Steam boiler for sorted waste burning 85t/h
Vítámvás, Zdeněk ; Baláš, Marek (referee) ; Skála, Zdeněk (advisor)
This thesis deals with a project of steam boiler to combustion of refused-derived fuel. With respect of required fuel and output parameters of the steam was worked out stoichiometry, energy loss and boiler efficiency, heat flows was allocate to individual heat exchange surfaces. The heat exchange surfaces was calculate and project in detail.

Design of Electric Steam Heater
Pekárek, Michal ; Šulák, Marek (referee) ; Lisý, Martin (advisor)
This master’s thesis is focused on the design of electric steam generator for superheated steam. Using heating cartridge is the easiest way how to make a saturated or superheated steam. This device is part of gasification reactor, which is used for experimental purposes. The thesis includes schematic involvement of technology. Technology contains evaporator and superheater. The evaporator is calculated as pool boiling. The superheater is design for steam flowing through heating cartridge bundle. At the end of the thesis are made projection drawings, which are based on the calculations.

Grate RDF Boiler
Krolák, Michal ; Křemínský, Pavel (referee) ; Lisý, Martin (advisor)
This master's thesis deals with design of steam grade boiler for burning refuse derived fuel with power output of 70 t/h. The assignment contain a requiered steam output parameters and composition of fuel. From this composition of fuel is calculated stoichiometric calculation, the heat loss and the efficiency of boiler. After that follows a design of the boiler with closer design of each of the heating surfaces.

Steam boiler for fytomass
Baláš, Jiří ; Ing. Obrovský (referee) ; Skála, Zdeněk (advisor)
The purpose of this Diploma Thesis was the construction design of the steam boiler for fytomass. For the specified parameters of biomass have been gradually implemented stoichiometric calculations of which are further based calculation of enthalpies of combustion gas. In the next part have been dealt with heat balance of the boiler, the efficiency of the boiler, recirculation of exhaust gases and the temperature of the combustion gases in outlet from fire. Thereinafter, the proposal of particular heat surfaces of steam boiler was solved, so that the resulting number and size correspond to the desired parameters. The parameters are temperature, pressure and the amount of steam.

Steam boiler burning wood 60t/h.
Dufek, Adam ; Baláš, Marek (referee) ; Skála, Zdeněk (advisor)
The aim of the work is to design a plain wood combustion boiler of 60 t/h output. Fuelling component analysis has been added to the basic boiler parameters. Stechiometric calculations were performed for given fuel composition. Thermal efficiency was set after making thermal balance. Separate convective areas and boiler proportions were designed together with separate steam output parameters (temperature, pressure, amount). Design documentation was added.

Draft boilers for co-firing natural gas and blast furnace gas
Šebela, Jakub ; Svoboda, Petr (referee) ; Baláš, Marek (advisor)
The aim of a diploma thesis is design of draft boiler for co-firing blast furnace gas and natural gas. In the first part is made the stoichiometric calculation for the gas mixture. Next is the proposal of combustion chamber and proposal of individual heating surfaces of boiler. Next part contains the thermal calculation and control of individual heating surfaces. Part of the work is also drawing documentation of boiler.

Gas heat pumps based on stroke engine
Bedřich, Miroslav ; Fiedler, Jan (referee) ; Pospíšil, Jiří (advisor)
The aim of this Diploma thesis is a description of gas heat pump (GHP) technology and the possibility of their usage in real life. Also units from the major manufactures of GHP units in the Czech Republic and abroad are evaluated from technical and economical point of view. The thesis as well includes a part where is decided if it is better to further develop GHP units with higher or lower performance. In the last part of thesis are cooling circuits designed for both lower and higher performance, than performance of existing GHP unit Polo 100. As a result, the units with higher performance are more perspective. Therefore heat plate exchangers, which serve as a condenser and an evaporator, are designed for unit with higher performance.

Design of industrial boiler with cogeneration
Mička, Radek ; Tvarůžek, Martin (referee) ; Křenek, Ladislav (advisor)
The diploma thesis deals with the design of the industrial boiler for biomass, Which deals with the issue of the energy future of combustion of fuels using current power generation - microcogeneration, designed for larger houses or smaller com- panies. The shape of the device is the interconnection of individual functional and technological parts of the boiler, a view of a new product that re ects its function. It uses modern and timeless materials, color and control technology to achieve overall comfort and time savings and service.

Modular absorption cycle
Honka, Pavel ; Pavlů, Jaroslav (referee) ; Pospíšil, Jiří (advisor)
The thesis is focused on the cooling cycles, namely cycles of absorption. The work is divided into several parts, as problems to be solved. The first part deals with the principles and using refrigeration cycles in practice, their involvement and by comparing the working pairs of substances circulating in the absorption unit. The practical part deals with making a proposal for one-and two-level modular absorption cycle of 6 kW, and the subsequent techno-economic comparison with commonly supplied absorption unit
