Use of offsetting methods to reduce the impact of CO2 production
Chmelík, Ondřej ; Brummer, Vladimír (referee) ; Krišpín, Jan (advisor)
The aim of the bachelor thesis is to assess the selected CCS and CCU methods as procedures for the capture and utilization of the greenhouse gas CO2. The thesis assesses the legislative conditions and opportunities that have led to the development of CCS and CCU. The analytical part of the thesis focuses on a simplified assessment of the selected methods in terms of their application in the Czech Republic.

Up-to-Date Medium Capacity Waste-to-Energy Unit
Krišpín, Jan ; Krejčí, Tomáš (referee) ; Bébar, Ladislav (advisor)
The submitted Master Thesis deals with the technological/mechanical solution of an up-to-date medium capacity waste-to-energy plant. Operational requirements and basic parameters related to a concrete region are specified in the introduction of the Thesis. This is supplemented by a flow-sheet of the plant with the description of main process subsystems. To meet the goals of the Thesis basic balance information is summarized and related schemes included. These data represent principal inputs for the on-site plant as well as basic parameters for the design of key equipment. These pieces of equipment are schematically drawn including their basic parameters and a description of construction. All the available innovative solutions are taken into account. The Thesis provides also a technical-economic analysis for being able to evaluate the overall project.

Integration of material and energy utilization of sewage sludge
Zakov, Tomáš ; Brummer, Vladimír (referee) ; Krišpín, Jan (advisor)
This master thesis deals in first part with options and trends on field of municipal sewage sludge management. Further thesis describes legislation in relation with sewage sludge and its incineration in European union and also in Czech republic. Second part of thesis deals with design of mechanism for material and energetic use of sludge. In design is progressively processed chioce of aparates and material and energetic balance. This data are further used for mechine technical solution of the unit. Disposition of the unit is done acording to chosen and calculated parameter of chosen aparates. Economical evaluate of project if based on investment and operation costs and capacity design of unit in the end of thesis.

Modelling of air flow in combustion chamber ZKG
Krišpín, Jan ; Lisý, Martin (referee) ; Špiláček, Michal (advisor)
The subject of the submitted bachelor thesis is a description of chemical and physical behavior of biomass, methods of energetic transformation of biomass, processes in a combustion chamber during burning and primarily flowing of combustion air. A part of this thesis is a modelling of an air flow in the combustion chamber using the finite elements method with an evaluation and a suggestion of construction changes of the combustion chamber.

WtE plant carbon footprint
Staňková, Lucie ; Brummer, Vladimír (referee) ; Krišpín, Jan (advisor)
The value of the carbon footprint of the WtE plant is necessary for reducing emitted greenhouse gases. In this paper, research on carbon footprint assessment is conducted, while the principles for calculating the carbon footprint according to EN 15978 standard for the sustainability of construction works through the whole life cycle are applied. This methodology is enriched with the technological unit's carbon footprint, including processes The proposed computational model is applied to determine the carbon footprint of the WtE plant Evecont. The main contribution to the carbon footprint of the WtE plant is the use phase due to carbon dioxide in the flue gas. A substantial carbon footprint reduction can be achieved by incorporating technology to capture carbon dioxide from the flue gas (CCS technology). The results achieved for the WtE plant are compared against landfill and heat from the central heat supply system. This work provides a tool that can be applied to other process industry units, allowing the carbon footprint to be calculated in detail and benchmarks to be established for the comparison of new projects.
