Hotwater boiler for natural gas,60 MW, 1,6 MPa, 150/70°C
Gardavský, Jan ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
The aim of this thesis is design a hotwater boiler for burning natural gas with an output of 60 MW. Boiler works with temperature difference 150 °C / 70 °C. For a given fuel is calculated stoichiometric calculation. The following is the calculation of the heat balance of the boiler including the determinativ of thermal efficiency. The fuel used, the required parameters of hot water and feed water temperature are designed individual convective surfaces and dimensions of the boiler. The boiler design includes drawings.

Stean boiler for sub bituminous coal, steam parametres 235 t/h, 14 MPa, 540°C
Horák, Stanislav ; Moskalík, Jiří (referee) ; Baláš, Marek (advisor)
The aim of the work is to design a brown coal combustion boiler of 235 t/h output. The work is divided into several parts. First, stechiometric calculations and calculations enthalpy of air and flue gas are performed. It is calculated heat balance of the boiler, the boiler losses and the thermal efficiency of the boiler is determined. After designing the combustion chamber thermal calculation is made. Then, individual heating surfaces are proposed and at the end of the calculations are controlling the overall energy balance of the boiler. For calculation was design documentation added.

steam boiler for woody biomass 88t/h
Lučko, Martin ; Ing.Milan Ryšavý (referee) ; Skála, Zdeněk (advisor)
The aim of the work is to design a plain wood combustion boiler of 88 t/h output. Fuelling component analysis has been added to the basic boiler parameters. For given fuel is prepared stechiometric calculations. After making the heat balance of boiler is determined the thermal efficiency. For given output of steam parametrs (temparature, pressure, volume) are designed individual convective surfaces and dimensons of the boiler. It is also made drawings.

Steam boiler with grate firing , burning coal or wood biomas 200 t/ h, 9,3 MPa 520°C
Čech, Jaroslav ; Hudeček, Mirko (referee) ; Skála, Zdeněk (advisor)
The aim of the work is the design of a grate boiler of 200 t . h-1 output, which will burn brown coal or wood chips. The work is divided into several parts. First, stoichiometric calculation and the calculations enthalpy of flue gases and air are performed. After calculating the heat balance and loss of the boiler was counted boiler efficiency. The design of individual heating surfaces is proposed and at the end are controlled the overall heat balance of the boiler. The calculation is supplemented by drawings.

Boiler for Brown Coal Combustion
Pavlo, Matej ; Hoffman, Pavel (referee) ; Skála, Zdeněk (advisor)
The aim of the master’s thesis is thermal calculation and dimensional design of boiler of 235 t/h which burns brown coal. The work is divided into several parts. In the first part, stoichiometric calculation and the calculations enthalpy of flue gases and air are performed. After calculating the heat balance and loss of the boiler, the boiler efficiency is counted. In the next part, thermal calculation of combustion chamber is calculated. Subsequently, design of the individual heating surfaces is proposed. Finally, the overall heat balance of the boiler is inspected. The calculation is supplemented by drawing of the boiler.

Steam boiler for wood burning 40t/h
Mach, Ondřej ; Křemínský, pavel (referee) ; Skála, Zdeněk (advisor)
The purpose of this Diploma Thesis is the construction design of the steam-boiler for the combustion of biomass – wood pellets. For the specified parameters have been defined stoichiometric calculations and calculations enthalpy burnt gas. In sequence, there is designed and solved the configuraion of the steam-boiler, so that the result design and the number of the heat-delivery surfaces can be determined, in dependence on the required inlet parametres of the air and outlet parametresof the water vapour. These parametres mean the amount, the temparature and the pressure. The aim of the thesis is to make a design of the steam.boiler burning biomass according to the set parametres. This very ecological fuel can really substitute the fossil fuel and friendly respect the environment.

Design of Steam Boiler
Kadlec, Tomáš ; Nechvátal, Ondřej (referee) ; Skála, Zdeněk (advisor)
This thesis is focused on design of black coal combustion boiler of 160t/h output. It consists of several parts. First, stechiometric calculations and enthalpy of air and gas are made, then heat balance of boiler and the boiler losses are calculated, and also thermal efficiency is determined. In next step, the combustion chamber is designed and its thermal calculation is made. Then, each of heating surfaces are designed, and in the last step overall energy balance of the boiler is checked. The scheme of pressure system and design documentation added.

Analysis of flue gas in automatic domestic boilers for agropelet
Minář, Marek ; Lisý, Martin (referee) ; Jecha, David (advisor)
The objective of the presented bachelor thesis is flue gas analysis during combustion of agropellets in automatic household boilers. Emphasis is placed on the description of biomass as a fuel, the ways of using biomass for energy purposes, alterations of biomass, production and properties of alternative pellets, automatic boilers and burners for combustion of specific fuel types. The end of the theoretical part is focused on standards and regulations for boiler operation. The practical part verifies the formation of emission on small sources of pollution and determines the concentration of solid and gaseous pollutants. The end of the practical part pursues with comparison of results with legislative requirements and calculation of boiler efficiency.
