Hot-air balloon using and specification requirements review
Olšanová, Markéta ; Třetina, Karel (referee) ; Juračka, Jaroslav (advisor)
The bachelor thesis deals with the history of balloon flying worldwide and in the Czech countries and utilization of the hot-air balloon at present. Furthermore it provides a sur-vey of the biggest world balloon manufacturers, description of the structure and parts of hot air balloons including their types and suitability of their use. Finally, it includes a digest from the construction specifications CS-31 HB as well as the L series regulati-ons valid for operation, identification and registration marking of hot air balloons.

Cutting plasma beam
Tejkal, Roman ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
This work deals with general drifts in the sphere of plasma cutting and with technological possibilities of plasma ray with intention on individual parameters of plasma designations. Here is described temporary state and direction of development of consumer parts, burners and sources for plasma cutting. Detailed adumbration of direction of development is described in the peroration.

Characteristic parameters of combustion of low calorific fuels
Kvapil, Matěj ; Bělohradský, Petr (referee) ; Hudák, Igor (advisor)
The diploma thesis is focused on the combustion of the low calorific gaseous fuels. The first part is devoted to the characterization and usage of low calorific fuels. Then combustion theory focused mainly on emissions and thermodynamics. Next characterization of burners and their modifications for low calorific value fuels is described. Safe storage and handling of chosen gases is also included in the last chapter of the theoretical part. Practical part includes the description of the laboratory experiment, which was a part of this thesis. It consists of the experiment description, experimental plan, calculation and evaluation of emissions, high and low heating value, density, flame temperatures and heat flux. Laboratory experiment was carried out with different fuels. Low calorific fuels were simulated by gradual increase of the concentration of inert gasses in the natural gas. Increased concentration of inert gasses had positive effect on the emissions. Measurement of the flame temperatures confirmed that the decrease of emissions corresponds to the inert gas addition to the noble fuel. Heat flux and thermal efficiency of the combustion was almost identical for each configuration.
