Abstract—It is important to measure the internal
temperature or temperature distribution precisely in
combustion system to increase energy efficiency and reduce the
pollutants. Especially in case of large combustion systems such
as power plant boiler and reheating furnace of steel making
process, it is very difficult to measure those physical properties
in detail. Measurement and analysis by tunable diode laser
absorption spectroscopy can be attractive method to overcome
the difficulty. In this paper, TDLAS methods are used to
measure the oxygen concentration and temperature
distribution in various experimental conditions. Especially, this
paper suggest a possible approach to measuring an ununiform
distributed condition.
Index Terms—Tunable diode laser absorption spectroscopy,
temperature distribution, gas concentration, oxygen.
