Steam boiler for straw 10t/h, 320°C
Truhlář, Marek ; Kól, Přemysl (referee) ; Skála, Zdeněk (advisor)
The aim of this thesis is design a grate steam boiler for burning straw with an output of 10 tons of steam per hour. The produceds team has parameters 320 °C, 3,2 MPa. For a given fuel (fytomass) 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 steam and feed water temperature are designed individual convective surfaces and dimensions of the boiler. The boiler design includes drawings.

steam boiler for wood biomass 25t/h,5,5MPa, 475°C
Pecháček, Michal ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
The work deals with design of steam grate boiler with a output of 25 t/h, parameters of steam output p = 5.5 MPa, t = 475 °C and a temperature of feed water 105 °C. It is a boiler with natural water circulation by evaporation surfaces. Wood biomass is boiler fuel. The proposal consists of stoichiometric calculations, determination of boiler efficiency, thermal calculations and determinion geometric parameters of the boiler and its heat transfer surfaces. The boiler drawing is a part of the work.

Gasification of coal boiler 210 t/h; 13,63 MPa; 540 °C
Zajíc, Josef ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This thesis aims to gas installation of the coal boiler and its thermal recount. In the first part, there is implemented calculation of the combusting chamber. After that follows the recalculation of heat exchange surfaces and proposal tube air heater, which will replace the existing air heater Ljungström. The emphasis is placed on the preservation of the exsiting steam parametrs and keeps emission limit of NOx.

Thermal calculation of steam boiler
Růžička, Tomáš ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
The topic of this thesis is the thermal calculation of steam boiler with natural gas fuel. The first part is describing technical characteristic and parametres of the boiler. The main part of this thesis is the thermal calculation of the boiler. The following part deals with determination of steam amount and steam parametres for blowing through pipes of the boiler.

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 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.

Heat and electricity production in waste -to -energy plant
Szegedi, Peter ; Lisý, Martin (referee) ; Skála, Zdeněk (advisor)
This diploma thesis deals with a design of steam boiler used to incineration of mixed municipal waste. Based on the specified fuel and the required output parameters of the steam from a steam boiler is calculated stoichiometry of incineration, thermal losses and overall boiler efficiency. Other chapters of thesis are focused on construction and thermal calculation of boiler moves. Finally, this thesis is to check heat balance of the boiler.

Steam boiler for biomass and sand 92,5t/h
Špiláček, Michal ; Lisý, Martin (referee) ; Skála, Zdeněk (advisor)
This master’s thesis is dealing with design of steam boiler for wood chips. Wood chips are considered as biomass and so the steam boiler is considerate to enviroment. Main purpose of this work is calculation of size and number of water/steam heating surfaces so the boiler can produce steam with required parametres of temperature, pressure and amount.

Proposal dryers for biomass
Hrnčířová, Michaela ; Pospíšil, Jiří (referee) ; Baláš, Marek (advisor)
This thesis deals with reducing the moisture content of biomass drying and its subsequent use as biofuel. The work is a belt drying and its integration into the system with a grate boiler. It proposes a variety of drying options for use of different drying media. In the end, an economic evaluation of the combustion system uses a belt dryer, and a system without any possibility of drying the fuel before it enters the boiler.
