Estimation of biogas production in biogas plant
Heger, Jan ; Vondra, Marek (referee) ; Touš, Michal (advisor)
The focus of this thesis are calculation methods for biogas yield estimation in biogas plant. The aim is to get acquainted with calculation methods and to determine their accuracy by calculation. Refining biogas production estimates can be useful for case studies, feasibility studies, or technical-economic assessments. The available calculation methods are tested on a case study where a comparison with the operational data measured in the biogas plant in Valašské Meziříčí is accomplished using the extended Buswell method and tabulated values. Comparing this case study, a result was obtained where the calculation by the Buswell method reached very accurate values, whereas the calculation by tabulated values differed more from the measured values and the method achieved a less accurate result.

Polyfunctional zone MOŘICE okr. Prostějov
Orinčák, Denis ; Vojtová, Lea (referee) ; Dýr, Petr (advisor)
The topic of the diploma thesis is the Mořice Agricultural Business Cooperative. (Hereinafter referred to as ZOD Mořice). This topic is a continuation of the pre-diploma project ZOD Mořice -Vitčice area. ZOD Mořice owns 4 complexes of agricultural facilities. Mořice - Vitčice - Vrchoslavice- Pavlovice u Kojetína. The main concept consists of the division of operations into individual complexes, according to the analyses and ideas of the investor. Vrchoslavice - livestock production (existing, not addressed). Pavlovice u Kojetína - business (proposal - lower years). Vitčice - housing for pensioners with limited mobility and independent pensioners (proposal -pre-diploma project). Mořice - architectural and urban planning study of the area, supplemented by housing units for workers and starter homes (proposal - diploma thesis). I am proposing to place silos and a biogas plant in the area and adding a building for recycling solar panels. The recycling operation will be in one of the existing warehouse buildings. I am also suggesting reserve areas for future use for the sale of homemade products. The most detailed part that is addressed in the thesis is the housing units. The housing units will be used, as service apartments and starter homes, possibly for housing for pensioners without mobility limitations. The concept follows the basic axis of existing buildings and streets. The design uses a housegarden relation. I am trying to preserve the structure of the village and not to create urban elements in it. The roofs are gabled. The facades made of brick strips are meant to make it clear that the houses are close to the industrial zone. I am separating the entire set of dwelling units from the agricultural area with a mound of earth that is on the site and has no other use.

Polyfunctional zone MOŘICE okr. Prostějov
Machová, Kamila ; Velehradská, Dagmar (referee) ; Dýr, Petr (advisor)
The thesis deals with the architectural-urban design of an agricultural complex belonging to the Agricultural Cooperative AGRISPOL, located in the eastern part of the village Mořice in the Prostějov Disctrict which belongs to the Olomouc Region. The actual assignment in its core builds upon the urban study of the pre-diploma project named "Revitalization of the Vitčice Agricultural Complex." The urban design of the agricultural complex focuses on the construction of a new biogas station, new grain storage facilities, the placement of a new building for small-scale business facility for the company Agricultural Cooperative AGRISPOL, the placemen and design of a new warehouse, the reconstruction of already existing buildings for grain storage, and the renovation of the existing building of the former cowshed into a garage and workshop for agricultural machinery repairs. Additionally, it includes the construction of residential spaces in the western part of the area, on the site of the former farm, which connects to the village square of Mořice. The dissertation thesis then provides more detailed elaboration on the development of the residential area and buildings. The residential buildings are designed as rectangular structures with pitched roofs and arranged in an imaginary square, which is enclosed by fencing at the corners, creating a semi-private enclosed courtyard space.

Polyfunctional zone MOŘICE okr. Prostějov
Janovská, Tereza ; Vojtová, Lea (referee) ; Dýr, Petr (advisor)
The task of the diploma thesis is to prepare an architectural-urban study of a large multifunctional complex of the AGRISPOL company in the village of Mořice. The proposal is to have a wide scope, design of biogas plant, storage facilities, silos, internal roads, accommodation and recreation. The agricultural centre owns four agricultural sites, Mořice, Vitčice, Vrchoslavice and Pavlovice near Kojetín. The topic of the pre-diploma thesis was the agricultural centre Vitčice. The main idea of the thesis was to design efficient communications, layout and arrangement of the biogas plant, revitalization of garages and workshops, design of storage halls for the purposes of the cooperative or for rent. The eastern part of the plot is designated for short-term housing and senior housing in the proposed nursing home, supplemented by services such as manicure, pedicure, hairdresser. These two units are divided into almost two identical buildings that resemble a hockey stick in shape. The combination of these two shapes has created an inner courtyard which serves as a garden/park for the adjacent accommodation units. The park will be freely accessible to the public. The capacity of the nursing home is 16 accommodation units. The units include a hallway, private bathroom and a living room with kitchenette. The capacity of the adjacent apartment building with an adjacent multifunctional part is 8 flats of 1+kk size and 9 flats of 2+kk size. The apartments are designed as starter housing for young couples or for accommodation of AGRISPOL employees. It is a form of short-term housing.

