• Design analysis of combined gas-vapour micro power plant with 30 kW air turbine

  Publikacja

  • M. Piwowarski
  • K. Kosowski

  - POLISH JOURNAL OF ENVIRONMENTAL STUDIES - Rok 2014

  The article presents basic results of the design analysis of a combined gas-vapour micro power plant with a waste-heat boiler without exhaust reheat, working in the vapour section in the Organic Rankine Cycle (ORC) system. The analysis concerned working media most frequently used in those types of power plants and planned to be used in future. The object of the analysis was a micro power plant with a 30 kW gas (air) turbine for...

  - ENERGY CONVERSION AND MANAGEMENT - Rok 2024

  The efficiency of power plants with steam or gas turbines depends on the efficiencies of a thermodynamic cycle and devices implementing this cycle. In the case of high power outputs, we cannot expect a significant increase in the efficiency of individual devices. Therefore, what remains is to increase the efficiency of the implemented thermodynamic cycle - the complex Rankine cycle in the case of steam turbines or the extended...

• Revalorization of the Szewalski binary vapour cycle

  Publikacja

  • P. Ziółkowski
  • J. Hernet
  • J. Badur

  - Archives of Thermodynamics - Rok 2014

  The aim of the paper is to revalorizate of the Szewalski binary vapour cycle by analysing thermodynamical and operational parameters of this cycle. This was carried by accessible numerical CFM (Computational Flow Mechanics) codes type, by step-by-step modeling of separates apparatus. The binary vapour cycle is providing steam as the working fluid in the high temperature part of the cycle, while another fluid - a low boiling point...

• Control of a vapour microturbine set in cogeneration applications

  Publikacja

  • W. Włodarski

  - ISA TRANSACTIONS - Rok 2019

  Systems with microturbines are implemented for local generation of heat and electricity. This paper presents the analysis of control concepts for a vapour microturbine set with a generator with permanent magnets, intended to work in small heat and power plants. Control system variants differed by the selection of controlled signals and set parameters. Possible ways of control were discussed and compared with experimentally determined...

  Publikacja

  • M. Urbanowicz
  • B. Zabiegała
  • J. Namieśnik

  - ANALYTICAL AND BIOANALYTICAL CHEMISTRY - Rok 2011

  The main objective of this review is to critically evaluate recent developments in solventless sample preparation techniques. The potential of a variety of sample preparation techniques based on solid- and vapour-phase extraction techniques is evaluated. Direct thermal extraction and derivatization processes to facilitate the extraction of analytes in different areas are included. The applicability, disadvantages and advantages...

• Carbon Dioxide and Water Vapour Fluxes of a Alkaline Fen and Their Dependence on Reflectance

  Publikacja

  • W. Ciezkowski
  • T. E. Berezowski
  • M. Kleniewska
  • J. Chormanski

  - Rok 2018

  This study shows results of parallel measurements of greenhouse gases fluxes (carbon dioxide and water vapour) and canopy reflectance of alkaline fen. Fluxes were measured using eddy-covariance technique on micrometeorological station located in the Upper Biebrza Basin (NE Poland) in Rogożynek Village. Study site is located in the Biebrza National Park which was established to protect one of the biggest coherent lowland wetland...

• Case study of water vapour transmission properties of EPDM façade membranes

  Publikacja

  • A. Ambroziak
  • S. Dobrowolski

  - Archives of Civil Engineering - Rok 2021

  This research aimed to investigate the water vapour transmission properties of chosen EPDM membranes applied in façade and window systems under laboratory tests. The applied procedure included in national and international standards utilized for the laboratory tests of water vapour transmission properties of EPDM membrane is described. Two main types (outside and inside types) of EPDM membranes are laboratory tested. The authors...
