Biomass use in district heating
Dlouhá, Kristýna ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with the utilization of biomass in district heating. The introductory part of the thesis is dedicated to biomass, its division and ways of its utilization for energy purposes. The following section describes in more detail each of the technologies for power generation from biomass. In the third part, a few of our energy cogeneration sources are stated, they use previously mentioned technologies. At the end of the thesis there is a statistical overview of the utilization of biomass in district heating in the Czech Republic over the last 10 years.

Biomass Heating Power Plant Brno-nord
Saňka, Marek ; Skála, Zdeněk (referee) ; Fiedler, Jan (advisor)
The master’s thesis topic is the feasibility study of new biomass source construction in power heating plant Brno-North. The first part is focused on historical and current conditions and future development of heat distributions networks and sources of Brno. The power heating plant operation Brno-North is described in more detail including the current heat scheme of operation and plan for the future development. Next chapters are focused on projection of new biomass source. At first, it is defined heat output, operation range and parameters of the new source based on the data of real needs after the heating network modernization. Afterward, selected conceptual variants of the new source are discussed in more detail and for each of the variants are performed heat balance calculation and assembled heat scheme of operation. At the same time it is processed warehouse management calculation and economic analysis of the project. The final chapter evaluates the technical and economic parameters of variants and recommends the most suitable variant of the project.

District heating systems in the Czech Republic in the context of legislative changes
Hylas, Martin ; Poul, David (referee) ; Putna, Ondřej (advisor)
The bachelor thesis focuses on the analysis of the issue of district heating (DH) with regard to legislative changes in the European Union. The first part deals with the analysis of the issue and the evaluation of the state of CZT in the Czech Republic. The European Union's position on climate change, caused by increasing greenhouse gas emissions, which are significantly produced by DH sources, is also discussed. The research part ends with an analysis of possible changes in the heating industry leading to the fulfillment of legislative requirements in the future. The second part of the bachelor's thesis deals with the elaboration of a case study of the change of the fuel mix for the heat source in the existing locality with the use of the technical-economic model. The main goal is to evaluate the usability of renewable resources (biomass, waste) as primary fuels instead of natural gas. The result of the practical part is a comparison of individual variants and changes in the cost of producing 1 GJ of heat compared to the reference variant.

Integration of Waste-to-Energy Plant into the District Heating Network with Existing Heating Plant
Kopecký, Václav ; Janošťák, František (referee) ; Putna, Ondřej (advisor)
The main two goals of this thesis are summarization of current state of waste management policies in the Czech Republic and introduction of possibilities connected with waste-to-energy strategy. This thesis is divided to 4~sections, each of them focused around different part of this complex problem, or issues directly connected to it. In the first part, state of waste management in the Czech Republic is discussed from several different points of view. Then, district heating is introduced as a solid platform for waste-to-energy facilities. The last two chapters present several other issues, connected with construction of new waste-to-energy plants and methods of optimization of long term rentability models.

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.

Civic amenities building
Pastorková, Michaela ; Svoboda, David (referee) ; Berková, Petra (advisor)
The aim of the diploma thesis is the design of the building of civic amenities in Hodonín. In particular, the leisure centre. The thesis is divided into three parts. The first part of the thesis comprises architectural and structural designs, building physics assessment and energy certificate of the building. The leisure centre is a two-storey building with a flat green roof. It features various teaching rooms, including a language classroom, drama class, dance studios, technical facilities, and staff rooms. The superstructure consists of sand-lime block walls and pre-stressed concrete panel floor and roof structure. The envelope wall is insulated with ETICS. The second part focuses on the design of selected building services: space and domestic hot water heating, cooling, ventilation, and rainwater management. The heat is supplied by local district heating. Mechanical ventilation with two air handling units and a fan-coil cooling system is designed to ensure optimal indoor air quality. The third part is dedicated to the spatial acoustics in the different rooms part of a building, with an emphasis on improving the acoustic comfort for different activities and teaching rooms.

EFFECTIVE UTILIZATION OF MUNICIPAL SOLID WASTE IN HEAT AND POWER SYSTEMS
Putna, Ondřej ; Klemeš, Jiří (referee) ; Ucekaj, Vladimír (referee) ; Stehlík, Petr (advisor)
The dissertation thesis is focused on the issue of energy recovery of waste. It contributes to optimization models developed in the author's workplace in the long term, which serve to simulate material flows in waste management and to search for an optimal waste management strategy. The main objective is to assess the potential for the use of heat produced in waste-to-energy plants as a key factor for the economy of these facilities. The thesis therefore represents an activity on the border of the fields of waste management and heating. Partial mathematical models were developed within the scope, for which it was necessary to collect input data, especially in relation with district heating networks. These models were then used in a comprehensive optimization model describing the integration of waste-to-energy plants with other heat sources. This main model was extended to include the environmental aspect.

Biomass in heating systems of cities and villages - I
Soudek, Ondřej ; Pavlas, Martin (referee) ; Máša, Vítězslav (advisor)
Point of this bachelor’s thesis is in acquainting with district heating problems. Emphases is posed for a technologic items of this system. Present trend is the cause of dissemination of biomass utilization in district heating over liberal possibility of distribution of heating. So bachelor’s thesis deal with vignette common fossil fuel. A new district heating system realization visualize extensive project and include project of thermal source, junction exchange station and heat distribution.
