A study on the thermal decomposition temperature (TDT) and critical ambient temperature (CAT) of cotton

Journal Article


Abstract


  • Cotton is a flammable material and some cottons

    would decompose or even self-ignite at bad storage

    and transport conditions. This paper studied the spontaneous

    combustion of cotton from the aspect of thermal

    decomposition temperature (TDT) and critical ambient

    temperature (CAT). From Fourier transform infrared

    spectroscopy analysis and chromatographic and mass

    spectrometric analysis, significant thermal decomposition

    was detected at the temperature of 210 ° C, which indicated

    that the TDT of cotton was around 210 ° C. From TG

    analysis and small-scale CAT test, activation energy of

    cotton and CAT of small cotton stack were obtained.

    Then, CATs of the cotton stacks with different dimensions

    were calculated based on Frank-Kamenetskii theory.

    With the dimensions l increased from 0.2 to 3.2 m, the

    CATs of cotton decreased from 195.0 to 137:9° C. The

    TDT of cotton was higher than these CATs, and the differences

    between TDT and CAT of cotton varied from

    almost 15–70 ° C (with the dimensions l increased from

    0.2 to 3.2 m). As the experiments and calculation of the

    CATs were very complicated and time-consuming, the

    CATs of cotton can be estimated if the TDT was known.

    The result of this paper was especially meaningful for

    evaluating the risk of spontaneous combustion of cotton

    and speculating the reason of cotton fire.
