A model for the devolatilisation of large thermoplastic particles under co-firing conditions

Experiments and modeling of single plastic particle conversion in suspension

“…The thermal conductivity of polyethylene reported in the literature lies in the range of 0.18-0.4 W.m −1 .K −1 for temperatures below 220 • C. In some studies, it is assumed that the thermal conductivity decreases as the temperature increases or the thermal conductivity of the solid state material is higher than the liquid state [1][2][3][4]. However, for some cases, the thermal conductivity is considered to be constant [5][6][7] or increase with the temperature [8].…”

“…The specific heat capacity of polyethylene is mostly considered to be higher when the material is in the liquid state than in the solid state. The reported values are in the range of 1.6-2.6 kJ.kg −1 .K −1 for the solid state and 2.2-3.8 kJ.kg −1 .K −1 for the liquid state PE up to 400 • C [5][6][7][9][10][11][12].…”

The interrelationships between microstructure and melting, crystallization and thermal degradation behaviors of fractionated ethylene/1-butene copolymer

“…10. Figure 10a and b, respectively, illustrates the TGA and DTG curves of beginning steps of degradation, involving radical chain scissions [58][59][60], at the temperatures ranging from about 220 °C to about 450 °C, known here as "degradation initiation stage". In degradation initiation stage, dissimilar behaviors are observed for different P-TREF fractions.…”

Aerodynamic and Physical Characterization of Refuse Derived Fuel

“…RDF particles used in the cement industry are usually larger in size and highly scattered in shape compared to traditional pulverized fossil fuels. The effect of size and shape of single biomass , and plastic particles on the combustion time is studied in the literature. It takes a longer time for larger-sized RDF particles to combust in the calciner and the rotary kiln compared to the conventional pulverized fossil fuels.…”
