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.

Model of district heating network
Kolenčíková, Jana ; Skála, Zdeněk (referee) ; Pospíšil, Jiří (advisor)
Subject of this thesis is district heating and heating network model design. Firstly, it de-scribes basic principles of heat supply and its elements. Secondly, computational model of heating network is created based on grid map of the network. The model contains proposed pipeline system and calculation of heat and pressure losses. Lastly, price map for heat con-sumption points, in dependence on heat losses, is presented.

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.

Mathematical modeling of district heating net
Pařízková, Iva ; Kracík, Petr (referee) ; Pospíšil, Jiří (advisor)
This thesis is focused on creating an iterative model for thermal and hydraulic calculation of heating net in Visual Basic of Application. Flowing medium considered is hot water. Although data for heating network in Brno are recorded in this model, its use for any other heating network is possible. This model allows also calculation of minimal temperature of the source and calculation of heat loss of every consumer. This is very useful when considering, if supplying some of the consumers with the heat from a local source would not be more effective. The second part of this text is aimed to evaluation of different ways how to reduce the heat loss in heat network for source Červený mlýn. Both current situation and possibilities for the future are considered.

Calculation methods for tube banks heat exchanger
Housírek, Jiří ; Jegla, Zdeněk (referee) ; Kilkovský, Bohuslav (advisor)
This diploma thesis deals with calculation methods of heat exchanger with cross-flow tube bundle. The first part of the thesis contains summary of generally known basic calculation relations used in calculations of heat exchangers and a detailed description of a given heat exchanger.The second part of the thesis provides a description of available calculation methods of a given aparatus required for its thermal and hydraulic calculation. The final part describes application POST in 1.0 which has been formed on the basis of these calculation methods. Using this application check calculation of exchanger with cross-flow tube bundle was carried out and gained figures compared with results gained by means of professional calculation program HTRI.

Heat exchanger design
Vítek, Tomáš ; Lisý, Martin (referee) ; Špiláček, Michal (advisor)
This bachelor thesis deals with the design of an additional flue gas exchanger for the use of residual energy of flue gas. Part of the work is a summary of the knowledge about heat exchangers, their principle, operation and maintenance. The next part of the thesis is the calculation draft of the heat exchanger, calculation of heat transfer and subsequent calculation of hydraulic losses for the designed exchanger. Part of the bachelor thesis is a drawing documentation of the designed exchanger too.
