Diploma thesis deals with analysis of energy resources. The aim is to map the potential of renewable resources in the Czech Republic and through multicriteria decision making to assess the potential investment options in renewable energy in the Czech Republic.

Diploma thesis The possibilities of using renewable energy sources in a family house in the village of Hovězí is divided into two parts. The theoretical part describes the types of renewable resources and the possibilities of drawing up the subsidy program Kotlíková dotace. In the practical part describes the object of the family house. For this house the necessary attachments were made for the possibility of drawing the Kotlýkové subsidy and the most suitable source of heat was chosen with the calculation of the costs of implementation and evaluation of the payback period.

This master's thesis deals with the design of stoker-fired boiler for combustion of biomass. The main points of work are stoichiometry calculation of combustion, determining the dew point of flue gas, calculation of losses, which ones serves for determination of boiler efficiency, dimension design and detail calculation of thermosetting surfaces. In the last chapter is numbered total balance and real thermal efficiency of boiler.

The master´s thesis deals with steam boiler design that burns contaminated wood with output 55 tons of steam per hour, steam pressure 4,2 MPa and temperature 423 °C. First two chapters focuses on stoichiometry and calculation of heat losses and boiler efficiency. Great part of thesis constitutes of thermal and dimensional calculations of every heat transfer surface. Some specific boiler parts are described considering special fuel properties. Final chapters contain pressure losses calculation of flue gas and heated medium for pumps and fans design. Drawing is also part of the work which is included as an attachment.

The thesis examines the suitability of a CHP project in Bystřice nad Pernštejnem, a small town in Vysočina region, Czech Republic, which is currently supplied by biomass central heating. It reviews situation and availability of renewable energy sources and opportunities for CHP both in the Czech Republic and in Europe, including the context of current global developments. The opening chapters are followed with the renewable energy project for Bystřice nad Pernštejnem itself. The current technology, availability of biomass fuel for a potential future project, and possible development of energy sources in the town are analysed. Three alternative solutions for the CHP plant are suggested, with proposal for the technology and economic analysis, and possible future steps of the town council are discussed.

Biomass gasification using air with addition of oxygen can be the right way to increase the quality of the syngas produced. This thesis aims to characterize the gasification process using oxygen-enriched air and verify its effect on the gas. The theoretical part deals with description of the technology with an emphasis on various gasifying agents and different possibilities of increasing gas quality. The practical part contains the results of measurements on the atmospheric fluidized bed reactor and their evaluation. The experiment was performed with various oxygen enrichment taking into account the capabilities of the equipment used.

This thesis deals with design of hot water grate boiler, where the output is water with parameters 130 °C and pressure 16 bar. In the content of the whole thesis is gradually introduced a stoichiometric calculations, which is based on the specified fuel – wood chips. This is followed by the design of the individual heating surfaces according to the thermal calculations given in the thesis. Finally, the calculation is extended by hydraulic and aerodynamic losses. Dimensional design, as a basic scheme, is shown at thesis. More detailed drawing documentation is attached to this thesis.

The diploma thesis deals with a temperature field in a solid fuel during the combustion process. At the beginning of this thesis, research of available literature was conducted to obtain information about the composition of wood, properties affecting the combustion process, and the basics of heat transfer. Afterward, the temperature profiles of the samples were recorded during the measurement in the observation furnace. The temperature profiles of samples of six different sizes which were made of spruce and beech wood were subsequently evaluated and compared. Based on experimentally obtained data, a mathematical model was created in the OpenModellica software. Finally, the results of the mathematical model were compared with experimentally obtained data and appropriate conclusions were deduced.

This thesis deals with issue of grate boilers. It describes their properties, function principles and usage. The main part of this thesis is design of grate boiler burning biomass with steam output 96.4 tons/hour. Steam temperature and pressure at the output are 490 °C and 8.1 MPa.

Master thesis deals with design of electrostatic precipitator for domestic wood-burning appliances. In the opening chapters, principles of electrostatic precipitation are described and a study of existing electrostatic precipitators for domestic combustion devices is made. In the practical part of the thesis, a mathematical model of electrostatic precipitator was created. Based on the mathematical model, electrostatic precipitator was designed and its performance parameters predicted.
