Crankcase Ventilation of the Internal Combustion Engine
Zavadil, Martin ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
This thesis has been written out as a literature review. This work is focused on crankcase ventilation systems of internal combustion engines. The aim was to describe the origin of bow-by in different parts of engine, the principle of operation of individual components and a description of design solution for different types of engines. The work also describes the differences between crankcase ventilation systems of motorcycles and trucks. The last chapter is a description of used design solution of crankcase ventilation system for the selected engine VW 2.0TDI. In conclusion the work outlines possible developments in the field. The work also includes image attachments approaching the issue and design solutions.

Design and development of the electrostatic precipitator
Kvasnička, Karel ; Radil, Lukáš (referee) ; Ptáček, Michal (advisor)
This bachelor thesis deals with the design of an electrostatic precipitator and familiarization with the problems of separation on these separators. The aim of this work is to construct a functional model of an electrostatic precipitator. The principle of operation and design will be described. In addition, the design of a separator is elaborated, which was subsequently realized and experimentally verified in the CVVOZE Power Laboratories Research Infrastructure. The first part deals with the description of the legislation on air protection, the most frequent input material of separators and descriptions of the basic types of separators. In addition, the electric separator, its area of use, construction and individual components, as well as the undesirable operating state of the separator, are further elaborated. In the second part are presented the equations and calculations for the design of the separator. In the next part, the separator designer and his laboratory tests are described. The separator was subjected to basic voltage tests from the viewpoint of its operating voltage. Its functionality fits the realized experiments up to 30 kV. On the basis of this work and the production of the equipment, it is possible in the future to test the properties of flue gases and other gases.

Multicyclone treatment behind biomass boiler
Vafek, Petr ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
The diploma thesis deals with multitube cyclone changes leading to improve separating efficiency of solid particles. The thesis begins with theoretical part, in which the attributes and types of solid particle separators focusing on cyclones are presented. The practical part begins with separating efficiency and pressure drop calculation of the specific multitube cyclone. Subsequently the separating problem is explained and the changes leading to eliminating this problem are presented and evaluated. In the last and main part of thesis the design project including piping design and fan choice is created.

Thermal stability of the biomass combustion process
Grygar, Jan ; Špiláček, Michal (referee) ; Poláčik, Ján (advisor)
This bachelor thesis is focused on fne particles, which are produced by small combustion units, and their reduction. The frst chapter deals with the issue of fne particles, their creation, composition and their impact on man and the enviroment. The last chapter deals with the design of solution for reducing of emissions of small biomass combustion units.
