RDF Grate Biomass Boiler
Kudýn, David ; Křemínský, Pavel (referee) ; Lisý, Martin (advisor)
The master’s thesis deals with the design of a grate boiler with natural circulation for the combustion of refuse-derived fuels with the required heat output of 5 MW. Stochiometric calculations are executed at the introduction of the thesis, furthermore, the efficiency of the boiler is set down by an indirect method. Afterwards, the dimensions of the boiler are designed, with individual heat-exchanging surfaces. The last part of the thesis is dedicated to verifications of heat balance, the check of chlorine corrosion and setting down pressure losses for working medium and also for flue gas. The scheme of the boiler is attached in the appendix.

Biomass and waste gasification and cogeneration by the help of microturbine
Kašpar, Matěj ; Najser,, Jan (referee) ; Baláš, Marek (advisor)
This diploma thesis investigate the question of combined production of heat and power by the gasification of biomass. The introduction describes basic dilemma energy conversion from biomass. Further, special attention at the gasification technology and it´s usage at combined heat and power production is paid. The main section includes schematic proposal cycle with use of microturbine 80 [kWe] as well as basic calculation, which serves as a base for folowing project optimization. For discussed optimization is made concept of configuration, thermal and aerodynamics calculation for both heat exchangers B1 and B2. Last but not least these heat exangers were compared by different aspects such as influence of deposits on power transfer and pressure loss. At the end of the work calculated numeric values are discussed and the project of heat exchanger with it´s advantages for practise are summarised.

The use of waste heat cogeneration units for steam and heating
Jež, Dalibor ; Skála, Zdeněk (referee) ; Baláš, Marek (advisor)
This master’s thesis deals with design of technological system for heating and process steam generation. The source of energy is a cogeneration unit. The thesis is divided into several parts. The first part is design of technological system and description. The second part is realized stoichiometric calculation and the thermal balance of steam boiler. The main part of thesis is design of the waste heat steam boiler. The thermal calculation, aerodynamic calculation, hydraulic calculation and strength calculation were made. The thesis also includes the drawing of designed waste heat steam boiler.

Aerodynamic Calculation of Air Part of Steam Boiler
Kudela, Libor ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
The aim of this thesis is to realize analysis of problematics of aerodynamic calculations of steam boilers on the part of combustion air. On the basis of project documentation realize evaluations of sectional dissipation factors of each component of inlet tract. Realize calculation of summary pressure (draft) loss. Specify components with highest loss and propose options of their optimization.
