Biomass gasification model
Studený, Vojtěch ; Baláš, Marek (referee) ; Milčák, Pavel (advisor)
Mathematical models of gasification are suitable for predicting gas composition and its properties. The aim of the diploma thesis is to compile a mathematical model for biomass gasification. The first part deals with the description of gasification and the technologies used. Theoretical part consists of the search of modeling methods. Other theoretical part is devoted to the description of the model and equations presented in the thesis. Part of the assignment is a parametric study that shows changes in gas production and its properties when changing the parameters. Finally, the model is compared with the data obtained in the experiment on the fluid reactor biofluid 2.

Pyrolysis-Gasifying Unit
Hruška, Daniel ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
This diploma thesis deals with the problem of so-called two-stage gasification, which have the potential of producing gas-fuel with a very low tar value, which has a parameter of its quality evaluation is very important. The thesis deals with processes that are taking part in pyrolysis and gasification, further attention is focused on finding parameters and optimal conditions of operation in order to suggest the basic design of gasification unit. The actual design of the unit consists of a simplified energy and mass balance model and the design of its own partial and significant components. The work is supplemented by an experiment and its evaluation.

Atmosferic gasification of biomass by the addition of oxygen and steam
Vypušťáková, Veronika ; Milčák, Pavel (referee) ; Baláš, Marek (advisor)
The topic of master´s thesis is atmosferic gasification of biomass by the addition of oxygen and steam. The theoretical part is devoted to the description of biomass, process of gasification, kinds of gasification reactor and product gas. Further experiments are devised depending on the gasification medium and output temperature. In this case, the key aspect is the steam addition control. In the practical part, these experiments are performed in a fluidized bed reactor. Resulting values from samples of gas and tar are subsequently processed and evaluated.
