Fluidized-bed Incineration of Dry Stabilized Sewage Sludge III.
Pohořelý, Michael ; Moško, Jaroslav ; Durda, Tomáš ; Svoboda, Karel ; Šyc, Michal ; Hartman, Miloslav ; Punčochář, Miroslav
In the report, it has been shown how to effectively burn dry stabilized sewage sludge in the fluidized-bed reactor with a stationary bubbling bed in oxy-fuel process.
Treatment of Flue Gas from Waste Incineration by Sodium and Calcium Based Sorbents.
Zach, Boleslav ; Pohořelý, Michael ; Šyc, Michal ; Svoboda, Karel ; Punčochář, Miroslav
This paper is focused on properties of sodium and calcium based sorbents in relation to simultaneous dry flue gas treatment from SO2, HCl, NOx, solid particles, and polychlorinated dibenzodioxins and dibenzofurans (PCDD/F). The most important differences between the two sorbent types are: the effect of temperature and moisture of flue gas on the sorption process, reactivity towards individual acid components in the flue gas (thermodynamic equilibrium and kinetics), and solubility of air pollution control residues.

Based Sorbents for Dry Sorption of Acidic Compounds from Flue Gas from Municipal Solid Waste Incineration Plants.
Zach, Boleslav ; Pohořelý, Michael ; Šyc, Michal ; Svoboda, Karel ; Punčochář, Miroslav
The paper compares sodium and calcium based sorbents for the dry treatment of flue gas from waste-to-energy plants with respect to their surface, reactivity to individual acid compounds in the flue gas and process conditions. The emphasis is on the dry flue gas treatment at temperatures below 250 °C. Commonly used stoichiometric dosages of sorbents are compared in relation to the mass of sorbent used. In addition, an experimental unit for testing of dry flue gas treatment is introduced.

Construction of Equipment for Testing of Operating Conditions of Fabric Filters on Real Flue Gases
Pohořelý, Michael ; Zach, Boleslav ; Šyc, Michal ; Svoboda, Karel ; Punčochář, Miroslav
This report focuses on the design of an experimental unit intended for testing of operating conditions of dry flue gas treatment on fabric or ceramic catalytic filters. Individual part of apparatus are described in detail and the reasons for the design choices are stated. A part of this report is also a 3D model of the apparatus created in AutoCAD.
Analysis of Bottom Ash from Municipal Solid Waste Incineration Plants
Krausová, Aneta ; Šyc, Michal ; Kameníková, Petra ; Zach, Boleslav ; Pohořelý, Michael ; Svoboda, Karel ; Punčochář, Miroslav
Struska ze spalování komunálních odpadu obsahuje radu materiálu, které mohou být dále využity jako druhotné suroviny, zejména železné a neželezné kovy, nekteré vzácné kovy a kovy vzácných zemin nebo napríklad sklo. Minerální frakce je po vytežení cenných surovin, vhodnou náhradou prírodních materiálu ve stavebním prumyslu. Významným benefitem, pri zpracování strusky, je pro provozovatele spaloven také redukce poplatku za skládkování. Řada spaloven v Evropě je vybavena separačními linkami pro získávání železných a neželezných kovu. V České republice je linka pro získávání neželezných kovů instalována na spalovne SAKO Brno, ostatní dvě spalovny separují pouze snadno dostupný objemný železný šrot. Pro posouzení využitelnosti a při rozhodovávání o aplikaci vhodné technologie pro úpravu strusky je nezbytná znalost jejích fyzikálních vlastností a materiálového složení, které je značně variabilní a závislé na složení spalovaného odpadu. Analýzou strusky z českých spaloven bylo stanoveno materiálové složení.

Characterization of MSWI Bottom Ash and Assessment of Resource Recovery Potential
Šyc, Michal ; Kameníková, Petra ; Krausová, Aneta ; Zach, Boleslav ; Pohořelý, Michael ; Svoboda, Karel ; Punčochář, Miroslav
Bottom ash from municipal solid waste incineration contains valuable components that can be recycled as secondary materials, such as ferrous and non-ferrous metals, rare earth elements, glass etc. Metal-free mineral fraction is reusable in construction industry. The composition of bottom ash is highly dependent on the composition of incinerated waste but in average can be around 5–13 % ferrous metals, 2–5 % non-ferrous metals, 15–30 % glass and ceramics, 1–5 % unburned organics and 50–70 % mineral fraction. Several incineration plants in Europe are equipped with advanced systems for metals recovery, mostly based on magnetic separation of ferrous metals and separation of non-ferrous metals usually by eddy-current separators. To study the possibilities of bottom ash treatment in the Czech Republic it is necessary to obtain data about the bottom ash composition and evaluate the potential of resource recovery.

Design of Apparatus for Testing of Catalytic Filters for Treatment of Flue Gas from Waste-to-Energy Plants
Zach, Boleslav ; Pohořelý, Michael ; Šyc, Michal ; Svoboda, Karel ; Punčochář, Miroslav
The presentation focuses on design of apparatus for testing of catalytic filters. Catalytic filters enable simultaneous cleaning of flue gas from particulate matter, sulfur dioxide, nitrogen oxides and organic compounds (as well as chlorinated organic compounds such as polychlorinated dibenzodioxines and dibenzofuranes). This technology could be suitable for small waste-to-energy plants because of small capital costs and small or no production of wastewater.
