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.
Jednotka pro odpařování precursoru pro PE CVD aparaturu
MACKŮ, Jana
The aim of the BS thesis is the design and construction of an electrically heated unit for controlled evaporation of precursor for PECVD apparatus. The work contains a description of the design of the evaporation unit and its implementation. The experimental measurements were performed with a PECVD apparatus. Thus, the designation of the characteristics of the evaporation unit was done to enable the utilisation of the project in laboratories. Furthermore, there is a comparison with the characteristics of a commercially available thermostatically heated evaporation unit enclosed.
