Abstrakt v cudzom jazykuThe Bachelor's thesis is focused on monitoring the properties of wood before and after it's thermal loading. The work is theoretical. The Bachelor's thesis contains a literature review of combustion theory. It describes the chemical and physical properties of wood, the structure of wood and their changes after heat loading of wood. The thermal load of wood changes the chemical composition. Hemicelluloses are the least thermally stable, the most stable is lignin. In the Bachelor's thesis are described changes of color wood, moisture and wood density, which were caused by thermal degradation of wood.