Polyfunctional zone MOŘICE okr. Prostějov
Pajerová, Silvia ; Vojtová, Lea (referee) ; Dýr, Petr (advisor)
The topic of the thesis is a polyfunctional zone in the area of ZOD Agrispol in the village of Mořice in the Prostějov district. The area is divided into two main parts in the design, namely agricultural production and housing. The production part of the area was designed conceptually and in mass, when the areas were complemented by new biogas plant and plant production. In detail, the area with the housing function for workers of the cooperative, for young families and housing for the elderly was designed within the work. The residential part is designed in the form of terraced houses and semi-detached houses with small gardens. The new development is inspired by a typical Moravian village and the village of Morice itself. The central semi-public space intended for the inhabitants of the designed site is open to the municipal park with the castle and the church, thus taking advantage of the potential of the pleasant location of the historic core of the village. The housing proposal adds materially to the currently missing edge of the park, whilst keeping the plan footprint of the former Dudek Farmhouse and materially separating the agricultural operation from the residential area of the village.

Treatment of thickened sludge from industrial wastewater
Peťovský, Patrik ; Procházková, Michaela (referee) ; Vondra, Marek (advisor)
The aim of the thesis is to present the problem of industrial sludge treatment and to identify and implement in laboratory conditions a suitable technology for the treatment of a specific industrial sludge, which is already partially thickened fermentation residues from the operation of biogas plants (BPS). Based on the research developed on available technologies for the treatment of waste sludge, the mixed evaporator was selected as a suitable technology. The advantage is the possibility of using the low potential heat from BPS CHP units under reduced pressure, which is often thwarted. The agitator in the evaporator ensures homogenization while increasing densification. The use of the technology results in a reduction in the volume of fermentation residues. The main part of the thesis deals with the design and implementation of a stirred evaporator for production. Experimental The plant was constructed on the premises of the LENP (Laboratory of Energy-Intensive Processes) at the Brno University of Technology. During operation, the functionality of the device and its applicability to several types of waste sludge were verified. The experimental results are mainly focused on the properties and behaviour of the fugate, or liquid fraction, of the fermentation residues. The fugate was concentrated from a raw state of 5.4 % dryness to a value of 20.9 % dryness, at which point it becomes a highly viscous and poorly flowing material. In an industrial plant where waste heat is wasted, a stirred evaporator may be a suitable device for sludge treatment or volume reduction. This leads to lower costs for storage, transport, and application as fertilizer to fields. With a suitable evaporator and agitator design, the evaporation principle can be used for less and more concentrated waste sludge. The resulting thickened product can then be fed to the finishing operations, allowing the distillate to be finished.

Ekonomické hodnocení provozu bioplynové stanice a její potenciální transformace k produkci biometanu
Lukašík, Jáchym
This work deals with the principles of biogas and biomethane extraction and the methods of their subsequent energy use in legislative conditions of the Czech Republic and explains the support systems of this resource, also in the conditions of other EU member states, with a more detailed focus on the situation in Germany. Subsequently, the real agricultural biogas plant is economically evaluated from the data on operation in previous years using static indicators, from which the future management is then predicted on the basis of revealed trends, using dynamic methods. The production of the analyzed biogas plant is then transferred to the operating aid environment in Germany and compared in key years. In the next part, investment financing strategies are modeled for biomethane cleaning equipment for use in transport, as bioCNG fuel, which recommend an adequate level of operating aid prices acceptable for the analyzed biogas plant. The results of the work help to assess the further probable development of the industry and determine the production limitations of the evaluated operator, which should be taken into account in the next stages of the development of operational aid strategies in the context of the maintenance of the production of such operations.
