Optical assessment of ash melting behavior of solid fuels

Popis výsledku v původním jazyce

Ash fusion characteristics of solid fuels are key practical information for co-firing options and further thermochemical conversion processes. The study investigated the optical assessment techniques currently available for ash fusibility analysis, initially developed for characterization of coal ashes, later modified suit-able for solid biofuels. Though the standardized procedures are quite similar, but the difference between the common used guidelines were significantly identified with ash conditioning temperatures of 815 ±10°C and 550 ±10°C, respectively. The setting up for ash determination regarding to the shapes of specimens, ash prep-aration, test sample binding, particle size, and constant heating rates were reviewed. Several variations of definition on characteristic temperatures according to available standard methods for solid fuels were dis-cussed. The initial deformation temperature (DT) was highlighted as an indicative parameter in ash melting determination for main fuel and supplemental biofuels in co-firing options. Further examinations concerning ash contents, transformations of elemental compositions, morphological structural changes are essential for better understanding practical phenomena occurs
