Heating historic building alternative fuels
Lampa, Jan ; Ing. Vrána (referee) ; Vališ, Ivan (advisor)
The introduction of theoretical part deals with issue of fuel. There are basic kinds of fuels, their properties and calorific values. In next part a summary of types of boilers depending on the kind of fuel is described. A process of burning in each type is discussed. Then the basic issue of heat transmission, heat losses and design of individual elements of central heating system is described. In the second part there are two studies compared to each other. In the first one an automatic pellet boiler is used as a source of energy and in the second one it’s a heat pump, type air-water. At the end both of the variants are reviewed and the better option is chosen. In the last part the better option is designed, into detailed design documentation. Important design values for using the heating system and hot water service are calculated.

Static Solution of Water Pipes in Trenchless Technology
Mráčková, Martina ; Kytýr, Jiří (referee) ; Gratza, Roman (advisor)
The paper provides an overview of the most widely used trenchless technologies and the possibility of their utilization for laying new thermoplastic pipelines. It analyzes the static behavior of thermoplastic water pipes placed into the existing steel pipes using relining technology. The program system ANSYS is used as a tool for static solution of pipelines. Obtained results are compared with conventional approaches.

Chimneys draft and connecting fuel appliances
Kupka, Filip ; Formánek,, Marián (referee) ; Počinková, Marcela (advisor)
Diploma thesis deals with problematics of offtake of flue gasses. In experimental part there was measured compound of flue gasses by analyzator of flue gates. Aplication is a project of heating of object of The Academy of Sciences of the Czech Republic in Brno. Project solves design of heating system, flue and of source of heat. Heating area is created by floor convectors,towel rails and radiators. Source of heat is designed in two variants : as a cascade of condensation boilers and as a cascade of low-temperature boilers.

The design of fountains system
Müller, Patrik ; Štigler, Jaroslav (referee) ; Haluza, Miloslav (advisor)
The goal of this thesis is to design the fountain system. Nozzles have to squirt to the same height. Flow has to be the same on each nozzle and it has to be done for our given dimensionsThe right pump has to be chosen, but it cannot be done without proper knowledge of theroy of hydrodynamic resistence, basic hydromechanics and characteristics of the valves.

Production and assembly of a tubing for coal mill
Fešar, Tomáš ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis is focused on description of contract and all technicalities included in works supervision. First parts presents specification of design drawings which is necessary for price offer, next part describes design representing machining by means of repairs of wrongly drilled holes in steel structure of coal mill. Final part is dedicated to continuing to construction works and repairs of minor failing.

Pipe materials
Pecl, Tomáš ; Helcelet, Marek (referee) ; Molliková, Eva (advisor)
Objective of the bachelor thesis is to introduce the important aspects of the material for the manufacture, installation and operation of pipeline systems. The thesis mentions the suitability of individual groups of pipe materials for various technological and natural conditions with respect to the material properties. The work deals with the pipe installation, implementation of control tests with a focus on of technology pipe installation before commissioning, finding defects and the possibility of repair. Finally, in the work are placed practical information that helping solve problems

Heating of the Residential Building
Molnár, Lukáš ; Topič, Jan (referee) ; Vendlová, Lucie (advisor)
The goal of the work is to design heating and hot water production in an apartment block. Condensing gas boilers were designed for a heating system and a hot water storage tank, boilers should be located in a technical room in basement. Plate and tubular heating units are the heating surfaces. Heat consumption measurements in flats are gauged by remotely monitored calorimeters. The temperature in each flat is controlled by an electrically powered zone valve.

Heating of the residential building
Kašpar, Radek ; Horák, Petr (referee) ; Počinková, Marcela (advisor)
The subject of this bachelor's thesis is solution for heating and warm water preparation. The project contains more option of heat source for residential building. The first option source of heat is a gas condensing boiler. In the second option, the object is heated by a pellet boiler and hot water portion will cover the solar system. The theoretical part is a description of renewable energy use in residential building.
