Alternative pellets production
Janíček, Jakub ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This bachelor thesis contains a review of possible technologies for the production of pellets and briquettes. Emphasis is placed on technology for the treatment of biomass for further use. Easy to biomass use is subject to the homogenization and adjusting to the wood chips, pellets or briquettes. The final part of thesis is concerned with energy and economic balance of a specific production line pellets.

Pellets production
Janíček, Jakub ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This thesis describes the characteristics, treatment and processing of biomass into a form shaped solid biofuels. It contains an overview of the requirements for pellets quality, possible means of improving the quality of pellets and methods of processing materials in order to achieve the desired quality of pellets. This thesis has shaped economic production of biofuels and shaped the recommendations for the design of pelletizing production line alternative pellets.

Metal waste processing system from cutting processes
Partlová, Veronika ; Osička, Karel (referee) ; Chladil, Josef (advisor)
Diploma thesis will be focuses on the processing of steel chips, explanation of general con-cepts, the division of chips according to their origin, their types and examples of some machines that are related to the chip processing system. It will also describe which law to follow when sor-ting waste like this, how to recycle it and how much this topic is connected with the ecological point of view. The second part of the work will be focused on the processing of the aluminium waste from the production of aluminium components. It contains a specific example of the calculation of a proposal to change the treatment of the waste and the return on investment in this change. The reason why to undergo this change is described too and in what way it will be beneficial.

Technological Possibilities of Using Waste Claystone for Manufacturing Refractory Grog burned in blast furnaces
Konečný, Martin ; Tvrdík,, Lukáš (referee) ; Nevřivová, Lenka (advisor)
Aluminosilicate refractory grog are being manufactured by firing refractory clays, claystone and shale. Firing takes place mainly in rotary or blast furnaces. However, when adjusting the raw material before firing in blast furnaces, the formation of the fine clay particles takes place. It is not possible to fire the fine particles in blast furnaces the usual way, which leads to the generation of waste. There is a possibility, however, to form briquettes of these particles, which can be fired in blast furnaces. This solution also brings the possibility of adjusting the mixture by using correction raw materials or other types of clay. Using this method, it is possible to produce a special refractory grog with specific properties.

Production of refractory aggregate in blast furnaces
Zemánek, David ; Tvrdík,, Lukáš (referee) ; Nevřivová, Lenka (advisor)
Firing of refractory aggregate takes place in blast or rotary furnaces. Raw materials for firing are refractory clays, claystones and shales. Sorting and sieving is performed before firing, in which occurs to formation of the fine clay. This waste is not useful for firing in common way in blast furnaces. Possibility, how to solve this problem, seems to be briquetting of fine clays. This method of proccesing fine clays brings with it new possibilities in refractory aggregate production. By adding a suitable correction material, such as mullite powder, special refractory grog with required properties can be produced on customers wishes.
