Heat balance of anaerobic part of sewage treatment plants
Řezáč, Jaroslav ; Beňo, Zdeněk (referee) ; Pěček, Jan (advisor)
This thesis is focused on anaerobic stabilisation of sewage produced by sewage treatment plant. Mesophilic stabilisation was chosen for the sewage treatment plant . In the first chapter, main attention is dedicated to general treatise on sewage treatment plant. Anaerobic process of stabilisation, digestion tank and some of the medium are characterised there. Next chapter is dealing with thermal balance for selected version of sewage stabilisation. A proposal of digestion tank and thermal insulation is also made there. Further, heat exchanger, boiler and combined heat and power unit are projected.

Airconditioning of surgeries
Znebejánek, Jiří ; Andrys, Petr (referee) ; Rubina, Aleš (advisor)
The subject of this bachelor thesis is the design of air-handling equipment of surgeries, consisting of three air-conditioning units. The equipment is designed to meet hygienic, operational and functional requirements for indoor cleanroom environments. Air handling equipment provides air exchange, heat loss coverage, heat gain removal, humidification and, in the case of one unit, dehumidification of the air. The theoretical part is focused on ways of regulation in air conditioning.

Steam turbine - condensation formation and discharge
Zouhar, Adam ; Filip, Patrik (referee) ; Fiedler, Jan (advisor)
Master thesis is dealing with the issue of condensate creation and removal from the Nesher Ramle steam turbine during start-up and steady state. At the beginning a preliminary calculation of heat balance and the turbine itself is done. It is followed by description and design of drainage system supplemented by calculation of the steam flow through the orifices. Steam flow calculation was done via S. D. Morris, Pavelek with Kalčík and Ambrož, all three methods were compared. The main goal is the theoretical calculation of the amount of condensate created during start-up which is influenced by its initial state from which it is started. Three default states are considered, cold, warm and hot. In the last chapter the comparison of theoretical calculation with the measured data on real turbine is done and it is supported by the evaluation of the data from the measurement of the steam turbine at steady state on maximum power and half power. From the steady state analysis, percentage of water flow to expander from the total amount of condensate formed in the turbine were obtained.

Calculation of the heat balance of latent heat utilization of flue gases by means of a condenser
Toman, Filip ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
Thesis is focused on calculation of the condenser of flue gas, which is created by burning of natural gas. In the first part is theoretical overview of equations describing film condensation and physical properties of the flue gas. The second part deals with practical thermal calculation of the specified condenser. In third part parametric study is done in which a tempature of cooling water at inlet and the coefficient of excess air are changed. The last part of the thesis is dedicated to geometric design of the flue gas condenser whose required power is 8 MW.

The savings in heating buildings
Rokůsek, Petr ; Hořínková, Lucie (referee) ; Počinková, Marcela (advisor)
This thesis theoretically in Part A deals with the solution in savings heating building and heating hot water. It examines the impact of austerity measures on the overall need for and consumption of heat energy and its economic impact and compared with each other in order to achieve maximum efficiency. Part B is their subsequent application to a given object - a residental building, various design alternatives and the resulting energy savings improvements. Experimental Part C deals with indirect measurement of the thermal conductivity of building materials.

Draft boilers for co-firing blast furnace gas and coke oven gas
Machara, Radek ; Křemínský, Pavel (referee) ; Baláš, Marek (advisor)
The diploma thesis deals with design of gas steam boiler with given parameters of steam. Blast furnace and coke oven gas are used as fuel. At the beginning of this work, both co-fired fuels are presented to us, their chemical analysis and stoichiometry are performed. The main part of the diploma thesis deals with the dimensioning of individual heat exchange surfaces such as steam superheaters, evaporators, economizers and air heaters. All heat exchange surfaces meet recommended parameters such as recommended steam rates, flue gas, etc. At the end, the total heat balance of the boiler is performed. Part of the work is also drawing documentation showing the main dimensions of the boiler. It is also indicated the connection of individual heat exchange surfaces.

Material properties research for use in high-temperature solar thermal storage tank
Šot, František ; Vala, Jiří (referee) ; TROJAN,, Karel (referee) ; Steuer,, Radek (referee) ; Šťastník, Stanislav (advisor)
The use of thermal storage energy, using phase change materials appears to be an effective way to store thermal energy storage with the benefits of the high amount of energy while maintaining isothermal nature of the process. PCM methods are used in latent thermal storage systems for heat pumps, as well as in solar engineering or for temperature control in spacecraft. The past decade has extended these principles for cooling and heating in the building. There are a number of PCM systems, which operate over a wide temperature range, are used in various applications. This document includes a brief overview of the development and analysis of available thermal storage working mainly on the principle of PCM.
