Changing the fuel base of the coal boiler
Kallas, Miloš ; Burša, Robert (referee) ; Baláš, Marek (advisor)
This thesis deals with the change of the fuel base of a coal boiler due to the reduction of CO2 emissions and its thermal recalculation. In the first part, there is implemented calculation of the combusting chamber. This is followed by the recalculation of the heat transfer surfaces. The emphasis is placed on the preservation of the exsiting steam parametrs.
Gas Boiler - 220 t/h
Flodr, Jan ; Ryšavý, Milan (referee) ; Skála, Zdeněk (advisor)
For set parameters of a steam and a boiler feed water is designed a thermal and dimensional plan of the boiler, allowing high efficient requests. A boiler is used for combustion of blast furnace gas contains 10% of a natural gas used as a stabilisation element.
Steam Boiler
Skoupý, Jan ; Kól, Přemysl (referee) ; Skála, Zdeněk (advisor)
This thesis is focused on the design of steam boiler like a supplement for cogeneration unit of biogas plant. The main idea is to use a waste heat from the exhaust gasses to produce a technological steam of required parameters. The thesis contains of a calculation an amount of the heat in exhaust gasses and a heat exchange surface. An Aerodynamic loss and a wall thickness of the boilers are verified by strength calculation in the next parts of this thesis. At the end of this thesis are made projection drawings and diagram, which are made of the calculations.
Heating of the administrative part of the production hall
Pečenka, Matěj ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
The bachelor thesis deals with the design of the heating system, cooling of office and public spaces and the preparation of hot water by means of a cascade of air / water heat pumps. The first part of the thesis briefly deals with the history, function and distribution of individual types of heat pumps with a focus on the air / water heat pump. The second part contains a complete calculation and design of individual elements and equipment of the entire heating system. The last part of the thesis is a project at the level of construction documentation containing technical report and drawing documentation.
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.
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.
Design of steam boiler with grate firing burning RDF
Basov, Mykhailo ; Křemínský, Pavel (referee) ; Baláš, Marek (advisor)
This thesis deals with a project of steam boiler to combustion of refused-derived fuel. Considering the required fuel and output parameters of the steam was made the thermal calculation of boiler with it design and an individual calculation of heat exchange surfaces; hydrodynamic and aerodynamic calculations of the steam boiler.
Grate Boiler for Coal and Bagasse Combustion - 200 t/h, 9.3 MPa, 520 °C
Bartůněk, David ; Ryšavý, Milan (referee) ; Skála, Zdeněk (advisor)
The object of the thesis is to design a grate boiler for bagasse and brown coal combustion with a heat output of 160 MW. Calculations of a flue gas stoichiometry are based on known element analyses of each fuel. The crucial part of the thesis includes designs of heat-exchanging surfaces, where the bagasse is considered as the main fuel while the brown coal is the spare one. Overall thermal balance and an actual boiler efficiencies are provided in last chapters. The boiler-outlet flue gas temperature is compared with the dew point temperature at the very end of the thesis. As a part of the thesis there is a design of the boiler attached.
Grate Biomass Boiler - 88 t/h; 9.6 MPa; 520 °C
Střecha, Josef ; Hudeček, Mirko (referee) ; Lisý, Martin (advisor)
This master's thesis deals with the design of stoker-fired boiler for combustion of biomass. The main points of work are stoichiometry calculation of combustion, determining the dew point of flue gas, calculation of losses, which ones serves for determination of boiler efficiency, dimension design and detail calculation of thermosetting surfaces. In the last chapter is numbered total balance and real thermal efficiency of boiler.
The membrane wall of the boiler with an advanced flow control
Češla, Martin ; Tomáš, Zdeněk (referee) ; Tomáš,, Zdeněk (referee) ; Ing.Tomáš Zdeněk (referee) ; Pospíšil, Jiří (advisor)
The master thesis deals with hydraulic characteristics of once-through boilers and describes the problems which may arise during the flow of water through the evaporator. Especially the formation of aperiodic instability of the evaporator and hydraulic uniformity amongst every steam generating tube. The thesis describes parameters, which cause these problems, and solutions how to deal with them. The calculation has been done for evaporator of the boiler called K2 located in power station in Chvaletice.
