The Diploma’s work deals with design to use new methods of cleaning the combustion products for the incinerator of biomass, which guarantees removal of dioxins from the combustion products. Thesis depicts methods of cleaning the combustion products, like ADIOX, using ceramic filters, catalytically filters and methods REMEDIA. Thesis compares constituent methods in terms of effectiveness and according to economic analysis applicable to incinerator of biomass-power output 1 MW. Thesis acquaints with the conception of biomass and with thermic processing, which produces dioxins. Thesis processes using biomass in Czech Republic and plan for using in the future. Thesis processes detailed model of filter using the fabric filters REMEDIA. Suggestion of position of the filter and it is connection to original products line of cleaning the combustion products. Increased pressure loss of the new pipework way and increased consumption of ventilator incinerator is calculated for the new connection. In quest of decreasing the thermal loss of combustion products and in quest of increasing safety of operation is calculated and in quest of increasing safety of operation is calculated proposal of isolation for the filter and pipework. In the end of the thesis is depicted using the technology for decreased amount of dioxins from the fly ash from dioxin filter.

Visits were also paid to municipal wastewater treatment plants to get an overview over the municipal wastewater treatment situation.

The greatest challenge for Wuhan is to construct wastewater treatment plants for the around 3.5 million people that still discharge their wastewater directly to rivers and lakes, rather than to improve the industrial wastewater treatment further. The treatment rate of the industrial wastewater has reached 97%, but the municipal wastewater treatment rate has only reached 70%. After the visits to the selected companies and municipal wastewater treatment plants the conclusion was made that Swedish technologies and expertise can be applied to the following areas; handling sludge from the wastewater treatment plants, construction of waste incineration plants and handling flue gas and dioxins. Most of the visited companies could follow the wastewater standards. Although much can be done to improve their technologies further, this is not done since it is too expensive. It is possible for Wuhan to apply stricter local wastewater treatment standards. This could be used as a tool to make companies invest more money in improvements of their technologies.

The objective of the presented diploma thesis is reduction of nitrogen oxides from the flue gas stream on catalyst under non-standart conditions. Emphasis is places on the description of selected pollutants in flue gas (especially nitrogen oxides), legislative requirements for air protection and technologies for removal of nitrogen oxides, expecially methods of selective catalytic and non-catalytic reduction. The practical part is devoted to the reduction of nitrogen oxides by selective catalytic reduction on a pilot plant INTEQ II in the laboratory NETME Center. The subject of interest is the determination of the NOx reduction efficiency depend on the temperature for selected catalyst. The end of the practical part pursues with comparison of measurement results and their evaluation.

The purpose of the thesis is to create preliminary design calculations to determine dimensions, weights and pressure losses of individual contaminated biomass combustion gas treatment nodes. The first part of the thesis deals with the definition of biomass as a fuel, legislative determination of allowed emissions and their description. Then the systems for combustion gas treatments are discussed given their brief description. The practical part focuses on shape designs, determining base dimensions of each type. Weights and pressure losses of individual versions are computed too. In the last part the individual versions are solved with real values and compared to each other.

This thesis mainly deals with the thermal treatment of waste - hazardous waste incineration and energy recovery municipal waste incinerators - their descriptions and analysis of legislative conditions. The flue gas cleaning system energy production in different operating modes is assessed by energy and mass balances. Computational models are developed for this purpose. On this basis, productions of energy from thermal treatment of hazardous and communal waste were compared.

The main scope of thesis is to describe the pollutant removal techniques with a focus on heavy metals. With that relate chapters describing the formation of pollutants and their effect on human health. The thesis focuses on a detailed description of flue gas cleaning technology and its evaluation. Evaluation is shown in tables comparing emission measurement on waste incineration plant SAKO Brno, a.s. with emission limits. The thesis also briefly describes other options for municipal waste management.

Research of conditions when sulphure dioxide is absorbed from flue gas, is the main objective of this master's thesis. Efficiency of this flue gas cleaning was measured on an experimental device, which consist of an absorption column filled with structured packing’s, and another component so-called "O-element". Further, a possibility of upgrade this "O-element" to tread more flue gas is presented.

This diploma thesis deals with selected abatement techniques of nitrogen oxides (NOx) developed for large combustion plants. The first part describes selected NOx, their properties and explains the formation during combustion. Furthermore, there is an analysis of current legal legislation regulating the issue of emission limits. The third part presents selected primary and secondary measures that are widely used. The emphasis is placed on the description of selective catalytic (SCR) and non-catalytic reduction (SNCR). Finally, the basic design of these technologies for model combustion equipment is performed. The consumption of reducing medium and the volume of the catalyst for the mentioned techniques are calculated here. The estimate of selected operating and investment costs is a part of the basic scheme.

The topic of the diplome thesis is draft of the waste-to-energy plant for municipal waste with cogeneration of heat. Basic specification of project: Waste-to-Energy plant is facilitated by two rotary kilns of type operating in parallel. Further flue gas leaving the post-combustor enters a multicyclone unit to separate substatial portion of fly-ash. Heat of flue gas at the temperature of 1000°C generates superheated steam in a Heat Recovery Steam Generator (HRSG). Dry sorption process is appllied for flue gas treatment. Specifically sodium bi-carbonate is used for it. Products of reactions and remnants of dust are separated by a baghouse. Superheated steam, generated by two HRSG, presents the inlet stream of a condensing steam turbine with steam extraction. The diploma thesis contains calculation of major devices and basic economical and financial statement of project.
