Heating of Family House by Biomass
Vaculík, Jaroslav ; Štelcl, Otakar (referee) ; Lisý, Martin (advisor)
Bachelor´s thesis deals with the topic of biomass, its usage and potential and follow up the problem of heating a family house. The text contains introduction and outlines the biomass as an alternative of heating the house. Then it discusses its forms and devices designed for its combustion. The work also offers design and calculation of heating solutions for a model house on a particular object.

Advanced Stochastic Programming Models in Power Engineering
Pavelka, Ondřej ; Štětina, Josef (referee) ; Popela, Pavel (advisor)
This diploma thesis applies stochastic optimization in the field of the power engineering. In the thesis first part, the needed mathematical theory is described, specifically mathematical, linear, nonlinear, integer and stochastic programming. The second part deals with the heating plant, in which heat is generated by gas and biomass boilers. The aim of this thesis is to design a model for the schedule planning of these boilers. The model is based on two stage stochastic programming with scenario approach. Then the model is solved by GAMS software. In the final part of the text, the focus is on the model sensitivity analysis and suggestions for future improvement.

Design of an extraction steam condensing turbine in the Precheza company.
Pavelka, Tomáš ; Paseka, Bohumil (referee) ; Bok, Jaromír (advisor)
This diploma thesis is concerned with the design of the machinery with an extraction steam condensing turbine in Precheza corp. The theoretical part of this thesis describes the energetical situation in the company and the primary consideration about recovery of the heat, released at sulphuric acid production, for electrical power production. There is also presented brief description of the sulphuric acid production and the fundamental principles of the steam production at this process. In the practical part of this thesis there is performed the calculation of the heat-flow diagram of the steam turbine and the calculation of heat and producted electrical power at the basic operational states. There is presented the source code for the calculation of the heat-flow diagram using Matlab software. In the end there is mentioned the economical evaluation of the whole project, using the fundamental economical methods, such as net present value method, or profitability index, including the calculation of the pay-back period.
