Optimization Models in Energy Production
Němcová, Lucie ; Bednář, Josef (referee) ; Popela, Pavel (advisor)
This bachelor's thesis focuses on optimization of a boiler's size of a waste incineration plant from an economic point of view. The problem was approximated by discretization because random parameters with normal distribution occured in the incineration plant model. To evaluate the quality of such approximation there were created confidence intervals using random sample information, independent random number streams method and common random number streams method. Used methods were compared and the smallest number of scenarios that aproximates the problem "well enough" was proposed in the last part of this thesis.

Waste horizon
Ochotná, Barbora ; Rypl Žabčíková, Ada (referee) ; Kristek, Jan (advisor)
The city is a place of accumulation, production and reproduction of production resources and consumption of goods, but waste typically accumulates outside it. It falls out of our horizon physically and mentally. The waste we produce changes the landscape and transforms the processes on earth without most of us visiting the "places of transformation". The project works with the idea of redirecting the final phase of the production chain back to the place of consumption by producing elements of public space from municipal waste. The presentation of waste leads to an awareness of its amount and degree of consumption. At the same time, waste becomes something much more ambivalent, possibly useful or even beautiful.

Steam Turbine for Waste to Energy
Hodonský, Lukáš ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
The thesis deals with the design of the steam turbine for a waste incinerator. First, the concept and design of the machine is discussed. Following part is the steam turbine thermodynamics calculation, which is the main part of the thesis. My work also contains calculation of axial force and a simplified calculation of the gearbox. The design sections of individual modules and drawing of a disposition of a steam turbine are made on the based of the calculation.

Waste heat recovery vith steam turbine
Korytár, Zbyněk ; Vlček, Lukáš (referee) ; Fiedler, Jan (advisor)
The aim of this thesis is the design of municipal waste incinerator using the generated steam for power generation and distribution of heat. At the beginning is engaged in development of waste issues and the current state of waste management. The next section describes the options of waste treatment and possible solutions to the current state of waste issues. The concept of waste incineration plants: For waste incineration is used line for burning 100,000 tons of municipal waste per year.Combustion takes place in a grate boiler. Its advantage is the versatility and flexibility to waste. Electricity generation is dealt with condensing turbine with controlled consumption. The flue gas cleaning is designed to semi-wet method. The final stage involves the calculation of the balance, the calculation of electric energyand basic economic evaluation.

Modern methods of wet cleaning flue-gas
Kubíček, Jan ; Kermes, Vít (referee) ; Dvořák, Radek (advisor)
Research of conditions when sulphure dioxide is absorbed from flue gas, is the main objective of this master's thesis. Efficiency of this flue gas cleaning was measured on an experimental device, which consist of an absorption column filled with structured packing’s, and another component so-called "O-element". Further, a possibility of upgrade this "O-element" to tread more flue gas is presented.

Modern methods of wet cleaning flue-gas
Kubíček, Jan ; Grolig, Ondřej (referee) ; Dvořák, Radek (advisor)
The main theme of this master’s thesis is to acquaint with flue gas cleaning problems. Also modernization of experimental device called “O-element”, installed in laboratory at Institute of process and environmental engineering, is involved in this master’s thesis. “Oelement is used for cleaning acid elements from flue gas. Further there are results of experimental measuring on this device, and their estimation.

Recovery of Energy from Municipal Wastes
Šíma, Kamil ; Bébar, Ladislav (referee) ; Jícha, Jaroslav (advisor)
The topic of the diplome thesis is draft of the waste-to-energy plant for municipal waste with cogeneration of heat. Basic specification of project: Waste-to-Energy plant is facilitated by two rotary kilns of type operating in parallel. Further flue gas leaving the post-combustor enters a multicyclone unit to separate substatial portion of fly-ash. Heat of flue gas at the temperature of 1000°C generates superheated steam in a Heat Recovery Steam Generator (HRSG). Dry sorption process is appllied for flue gas treatment. Specifically sodium bi-carbonate is used for it. Products of reactions and remnants of dust are separated by a baghouse. Superheated steam, generated by two HRSG, presents the inlet stream of a condensing steam turbine with steam extraction. The diploma thesis contains calculation of major devices and basic economical and financial statement of project.
