Title:
TEMPERATURE DISTRIBUTION MEASURING INSTRUMENT FOR INSIDE OF COMBUSTOR
Document Type and Number:
Japanese Patent JP3281857
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a temperature distribution measuring instrument for the inside of combustor with which the temperature distribution can be satisfactorily measured over a wide range in a combustor.
SOLUTION: The inside of a combustor 1 is irradiated with two laser beams 28, which are obtained by synchronizing the laser beams of two laser oscillators 11 and 12 while a little shifting the oscillation timing, through a measuring window 26, two kinds of fluorescent light are generated on the optical path of the laser beams 28, this fluorescent light is received through the measuring window 26, the fluorescent light intensity at every light reception time is detected while utilizing the difference of detection time proportional to the optical path length difference until two kinds of fluorescent light are separately generated and the fluorescent light reaches the measuring window 26, and the temperature distribution in the depth direction inside the combustor 1 with respect to the measuring window 26 is measured based on the fluorescent light intensity distribution at such a time.
