Modification of heat exchanger for steam generation
Pačíska, Tomáš ; Jegla, Zdeněk (referee) ; Nekvasil, Richard (advisor)
This graduation thesis is concerned with a thermal exchange unit issue whereof one working substance complies with a two-phase mode of a flow. This unit is made for the steam generation. The thesis is supposed to solve operation problems causes of the given unit and to make a proposal of an appropriate solution that is supported by performed calculations. Part of the the work is strength calculation. This work also introduces the thermal-hydraulic processes issue of the steam generation equipment. There are also performed thermal-hydraulic control calculations in consideration of newly set-up operation parameters of the given equipment‘s working substances.
Complex strength design of condenser
Denk, Jakub ; Naď, Martin (referee) ; Lošák, Pavel (advisor)
This diploma thesis focuses on strength design of steam condenser. The goal of the thesis is to make strength calculations for the specific operation conditions, introduce possible solutions, provide recommendations and refer to weak points of such calculation procedures. First, thermal-hydraulic design in HTRI software is performed. Strength calculations respect ČSN EN 13445 standard. Strength calculation with imported temperature field is performed in ANSYS Workbench software. In the next step, another strength calculation is realized in Sant´ Ambrogio software. Results are evaluated in conclusion chapter, including recommendations for the possible following work.
Design of high-pressure heat exchanger
Marada, Petr ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
The aim of the thesis is to design a heat exchanger for heating natural gas in the mining process and subsequent treatment. The first part describes natural gas itself, its origin, mining and ways of treatment. There are described technologies used for finding the deposits itself or processes by which water, sulfur and solid particles are removed from the extracted gas. The next section deals with the types of heat exchangers most commonly used in industry. There are also described basic relations for heat-hydraulic calculation of heat exchanger. In the practical part the heat exchanger itself was designed. World-wide HTRI software was used for the heat-hydraulic calculation and for strength calculation according to the standard ČSN EN 13445 was used sofware Sant´ Ambrogio.
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.
The basic design of regenerative heat exchanger
Schütz, Stanislav ; Jegla, Zdeněk (referee) ; Kilkovský, Bohuslav (advisor)
Regenerative heat exchangers are established as a means of heat recovery in many industrial applications. The fixed-bed regenerators are mostly used to transfer heat from hot flue gas to cold air. In this work, several mathematical models of regenerators and several calculation methods were compared, while the preferred method is Willmott’s open method from 1964. Analysis of the influence of geometrical and operational parameters was carried out for the linear regenerator model.
