical from flames of coconut oil and palm
oil were higher than those of other tested vegetable oils. From measurement
using a lux meter, it was obtained that coconut oil gives the brightest flame.
