Abstract :

[en] Laser-induced breakdown spectroscopy was used to analyze unburned carbon in fly ash. The samples were gotten using fast ashing method and excited by pulse laser and plasma was formed at atmospheric pressure. The emitted signal which contains the information of unburned carbon in fly ash was detected. The calibration curve constructed base on six samples of one kind of coal ash, and two samples of other two kinds of coal ash were analyzed. The experimental results show that calibration curve constructed with the data from same kind of coal ash can be used to analyze the different kinds of fly ash using proper data processing method. The relative standard deviation of repetition of measured values are less than 8.08%, the relative errors are less than 2.27%. It is indicated that laser-induced breakdown spectroscopy is suitable for rapidly detect unburned carbon in fly ash with receptible applicability.
