Design of heatexchanger
Nováček, Filip ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
The aim of this bachelor thesis is to design a heat exchanger which will be part biogas cogeneration system. This work will be divided into two parts. The first part deals only with the known types of industrial heat exchangers, operation and maintenance. The work is not addressed the issue of transfer and exchange of heat because the thermal-hydraulic calculation was the subject of enter. In the second part is design solution heat exchanger according to given parameters controlling, the calculation of pressure parts of the heat exchanger according to ČSN EN 13445-3 and FEM calculation of the critical parts of a heat exchanger. The thesis is also the drawings forms of the heat exchanger.

Design of column
Marko, Libor ; Buzík, Jiří (referee) ; Nováček, Filip (advisor)
The thesis contains information about the design of pressure vessels and describes their individual parts. It is mentioned production of individual parts and the process including assembly parts in one unit. The thesis includes options of control and testing of pressure vessels. It is described kinds of built-ins of distillation column and the basic principles and types of distillation. It is created stress analysis of pressure vessels parts according to ČSN EN 13 445 – 3, and also stress analysis of the selected part of column by using FEM. Mechanical drawing of distillation column is part of the thesis.

Furnace design
Stříž, Michal ; Nejezchleb, Radek (referee) ; Nekvasil, Richard (advisor)
This master´s thesis deals with issues of tube furnaces in the process industries, especially with a design of a transfer pipeline, which is one of the main parts of the furnace. According to the requirements, designed pipeline is stress analyzed using the two pipeline programs Japar and Caesar II, that are briefly described. In addition to this design several variants of analysis are performed and the results are compared. Comparison helps to explain the diversity of the programs. For example, the effect of elbows on the stress analysis. The master´s thesis also describes the factors that affect the working life of the furnace.

Design of heat exchanger
Klučka, Ivan ; Nekvasil, Richard (referee) ; Lošák, Pavel (advisor)
This thesis is focused on the thermal-hydraulic and construction design of heat exchanger with floating head. The introductory part is dedicated to the design of heat exchangers. Next part is focused on the thermal-hydraulic design created in HTRI software (module Xist. The next section is the strength calculation of selected components of the heat exchanger according to EN 13445 in software Sant'Ambrogio. The following part describes each of the analysis in software Ansys Workbench. The final part contains complete manufacturing documentation of heat exchanger.

Design of distillation column
Matýs, Ondřej ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
Distillation columns play a very important role in petrochemical industry. The requirements to their safety and lifetime are being constantly stepped up. Hence, they have to be designed very carefully and special attention is to be paid to strength analyses. The diploma thesis is focused on strength analysis of the distillation column carried out according to the ASME Code, Section VIII. Parts of the equipment and some nozzles were analyzed in operational and test conditions. One particular nozzle was analyzed more thoroughly by means of FEM, stress categories were considered. The work also includes worked out drawing documentation.

Calculation of heatexchanger
Kvapil, Matěj ; Naď, Martin (referee) ; Klučka, Ivan (advisor)
This bachelor thesis focuses on strength calculation of a heat exchanger according to ČSN EN 13445. First stage is an introduction into the theme of heat exchangers and their calculation. Next part is about the calculation according to ČSN EN 13445 itself. Part of this thesis is also strength analysis of selected items using numerical method (FEM). Annexes include calculation in software Microsoft Excel and basic drawings of items.

Heat Exchanger
Čípek, Petr ; Pavlů, Jaroslav (referee) ; Fiedler, Jan (advisor)
Heat exchanger is a device mediating the exchange of heat between two flowing mediums. This exchange can be periodical or continuous. The choice of the type of heat exchanger depends on the usage and parameters of entering medium. This thesis deals with the tube recuperation (recovery) exchanger and calculation of new one. This new heat exchanger is supposed to replace current one produced by Kralovopolska in 1974. These heat exchangers have wide range of application. They are widely used in all fields, from energy related equipment to the pharmaceutical plants. The conversion of current heat exchanger was made according to the CSN EN 13 445 for non-heated pressure vessels. The calculation was made for all pressure load parts, among these are the mantle, beds, throats, tube plates and tube feet. All parts are suitable for all the styles of load.

Fatigue evaluation methods for pressure equipment utilising numerical analysis results
Boleloucký, Václav ; Lošák, Pavel (referee) ; Létal, Tomáš (advisor)
Diplomová práce se zabývá hodnocením únavové životnosti v okolí konstručního uzlu tlakové nádoby, kde vzniká výrazná koncentrace napětí a je zde předpoklad primárního vlivu na únavu materiálu. Konkrétně se jedná o místo přechodu kontrolního otvoru do pláště analyzovaného zařízení. Práce obsahuje teoretickou a praktickou část. V teoretické části jsou představeny pojmy a metody hodnocení, související s danou problematikou. Na základě těchto metod je provedena analýza konstrukčního uzlu tlakové nádoby. Analýza je provedena metodou konečných prvků na skořepinovém a objemovém modelu nádoby v softwaru ANSYS Workbench, její výsledky dále zpracovány a vyhodnoceny dle aktuálního návrhu úpravy evropské harmonizované normy EN 13445--3, kapitoly 18. Výsledky analýz jsou hodnoceny v závěru práce.
