Steam boiler with grate firing burning wheat straw
Křivák, Petr ; Kohout, Přemysl (referee) ; Lisý, Martin (advisor)
The aim of the thesis is the design of the steam grate boilers of 40 t/h for straw burning. The required parameters are generated steam temperature 420 ° C and a pressure of 5.5 MPa. The specified fuel is cereal straw with a calorific value of 9.5 MJ/kg. The calculation is made from the stoichiometric calculation of elemental analysis, to calculate the individual dimensions and heating surfaces of the boiler.

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.

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.

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.

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.
