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.

Particle Polymer Composite in structural details of the building envelope
Dostálová, Darina ; Lavický, Miloš (referee) ; Vokoun,, David (referee) ; Matějka, Libor (advisor)
Due to a European energy concept for reducing energy consumption and also the concept of sustainable development, there is a growing demand for reduced energy consumption during the operation of the building and hence increasing demands on the thermal and mechanical properties of the building envelope. For this reason, it is necessary to look for materials that could meet both thermal and mechanical properties, as well as mechanical resistance and loadability, especially for the application for the foundations of the house, the base of the house and for application to structural details for elimination of the thermal bridges between interior and exterior boundaries. The main motivation for choosing the topic of thesis was to find materials derived from recycled or secondary raw materials that would be suitable for manufacturing composite applicable for structural details in the envelope of the building and for insulating in humid environment. An economic and environmental aspect plays an important role in the choice of material. The main theme of the thesis is the laboratory manufacturing of a composite with a thermoplastic matrix derived from recycled plastic materials and waste foam as a phase. Has been developed a unique Waste-based Particle Polymer Composite (WPPC) made from recycled foam and polypropylene. However, before WPPC can be reliably used by construction designers, physical properties of WPPC must be accurately identified. Therefore, it was designed laboratory manufacturing system and sample testing system, it was studied thermal, mechanical, thermomechanical and moisture absorptivity of WPPC. Application of finished composite material with satisfying thermal insulation properties to structural details to eliminate the thermal bridge, was the next step. These are details of the unloaded, prefabricated balconies, windows, atics, as well as basement constructions and the heel of the central load-bearing wall, the terrain flooring and the staircase wall
