The profiles of blends samples comprise a number of peaks
and vary depending on the characteristics of the content ofwaste
tyre. The curve of each blend lies between the curves of the reference
materials, and the contributions of waste tyre and coal
to these profiles can be clearly appreciated. Thus, the 10 wt.%
blends behave similarly to coal although showing some differences,
such as the practical disappearance of the chemisorption
stage and fixed coal combustion. It is also indicated from Fig. 1
and Table 1 that the maximum weight loss rate of the blends are
higher than that of the pure coal, and the corresponding temperature
and time decrease after waste tyre blended with coal.
Also, for the 10, 30 and 50 wt.% blends, the peak weight loss rate
decrease with the increase of waste tyre in the blends, it is indicated
that combustion processes of the blends are more complex,
which could be mainly attributed to the interaction combustion
between waste tyre and high ash coal, so when waste tyre is used
to replace partially coal, the appropriate content must be optimized
according to the physical and combustion performance
of waste tyre and coal.
