Pvc and polietilentereftalat in the processes of combustion with substandard coal

Abstract For particles of binders – gas chlorvinyl is characterized by the consolidation of particles into a solid polymer phase with a slight increase in temperature due to adhesion and the formation of larger aggregates – polymer coagulants, which is accompanied by physicochemical and thermal processes such as adsorption, adhesion, coagulation and the formation of new phases. Thus, the interfacial interaction between the surface of the coal and gaseous vinyl chloride results in the contact of condensed matter of different nature, and the adhesion of PVC in the presence of coal particles provides between the particles of the briquettes the connection of a certain strength through physical or chemical molecular forces. To produce durable briquettes were also used supplements polyethylene terephthalate improves the calorific value and energetic properties of the resulting briquettes. Experiments with different concentrations of polyethylene terephthalate showed that with increasing concentration of this binder, the calorific value of briquettes is increased linearly.
