    • A Way to Use Waste Heat to Generate Thermoelectric Power 

      Autor: Brázdil , Marian; Pospíšil , Jiří
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      In recent years there has been rising interest in thermoelectric generation as a potential source of electric power using waste heat. This paper describes thermoelectric power generation from waste heat from biomass boilers, ...

    • EFFECT OF TUBE PITCH ON HEAR TRANSFER IN SPRINKLED TUBE BUNDLE 

      Autor: Kracík , Petr; Pospíšil , Jiří
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Water flowing on a sprinkled tube bundle forms three basic modes: the Droplet mode (the liquid drips from one tube to another), the Jet mode (with an increasing flow rate, the droplets merge into a column) and the Membrane ...

    • Heat Exchangers for Condensation and Evaporation Applications Operating in a Low Pressure Atmosphere 

      Autor: Kracík , Petr; Pospíšil , Jiří; Šnajdárek , Ladislav
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      This paper presents a state-of-the-art study of a heat transfer process in liquid spraying heat exchangers placed in a vacuum chamber. The experimental case studied here describes the behavior of a falling film evaporation ...

    • High-speed rail network and periodic timetable: a comparative analysis of operational concepts 

      Autor: Drábek, Michal; Mazel, Dominik; Pospíšil, Jiří
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      This paper compares chosen European high-speed railway (HS) networks in terms of their offer of HS passenger service. The criteria chosen for comparison are network topology, degree of service periodicity and degree of ...

    • OPTIMALIZATION OF AFTERBURNER CHANNEL IN BIOMASS BOILER USING CFD ANALYSIS 

      Autor: Pospíšil , Jiří; Lisý , Martin; Špiláček , Michal
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      This contribution presents the results of parametrical studies focused on the mixing process in a small rectangular duct within a biomass boiler. The first study investigates the influence of a local narrowing located in ...

    • SIZE ANALYSIS OF SOLID PARTICLES AT THE EXPERIMENTAL DEVICE FOR MULTI-STAGE BIOMASS COMBUSTION 

      Autor: Hrnčířová , Michaela; Špiláček , Michal; Pospíšil , Jiří
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      This paper presents the results of an analysis of ash content particles produced in biomass combustion at an experimental device. The main parts of the device are: the water heater, the gasifying chamber, the air preheater, ...
