Energy utilization of sewage sludge
Poláková, Annamária ; Ferdan, Tomáš (referee) ; Frýba, Lukáš (advisor)
This bachelor’s work discusses the origin and composition of the sludge. The composition of sludge is given by legislation, as well as its treatment and processing. Sludge shall be adjusted in order to be used on agricultural land, landfilled, incinerated, etc. The sludge processes are described further in this work. Sludge disposal options are varied, but not everywhere equally represented. This is represented in chapter where treatment of sludge in Czech Republic and abroad are compared, illustrated in chats. The most extensive and most common method of disposal of sludge is application on the ground and burning. Usable energy is obtained by burning the sludge.

Co-incineration sewage sludge in the existing plant
Krejčí, Tomáš ; Ferdan, Tomáš (referee) ; Frýba, Lukáš (advisor)
This thesis focuses on problems with co-incineration of sewage sludge in existing plants. The introduction of my thesis deals with a brief summary of a sludge management, sludge treatment methods and subsequent utilizations methods used for sledge disposal. Next chapter contains a calculation of calorific value, depending on the water content and volatile substances in dry solids of the sludge, it offers an overview of devices applicable for thermal processing of sludge and a description of the co-incineration in existing plants. The seventh chapter is devoted to the legislative parameters which influence the ways of dealing with sewage sludge. After the thermal treatment of sludge it is necessary to decontaminate flue gases of harmful substances resulting from incineration process, thus following there is a description of the most important devices used for its elimination or its reduction. My work ends with a search of methods dealing with the thermal sludge utilization in foreign countries.

Flue gas cleaning in units for thermal processing of biomass
Ferdan, Tomáš ; Dvořák, Radek (referee) ; Kropáč, Jiří (advisor)
The master’s thesis deals with thermal treatment of biomass and with reduction of emission, which originate during this process. First part speaks commonly about biomass incineration and about technologies for emission reduction, especially cyclones. Practical part of this paper involves description of multicyclone evaluation by different authors and the comparison on of the evaluation on a case study of concrete multicyclone.

Effective Utilization of Municipal Solid Waste in Heat and Power Systems
Ferdan, Tomáš ; Bébar, Ladislav (referee) ; Ucekaj, Vladimír (referee) ; Stehlík, Petr (advisor)
This work focuses on effective utilization of municipal solid waste in heat and power systems. The effectivity in this work is evaluated from an economic as well as an environmental viewpoint. In the introductory part a review of legislation and state-of-the art in the fields of energetics and waste management of European Union is presented. Next an optimization tool NERUDA, created on the author’s workplace, is introduced. NERUDA consists of basic modules on which creation has the author been participating. The thesis is divided into two main parts that describe two NERUDA’s modules. First deals with a techno-economic model of waste-to-energy plants and is called Flexi model. The main output is a dependency of gate fee on capacity. Second part is devoted to the implementation of new module into the NERUDA system. This module is an environmental criterion for evaluation of the effectivity of waste utilization in the waste management and energetics.

Effective management of biological waste
Petříčková, Alena ; Ferdan, Tomáš (referee) ; Gregor, Jiří (advisor)
Theoretical part of present study gives a comprehensive overview of the methods used for the disposal of biodegradable waste with emphasis placed on highly effective techniques. Composting process is studied in detail and machinery used is thoroughly described. Acquired information from extensive research was applied to create a model of composting plant. Operation manual for this specific model forms part of the study. Afterwards various decomposing scenarios are analyzed and their economic sustainability is evaluated.

Evaluation of cogeneration units in Waste-to-Energy plants
Chýlek, Martin ; Putna, Ondřej (referee) ; Ferdan, Tomáš (advisor)
The purpose of this bachelor thesis is familiarization with legislation of evaluating combined heat and power generation systems and discover it´s questionable spots. Another objective is to make universal model of incineration plant and to apply calculation mentioned in legislation on various options of technology. The end of thesis is devoted to analysis of results.

Waste-to-Energy and effective energy utilization
Kadleček, Vít ; Ferdan, Tomáš (referee) ; Touš, Michal (advisor)
The diploma thesis deals with an increasing of utilization of energy during a combustion of waste. The introductory part deals with a presentation of the specific waste to energy unit and its combined heat and power production. In the next part is described a computing tool and the principle of its function. The main part od the thesis deals with a description of cumputing tool testing and with a summary of achieved results.

Models and approaches in the field of computer simulation of processes
Čech, Michal ; Ferdan, Tomáš (referee) ; Touš, Michal (advisor)
The diploma thesis deals with computer simulation of processes in the field of energy utilization of waste and biomass. The first part contains description of energy utilization from waste and biomass and fundamental devices of energy systems. There is also described methodology of modeling and techniques used for processes simulation. The next part is focused on mathematical models explanation of processes with constant and variable efficiency. In practical work are compared results from individual considered mathematical models with real data which were obtained from the real operation of waste energy plant. With use of gained mathematical models is considered model situation of cogeneration in the device of biomass and coal co-firing. At the end of this work is suggested implementation of created mathematical models into simulation program W2E.

Waste incineration in states adjacent to Czech republic and the potential of international waste market
Kadleček, Vít ; Frýba, Lukáš (referee) ; Ferdan, Tomáš (advisor)
This bachelor thesis deals with mapping of current and planned waste incineration plants in states bordering with the Czech Republic, and with the potential of international waste market. The introduction of the thesis describes the history and function of the waste incineration plants. The first main part, the legislation, defines waste incineration as energetic usage of waste, placing waste incineration to waste management and legislative conditions for realization of transportation across borders. The second main part informs about current and planned foreign waste incineration plants, which are located near to borders of the Czech Republic, because of formation of competition for planned projects in the Czech Republic.
