Analysis on the Secondary Carbonization Experiment and the Rule of Temperature Field Evolvement of Coal Sample
The coal sample preparation is an important part for the study of coals character, and therefore, the man-made secondary carbonization method of coal sample preparation was explored in the text. Firstly, the scheme of secondary carbonization was designed, and then, according to it, the heat transmission and the temperature field evolvement rule were analyzed in the process of carbonization. Finally, the secondary carbonization experiment of coal sample preparation was conducted, and the coal sample was obtained successfully. The results show that the temperature rise velocity in the center of coal sample is from fast to slow in the process of secondary carbonization, and the reasonable calefaction time is about 15000 seconds.
