Tubesheet analysis according standards and FEM
Horniak, Patrik ; Vincour, Dušan (referee) ; Pernica, Marek (advisor)
The focus of this master’s thesis is strength design of tube sheet, which is part of shell and tube heat exchanger, with fixed tube sheets. This tube sheet is integrated with both shell and channel of the heat exchanger. First part of the thesis is focused on literature review of shell and tube heat exchangers, tube sheets and calculation standards, which are used for their strength design. The strength design of tube sheet is presented in second part of the thesis, according to the standards: ČSN EN 13445, ASME BPVC VIII and TEMA, along with comparison of these standards. Last section of the thesis deals with the implementation of FEM analysis and its comparison to the analytic approach of strength design, used in accordance to the standards mentioned above.

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.

Tightness evaluation of gasketed tubesheet
Trubač, Daniel ; Pernica, Marek (referee) ; Létal, Tomáš (advisor)
This master thesis focuses on the issue of tightness evaluation of gasketed tubesheet in U tube exchangers, which meets strength requirements of ČSN EN 13 445-3 and ČSN EN 1591-1 standards. It deals with the forces acting on the gasket when measuring the effects acting on the entire heat exchanger. A separate part is devoted to the calculation of the heat profile in the heat exchanger and verification of the strength of the heat exchanger. The final part introduces model of a heat exchanger, on which a possible approach to solving the tightness of the tubesheet in heat exchangers is presented. In thesis temperature field evaluation was conducted, the results of which were used in stress strain analysis, in order to obtain gasket contact pressure. Extreme gasket contact pressures were used to estimate leak rate limits.

Design of a kieselguhr filter body with vertical filter elements
Daněk, Jiří ; Marek, Tomáš (referee) ; Knoflíček, Radek (advisor)
The main goal of this diploma thesis is to design a filter body FKS 600 with vertical filter elements for beer filtration. The first part of the thesis deals with the current state of the market, evaluates the various types of filtration and their manufacturers, including its development and historical perspective. The following part uses the system approach for filter body design. The practical part of this diploma thesis is devoted to the design of the filter body FKS 600, this design is based on calculations of the pressure vessel. Assembly drawings and selected production drawings are processed for the filter body, which are annotated. The last part presents block diagrams and cost estimates for the production of prototypes or series, everything ends with a conclusion and summary for practice.

Technology expanding pipes into tube sheet
Podstata, Jan ; Císařová, Michaela (referee) ; Štroner, Marek (advisor)
The project developed within the Bachelor's degree program in Engineering Technology presents literary research in the field of tubing expanding in the tubing. There have been known several possibilities how to roll the tube from the history as well as new modern ways. The work includes an analysis of the types of joints and their characteristics. The openings in the tube and the ends on the tube must be adjusted and of particular tolerance. There are also several types of tools that can be used to roll the tube. The tool is chosen according to the type and the position of the joint.

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.

Strength calculation of heat exchanger tubesheet with focusing on economic evaluation
Horniak, Patrik ; Vincour, Dušan (referee) ; Buzík, Jiří (advisor)
This bachelor thesis is focused on strength design of assigned shell-and-tube heat exchanger. This heat exchanger have fixed tube sheets and straight tubes. Designed tube sheet is integrated with shell and flanged to the channel. First part of the thesis serves as introduction on the issue of heat exchangers and tube sheets. Following chapters are dedicated to the strength design of tube sheet thickness based on the ČSN EN 13 445 standard. These chapters are dealing with input parameters, basic requirements of calculation, equations essential for calculation of stress in heat exchanger and analysis of stresses in heat exchanger with the use of proper strength conditions. Conclusion of these chapters is evaluation of calculated results from personal scipt written in Python language using Spyder environment. Correctness of these results is ensured by their comparison with the output of Visual Vessel Design (VVD) program. Final part of the thesis is economic evaluation of whole tube sheet design based on possibility of choosing different analyzed material.
