What is Pyrolysis Products from Different Biomasses: Application to the Thermal Cracking of Tar about?
09 Combustion (burners, combustion systems) the TGA under air, and then switching the gas flow to nitrogen and allowing the sample to further devolatilize until 1000°C. Also, partly burnt and/or pyrolysed samples were obtained from the TGA and characterized by optical microscopy techniques. It was observed that the volatile yields of all the coals were substantially reduced as a consequence of their initial heating under air. Besides, evidences of melting and thermal annealing in the inner core of burning coal particles were noticed to occur at lower temperatures than in pyrolysing particles. This was attributed to a sealing effect of the oxidation rim formed in the early stages of combustion, which might give rise to higher pressure build-up in the inner part of burning particles, thus enhancing the likelihood for condensation reactions to take place in the newly formed metaplast. As combustion profiles are commonly used to infer about combustion behaviour of coals, much care should be exercised in interpreting them, since even in a pure vitrain, two rather than one single material will be involved in the measured weight losses, and, more, these materials will often display fairly
