Určení optimálních mechanických a fyzikálně-chemických vlastností paliv pro ZEVO.

Abstract

This work focuses on the uses of laboratory thermal analysis methods TGA/DTG (thermogravimetry analysis/derivative thermogravimetry) and DSC (differential scanning calorimetry) together with the identification of physical and chemical properties of fuels to optimize their properties and subsequent use in ZEVO (facility for energy recovery of waste). Among the goals of this work included assessment of qualitative requirements for fuel for ZEVO, development in the EU and research of thermal properties of components in terms of their optimal thermal use (combustion, pyrolysis, torrefaction). The thesis describes the introduction to the issue, the issue of zero waste, energy recovery of waste, theoretical evaluation of thermal analysis and their methods, thermochemical changes during thermal processes, which were followed by thermal analysis methods for various samples of waste biomass (spent coffee grounds, waste wood, tetrapak, compost, soot) and study of physical properties (particle size). In the conclusion, specific steps are described, the use of thermal methods in individual parts of the work, which have shown that a suitably selected chemical agent can significantly affect fuel behavior during thermal processes by increasing reactivity and thus shortening the decomposition time and reduce the desired decomposition temperature.
