The demands for lowering the burdens on the environment will continue to grow steadily. It is important to monitor controlling factors in order to improve the efficiency of industrial systems and machinery such as engines, boilers and gas turbines. In particular, detailed measurement techniques for their parameters such as temperature and species concentrations are necessary to elucidate the overall nature of industrial systems. In Tokushima University the project named “Development of Industrial Applications on Laser Diagnostics (DIALD)” has been promoted for the purpose of elucidating the mechanisms and improving the efficiency of engines, boilers, gas turbines and so on. In this project, laser diagnostics such as computed tomography-tunable diode laser absorption spectroscopy (CT-TDLAS), laser-induced breakdown spectroscopy (LIBS), Raman spectroscopy and time-of-flight mass spectrometry (TOFMS) have been developed and applied to practical industrial fields. A consortium on CT-TDLAS including 11 institutes (2015 fiscal year) has also been organized and several joint researches have been performed toward practical applications. This report shows the research results of CT-TDLAS in the field of combustion analyses and applications to engines, boilers and gas turbines are discussed as a part of applications in the DIALD project
