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 walkable bridges for wastewater treatment
Denk, Jakub ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
This thesis focuses on design of walkable bridges for wastewater treatment plant for the company Váhala a spol. s.r.o. In the first part, there is generally described process of wastewater and technologies, which are used for this treatment the most. In following chapter, there is performed design of walkable bridges, especially supporting frame. Part of the thesis concentrates on strength analysis of the most critical components of construction by finite element method. Static computing is performed according to valid European standards – Eurocode 3. Appendixes includes samples of basic technical drawings.

Search in the area of boiler and their design
Táfl, Josef ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
The aim of thesis is to create a division of boilers used in industry, especially boilers to generate heat and electricity, and describe the main parts of the boiler compiles in detail. Another task of this work is to build the basic procedure for a draft industrial boilers according to valid standards. These boilers are used for strength calculation, where the calculated pressure-resistant components and thermal calculation, in which are heat areas projectet.

Design of energetic unit pipeline
Adamec, Martin ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
This diploma work is aimed at a proposal and an overall controll of the pipeline net. There is a preliminary calculation performed (by the analytical method) in this diploma work. There is also a comparison with the numerical computing to find out whether the pipe branch does or does not comply.

CFD geometry optimalisation of heat exchanger
Stromský, Ondřej ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
The main task of thesis is to find optimum geometry of the heat exchanger. The biggest emphases is placed to finding the most optimum of streaming liquid in the heat exchanger and to minimisation pressure losses. There is a effort to regulate the streaming liquids in heat exchangers so that in multitube and on the shell side don´t create dead areas, it means to avoid sedimentation of particle in these places. Dead areas cause rising resistance against heat transfer and necessity of frequently cleaning the heat exchanger. For these reasons is necessary to do analyse of flowing and to looking for the optimal geometry of the 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.

Design modification of heatexchanger for steam generation
Prášek, Radovan ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
This thesis deals with heat exchangers. Thesis is divided into two parts. First one is devoted to various construction of equipment for heat exchange, basic divisions and overwiew of the types. The second part deals with a specific solution modification of existing equipment. The solution includes a description of the problematic parts, calculation of selected parts, design modifications and basic drawings of the proposed solution.

Design of equipment for steam generation and superheating
Jakeš, Martin ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
This thesis describes the design of a new circuit for the production of superheated steam instead of the original heat exchanger, which showed frequent failure. In the introduction is disassambling the problems of the existing heat exchanger and the proposed method of solving the problem. Proposed is a new process circuit consisting of a heat exchanger to heat the steam, separator and heat exchanger for superheated stream. Gradually, the work both heat exchangers are designed thermal and strenght. In the thermal part is modeled all process circuit and calculated in the program ChemCad. The strength calculation is solved analytically according to EN 13 445, then all dimensions of heat exchangers are optimized. In the conclusion is verified by metod of finite element critical part of the exchanger. After successful completion of the design thermal and strength calculation was made relevant drawing documentation.

Design of process unit pipeline
Butek, Petr ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
The master’s project deals with the pipeline systems of process unit. The design of the industrial pipeline is usually extensive and complex task interwoven with a lot of technical disciplines. Diploma thesis is focused on the strength calculation of the pipeline specified by the ČSN EN standard. The main goal of the calculation is appraisal of the most stressed parts under operating and testing conditions. The diploma thesis is handled with the key aspects that influence the overall concept of the pipeline design as well as the strength calculation.
