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.

Grate Boiler for Biomass and Coal Co-combustion
Baláži, Martin ; Ryšavý, Milan (referee) ; Skála, Zdeněk (advisor)
This thesis solves a design of a grate boiler burning wood chips or brown coal with a heat output of 160 MW. Stoichiometry flue gas is calculated according to the specified composition of each fuel. The dimensions of the individual heating surfaces are primarily calculated for burning wood chips and subsequently checked for the combustion of brown coal. Design of the boiler is completed by checking the overall heat output. Boiler design is accompanied by drawing documentation.

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.

Steam Grate Biomass Boiler
Suchánková, Lenka ; Křemínský, Pavel (referee) ; Lisý, Martin (advisor)
The master's thesis describes the design of the steam boiler, which burns biomass with heat output of 6 MW. The required parameters of the steam are a temperature of 300 °C and a pressure of 2,5 MPa. The thesis is gradually devoted to stoichiometric calculations through heat losses and boiler efficiency, to the design of the combustion chambre, heat exchangers and pressure losses. Part of the thesis is drawing documentation of the boiler.

Grate Boiler for Biomass Combustion
Szabó, Gergely ; Svoboda, Petr (referee) ; Svoboda, Petr (referee) ; Lisý, Martin (advisor)
The thesis deals with the design of a grate steam boiler which has natural circulation and is determined for combustion of wood chips. The boiler has a capacity of 45 t/h and produces superheated steam with the output parameters of 3,5 MPa and 450 °C at the 125 °C feed water temperature. Stoichiometric calculations and the flue gases enthalpy calculations are based on the composition of the specified fuel. The efficiency and fuel consumption of the boiler is also determined. The thesis mainly focuses on the thermal calculation and geometric design of the individual heat transfer surfaces of the boiler. The drawing documentation of the steam boiler is available in the attachment of the thesis.

Gas Boiler for Blast Furnace and Coke Gas Mixture Combustion
Dohnal, Jakub ; Svoboda, Petr (referee) ; Svoboda, Petr (referee) ; Lisý, Martin (advisor)
This diploma thesis deals with the constructional and calculation design of boiler for blast furnace and coke gas mixture combustion, including sizing of the heating surfaces. The opening section is dedicated to a brief characterization of burned fuels. The following chapter shows the parameters and composition of the resulting fuel mixture. The main part of this thesis involves; determining the stoichiometric amount air required for combustion and the resulting flue gas, determining the boiler efficiency and steam production rate, calculations regarding the combustion chamber and the detailed design of the individual heat exchangers. At the end of the thesis the heat balance of the entire boiler is verified. Drawing documentation of boiler is also part of this diploma thesis.
