    • Experimental and simulation study of CO2 breakthrough curves in a fixed-bed adsorption process 

      Autor: Nedoma, Marek; Staf, Marek; Hrdlička, Jan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      This paper focuses on the laboratory experiments of low-temperature adsorption of CO2 at elevated pressure and on the validation of our mathematical model with the data obtained. The numerical approach uses fitting of ...

    • Measurement of solid particle emissions from oxy-fuel combustion of biomass in fluidized bed 

      Autor: Červený, Ondřej; Vybíral, Pavel; Hemerka, Jiří; Mareš, Luďek
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      The presented work summarizes the results of the measurement of solid particle emissions from an experimental 30 kW combustion unit. This unit has been used for the research of oxy-fuel combustion of biomass in a fluidized ...

    • Experimental verification of the impact of the air staging on the NOx production and on the temperature profile in a BFB 

      Autor: Vodička, Matěj; Michaliková, Kristýna; Hrdlička, Jan; Skopec, Pavel; Jeníková, Jitka
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      The results of an experimental research on air staging in a bubbling fluidized bed (BFB) combustor are presented within this paper. Air staging is known as an effective primary measure to reduce NOX formation. However, in ...

    • Experimental verification of the efficiency of selective non-catalytic reduction in a bubbling fluidized bed combustor 

      Autor: Michaliková, Kristýna; Hrdlička, Jan; Vodička, Matěj; Skopec, Pavel; Jeníková, Jitka; Pilař, Lukáš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      Controlling nitrogen oxide (NOX) emissions is still a challenge as increasingly stringent emission limits are introduced. Strict regulations will lead to the need to introduce secondary measures even for boilers with ...

    • Theoretical and experimental study of water vapour condensation with high content of non-condensable gas in a vertical tube 

      Autor: Krempaský, Jakub; Havlík, Jan; Dlouhý, Tomáš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      This article deals with the possibility of separating water vapour from flue gases after oxyfuel combustion using condensation processes. Those processes can generally be described as condensation of water vapour in the ...

    • Applicability of Secondary Denitrification Measures on a Fluidized Bed Boiler 

      Autor: Jeníková, Jitka; Michaliková, Kristýna; Hrdlička, František; Hrdlička, Jan; Pilař, Lukáš; Vodička, Matěj; Skopec, Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      This article compares performance of selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR) applied on the same pilot unit, a 500 kW fluidized bed boiler burning Czech lignite. Correlation of the ...

    • Effect of membrane separation process conditions on the recovery of syngas components 

      Autor: Seghman, Petr; Krátký, Lukáš; Jirout, Tomáš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      The presented study focuses on inspecting the dependency between process conditions, especially permeate and retentate pressure and component recovery of H2, CO, and CO2 during a membrane separation of model syngas. ...

    • Analysis of parameters important for indirect drying of biomass fuel 

      Autor: Sabatini, Michel; Havlík, Jan; Dlouhý, Tomáš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      This paper focuses on biomass drying for the design and operation of an indirect dryer used in a biomass power plant. Indirect biomass drying is not as well described process as direct drying, especially when used for the ...
