Abstract

This bachelor's thesis deals with the effect of two thermal approaches, torrefaction and roasting, which assess fuel parameters and the differences between them. Two types of pellets were chosen as fuel, where the input material was spruce and perennial hornbeam. The input materials were crushed, and the resulting sawdust was tested for particle size and distribution. Spruce and hornbeam sawdust were then pelletized. Tests were carried out on the obtained pellets, which revealed their properties. The individual performed tests are further described in this bachelor's thesis. After the tests, one part of the spruce pellets was torrefied and the other part roasted. The same experiments were also carried out with pellets from perennial ryegrass. After individual experiments, laboratory tests were carried out again. The conclusion of the work is a comparison of the results, a comparison of two thermal methods, their effect on the original biomass, and an assessment of the input materials.
