Fluidized bed boiler for burning coal and wood 150t/h
Popelka, Ondřej ; Lisý, Martin (referee) ; Skála, Zdeněk (advisor)
This thesis is focused in calculation and designing of fluid bed boiler for burning coal and wood biomass in the form of wood chips. The uniqueness of fluidized bed boiler is circulating fluidized layer and cyclone ash separator from flue gases beyond the combustion chamber.Work was divided into several parts due to different parameters of the fuel.. Stoichiometry calculations, emissions calculations, enthalpy of combustion and flue gas desulphurization calculations are performed in various parts.Further, calculating of the losses of boiler and its efficiency comparing to the calculation and design of each heat transfer surfaces was also solved so that resulting size and quantity meet the required specifications.Drawn set of this designed boiler based on calculations is included in the annex to this paper.
Desulphurisation of flue gas from pulverzided coal boiler,Tp Olomouc
Kozumplík, Ondřej ; Lisý, Martin (referee) ; Skála, Zdeněk (advisor)
The aim of this thesis is to design a desulphurisation device for the pulverized coal boiler K3 in heating plant Olomouc. In this boiler, coal with sulphur content is burnt. Emissions SOx from the boiler output are much higher than the emission limits for SOx, which comes into force 1.1.2016. Therefore it is necessary to build a desulphurisation device, which will cause a significant reduction of SOx emissions and compliance with the emission limits. The thesis consists of two parts - theoretical and practical. The theoretical part states SO2 emission limits and describes various methods for flue gas desulphurisation. In the practical part I chose a semi-dry desulphurisation method with fluid reactor. It determines a stoichiometric amount of combustion air and determines the boiler efficiency. For the required parametres is given a calculation of desulphurisation, the design of some parts of the device and design arrangement.

Desulphurisation of flue gas fuidized bed boiler.
Miklík, Tomáš ; Slezák, Pavel (referee) ; Skála, Zdeněk (advisor)
The aim of this thesis is to design a desulphurization device for the fluid boiler. In the fluid boiler, fuel with extremely high sulphur content is burnt and the combustion products are not desulphurized to the required level, therefore it is necessary to build a desulphurization device. The thesis consists of two parts – theoretical and practical. In the theoretical part I stated the emission limits of sulphur dioxide, elaborated possible desulphurization methods and described the sorbets suitable for desulphurization. In the practical part I chose a dry desulphurization method with fluid reactor, to which a dry sorbent on the basis of lime hydrate is dosed. For the required parameters, I designed the whole desulphurization equipment including cloth filters, all necessary silos and major components. It is a design proposal with a layout and a spatial model.
