Effects of hydrogen addition to natural gas on steam boiler operating parameters
Kocman, Lukáš ; Skála, Zdeněk (referee) ; Baláš, Marek (advisor)
This work deals with the influence of hydrogen addition to natural gas on the parameters of steam boiler operation. In the first part of the work, a steam boiler for natural gas is designed, which is then recalculated for natural gas with a volume concentration of hydrogen in the range of 5–50 %. Calculations for individual concentrations were performed in the Mathcad program and were placed in the appendices. Finally, the results are summarized and commented.

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.

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.

Design of steam gas boiler
Kuriál, Jakub ; Bursa, Robert (referee) ; Skála, Zdeněk (advisor)
This thesis deals with a design of a steam boiler combusting natural gas. It consists of stoichiometric calculation, determination of boiler efficiency, thermal calculations and determining geometric parameters of the boiler and its heat transfer surfaces. The results are verified by the heat balance of the boiler.

Utilization of biomass for micro cogeneration
Daňhel, Aleš ; Šejvl, Radovan (referee) ; Baxant, Petr (advisor)
This master’s thesis deals with utilization of biomass for micro cogeneration. The theoretical part of the master’s thesis defines main terms of the master’s thesis, which is biomass and cogeneration. The practical part of the master’s thesis is focused on the design and manufacturing of small micro cogeneration unit based on a small membrane steam engine. It means design of two steam generators to produce steam for the membrane steam engine. It will be also carried out design and production of membrane steam engine which is fitted with a small BLDC generator including electrical part for power output and measuring parameters. It will be made several measurements with the steam engine including measuring power output characteristic of the steam engine and measuring loading characteristics of the generator.

Steam boiler burning wood 60t/h.
Dufek, Adam ; Baláš, Marek (referee) ; Skála, Zdeněk (advisor)
The aim of the work is to design a plain wood combustion boiler of 60 t/h output. Fuelling component analysis has been added to the basic boiler parameters. Stechiometric calculations were performed for given fuel composition. Thermal efficiency was set after making thermal balance. Separate convective areas and boiler proportions were designed together with separate steam output parameters (temperature, pressure, amount). Design documentation was added.
