Analysis of proces fluid pretreatment for heat exchange purpose
Navrátil, Ondřej ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
This thesis is devoted purification of a gas stream with solid and liquid particles. The problem described in the thesis is connected with a real industrial case – problem of operated waste gas incineration plant. Waste gas going to thermal incineration to flame of natural gas combustion contains solid and liquid particles. Presence of particles causes fouling of waste gas preheater. The main objective of thesis is analysis of situation and operating and space limitations and design of a suitable type of particle collector to reliable elimination of particles from waste gas before entering the gas preheater and thus to mitigation of fouling of preheater heat transfer area.

Solving of off-gas cooling system for removing contained solvents
Blažek, Pavel ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
Diploma thesis deals with searching of the most appropriate solution of air mass cooling to clear away contained solvents. The solution is based on real and operated pharmaceutical unit. The cooling system is solved as systém of three tubular heat exchangers. In the first heat exchanger the air mass is cooled down by water, in the second by ice-cold water and brine R32 is used for cooling in the third heat exchanger. Heat exchanger system is solved for cooling the air mass which results in condensation of contained solvent – acetone.

Design of heat exchangers for high temperature applications
Jonák, Martin ; Kilkovský, Bohuslav (referee) ; Kermes, Vít (advisor)
This thesis is devoted to thermal-hydraulic design and rating of heat exchangers with the specialized commercial software HTRI. These heat exchangers are solved for real high-temperature applications, where the hot fluid is a flue gas with high temperature (above 500 °C). In the thesis is made a brief analysis of the conventional design of heat exchangers usable for high-temperature aplications, description of the basic relations, description and brief user manual of software HTRI. Further, work includes a comparative study of methods for calculation of pressure drop of the fluid at 180° elbows, as support analysis for solution of required applications characterized by low pressure drop of process fluids.

Hydrodynamic analysis of basic equipment in units for the thermal processing of wastes
Říha, Kamil ; Kilkovský, Bohuslav (referee) ; Pařízek, Tomáš (advisor)
Thermal processing of wastes is a metod, when during combustion occur reduction of wastes till 10% previous volume. The main advantage of this method is possibility to heat utilization for heat and electric production. Through thermic process develops range of pollutants (NOx, CO, SO2, HCl, HF, PCDD/F) that had to be remove from off-gas or reduced to enviromental values in agreement with laws in force [16]. For this purpose are combustion units equip with range of devices for removing this pollutans. The main task of this diploma thesis is selectoin of ctirical device in term of pressure drops. The value of pressure drop stands significant part in proposition of efficiecy off-gas fan. In increase or decrease total pressure drop consumption of electrical energy of off-gas fan is rising or going down. Change of consumption in total classification is projecting in energy utilization rate of waste where is determinate if it stands of energy utilizatoin or just incineration. In first part of diploma thesis are described in detail availability methods of off-gas cleaning where is described their principle, advanteges, disadvatages and comparison of effectivity. In second part of diploma thesis is made example model about influnce technology on value of total pressure drop. There were chosen two technologies for removing dioxins (technology of catalytic filtration REMEDIA and DeNox/DeDiox). For both technologies were made detailed analysis of pressure drops single components of these technologies. Attainment results were compared and rated with one another. For analysis these two methods were designed mathematical process in software Maple 9.5.

Processing and evaluation of experimental data measured at prototype unit for energetic utilization of biomass
Blažková, Blanka ; Kilkovský, Bohuslav (referee) ; Urban, Lukáš (advisor)
Main task of this final thesis is to analyse experimental measured data of prototype unit with output of 1 MW for energic biomass utilization. Furthermore the aim is to get acquainted with energic biomass problems utilization in middle output kettles and with stationary source legislation. To transfer measured value due to legislative conditions this diploma work solves the conversion procedure which is necessary to evaluate emission limits for measured concentration CO, SO2, NOX and stiff contaminating matters. My final work put emphasis on graphics processing in general tables and graphs with trends describtions. Endeavour is achieve discussion bilateral connection.

Calculation of heat loss and pipe insulation
Tuček, Jan ; Jegla, Zdeněk (referee) ; Kilkovský, Bohuslav (advisor)
In this bachelor thesis "Calculation of heat loss and pipe insulation" describes the mechanisms of heat transfer and listed equations for calculating the Nusselt number for heat transfer by convection. The following describes the types of thermal insulation properties and their uses. The last part of this thesis is devoted to the preparation of calculating the heat loss calculation of the required thickness of insulation according to the required temperature and the most economical insulation thickness calculations.
