Modern technological elements for tubular heat exchangers
Plánková, Tereza ; Babička Fialová, Dominika (referee) ; Jegla, Zdeněk (advisor)
The aim of this diploma thesis is to get acquainted with modern technological elements currently used in shell-and-tube heat exchanger in the shell-side and tube-side, thermal-hydraulic calculation of selected elements and comparison of thermal-hydraulic properties with classically used competing technological elements. The work deals mainly with EM baffle in the tube-side and tube inserts like the twisted tape type (and its modifications) and coiled wire in the tube-side. The theoretical part is focused on acquaintance with classical technological elements in shell-and-tube heat exchanger and with basic thermal-hydraulic calculations, practical part then on acquaintance with modern elements and thermal-hydraulic calculation of selected elements. These calculations are then compared with the results of the thermo-hydraulic calculation of similar elements.

Circular economy using analysis of separated municipal waste
Plánková, Tereza ; Kropáč, Jiří (referee) ; Nevrlý, Vlastimír (advisor)
The bachelor thesis analyses the current state of waste management and presents legislation and changes in waste treatment. The ban on landfilling of usable waste from 2024 and the set recycling targets are the main reasons for analysing the production of the separated components. The thesis deals with revealing potential for increasing the material, or energy, recovery of waste. As a key waste stream, biodegradable waste has been identified due to its rapidly growing production for the future. Modelling of production dependence for territorial units was performed using statistical methods in STATISTICA software based on socio-economic factors. The resulting model for production determination was obtained by multidimensional regression analysis. Applying the model to individual waste producers will allow efficient planning of support assets from an economic and infrastructure point of view.
