Black Coal Mining in Czech Rep
Vínovský, Jan ; Škorpík, Jiří (referee) ; Lisý, Martin (advisor)
Throughout history, coal mining has dominated the 19th and especially the 20th century. The period of decline in mining began in the 90s. Between 1990 and 2019, there was a decrease of 88.13%, specifically from 30,714 kt to 3,645 kt of mined coal per year. Currently, only four active mines are in operation and the other two are in a conservation state. The forecast for the future of the sector is very unfavorable. In addition to the economic crisis, there are also reserves of extractable coal, which are currently around 25,000 kt. It is currently planned to end mining at the ČSA and Darkov mines at the turn of 2020 and 2021, ČSM Mines should be closed by 2022 at the latest, which will completely end black coal mining in the Moravian-Silesian Region and the entire Czech Republic.

Effective Heating Systems for Family Houses
Čulík, Martin ; Poláčik, Ján (referee) ; Lisý, Martin (advisor)
This bachelor’s thesis deals with a summary of basic information and possibilities of heating family houses. Designing the right type of heating system is really important factor for a good operation of heating and also for the right comfort inside of the house. There will be description and calculations of the specific house in the second part of the thesis.
New Technologies for Family House Heating
Bořil, Martin ; Brázdil, Marian (referee) ; Lisý, Martin (advisor)
The subject of this bachelors thesis is a new technology for family house heating. The first part will be about searching available solutions on the market. In the second part, this knowledge will be applied to a real house with already instaled heating system for comparing with other heating methods.
Gasification Technologies in the Czech Republic and Abroad
Kunert, Šimon ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
This bachelor's thesis deals with gasification technologies in the Czech Republic and abroad. The first part describes brief history of gasification, characteristics of the process, the most important types of equipment intended for this purpose, what are their properties and possibilities of use in practise. A separate part is dedicated to biomass gasification. The second part is dedicated to companies and institution that have dealt with this technology. There is a place of business in which the company operates, and a brief description of their equipment with specific use in practice.
Risk of Waste Combustion in Small Boilers
Kopecká, Eliška ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
The bachelor's thesis deals with the issue of waste combustion in small boilers. In the first chapter, the components of household waste are specified in more detail, as well as the pro-duction and possible waste management. The second chapter is focused on the formation of the pollutants during combustion and their impact on the environment and the human organ-ism. In the third chapter is presented the process of the operation of the waste incinerator and there are mentioned the limit values of the emissions that are released into the air. The fourth chapter deals with the reason for the origin and the comparison of the pollutants aris-ing from combustion in small boilers. Materials defined as household waste and pollutants released from them during incineration are described here. In the end, the results of the the-sis are evaluated.
Energy Mix in the Czech Republic
Fojtl, Martin ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This bachelor’s thesis addresses the mixture of energy mix in Czechia. The first part is focused on the evolution of energy mixture up to present days. In the next part, the expected development of the mixture is described from the state energy policy and ecological points of view. Lastly, in the final section, there is a comparison of compositions of electric energy source between Czechia and other countries of a European Union.
gasification of biomass with a mixture of oxygen and water vapor
Chlubna, Martin ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
The aim of this diploma thesis is to describe the gasification of biomass with a mixture of oxygen and water vapor. The theoretical part is focused on the gasification process, gasification reactors and the quality of the resulting gas. In the experimental part we look for the ideal ratio of oxygen to water vapor, which are used as gasification media. Subsequent measurements are carried out on the fluidized bed reactor, the results of which are further processed and evaluated.
Návrh koncepce tepelné elektrárny

This diploma thesis deals with the design of a thermal scheme of steam power plant. The introductory part of the thesis is dedicated to theory about thermal power plants, especially those with supercritical steam parameters. In the following parts, there is a design of the thermal scheme of the coal burning power plant. First separate parts, then all interconnected. The last chapter deals with energy and media balance involved in the process.
RDF Grate Biomass Boiler
Malíková, Veronika ; Křemínský, Pavel (referee) ; Lisý, Martin (advisor)
The diploma thesis deals with the design of a grate boiler for the combustion of a mixture of RDF and wood chips with the specified output and parameters of superheated steam. The introduction consists of stoichiometric calculations and determination of the thermal efficiency of the boiler. The thesis is devoted to determining the dimensions of the boiler, heat transfer calculations, determining pressure losses, checking the heat balance and chlorine corrosion.
