Properties and the Use of Metal Foams
Křivánek, Robin ; Liškutín, Petr (referee) ; Němec, Karel (advisor)
In this thesis are summarized the findings of metal foams, with prevailing constraints on aluminum foam, because in them hides the greatest potential. The first part is described the production of porous materials, especially the way of floam production by thermal decomposition of floaming agent and melt gas injection. There are also written stress tests to gain a deeper knowledge of their properties, but also the latest exploring methods of foams, such as using a radioscopiy and CT scanner from which then creates a voxel model of foam. They are summarized here the basic ways of processing. Finally we must mention the possibility of using these materials with a focus on commercially produced foams Alporas® and Duocel®. Mass using foams mainly prevents high production costs and in some cases difficult reproducibility of properties.

Steam boiler for natural gas
Křivánek, Robin ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
This diploma thesis describes the design of steam boiler for combustion natural gas, which has a steam power 80t/hour. In the first phase is performed calculation of stoichiometric amount of combustion air and flue gas. After that follows constructional proposal of the combustion chamber. Furthermore continue by calculation heating surfaces of the boiler. In conclusion, the thesis is focused on designing the injections. To check the accuracy of the results is recalculated heat balance the whole boiler.
