Determination of chlorine in fuels
Saitl, Pavel ; Köbölová, Klaudia (referee) ; Lisá, Hana (advisor)
This work presents and theoretically processes several standard methods for determining the chlorine content in biofuels. The advantages and disadvantages of each method are discussed, along with their comparison to one another. Additionally, the behaviour of chlorine during the combustion process, the impacts of gaseous chlorine on combustion devices, and possible mitigation strategies are described. Within the framework of describing the behaviour of chlorine during the combustion process, both high-temperature and low-temperature chlorine corrosion, which are most pronounced in boilers burning biomass-derived fuels and solid alternative fuels, are explained. The work also includes the natural cycle of chlorine, illustrating the negative impact that escaping gases from boilers burning biomass and solid alternative fuels have.

Heat-emission characteristics of the energy compost for small combustion plants
Bučinský, Václav ; Malaťák, Jan (advisor) ; Bradna, Jiří (referee)
The aim of this thesis is to get acquainted with the problems of biological and energetic use of compost. Emphasis is placed on the technology and features of the energy compost, which is intended for combustion, gasification or pyrolysis. The work presents characteristic properties and composition of solid biofuels. There are characterized pollutants, including hazardous properties. There are also mentioned legislative conditions, particularly in the area of emission limits and fuel quality in terms of air protection. Further, a description of the main design features of a small grate combustion plants.
The second part of the thesis contains a comprehensive analysis (elemental, stoichiometric, heat emission and economic) of selected samples of solid biofuels. Based on the analysis, the samples were evaluated and assessed whether they comply with emission standards and fuel quality requirements in terms of legislation. Analyzed fuels have been characterized and it has been proposed the use of appropriate energy for small combustion facilities.
