This thesis deals with really small cyclone separators which could be used for a flue gas purification. The search section discusses particle formation in combustion, their characteristics, any other flue gas cleaning options and last but not least, a cyclone separator where is the effort to understand all the influences that contribute to a cyclone’s resulting separability. The Experimental section analyses a calculation of the cyclone and theoretical separability, a verification of this separability using a cyclone created by a 3D printer. On the one hand, the verification was made by gravimetric analysis which is intended for a bigger particles, on the second hand, it was made using the PALAS which is aimed at particles in µm. There is also a comparison of theoretical and measured values in this section.

The master’s thesis deals with thermal treatment of biomass and with reduction of emission, which originate during this process. First part speaks commonly about biomass incineration and about technologies for emission reduction, especially cyclones. Practical part of this paper involves description of multicyclone evaluation by different authors and the comparison on of the evaluation on a case study of concrete multicyclone.

This thesis is devoted purification of a gas stream with solid and liquid particles. The problem described in the thesis is connected with a real industrial case – problem of operated waste gas incineration plant. Waste gas going to thermal incineration to flame of natural gas combustion contains solid and liquid particles. Presence of particles causes fouling of waste gas preheater. The main objective of thesis is analysis of situation and operating and space limitations and design of a suitable type of particle collector to reliable elimination of particles from waste gas before entering the gas preheater and thus to mitigation of fouling of preheater heat transfer area.

This thesis deals with aspects of the dust particles which occur in gaseous products from biomass combustion. The thesis introduces technologies by which solid particles capture from a combustion flow can be implemented. Principles and technical means of dust particles separation in mechanical separators are put in focus primarily. The thesis is concluded with a technical design of a cyclone separator.
