  - Acta Geophysica - Year 2012

  This paper describes the research concerning precise short-time GPS solutions conducted in the Centre of Applied Geomatics, Military University of Technology, Warsaw, Poland. The data from ASG-EUPOS (Polish Active Geodetic Network) was processed using Bernese 5.0 software and EPN (EUREF Permanent Network) standards and models. In this study, the adapted 3-hour observation window is shifted every hour for obtaining hourly geocentric...

  - Year 2013

  A preliminary evaluation has been made of a possibility of bottoming of a conventional Brayton cycle cooperating with the CHP power plant with the organic Rankine cycle installation. Such solution contributes to the possibility of annual operation of that power plant, except of operation only in periods when there is a demand for the heat. Additional benefit would be the fact that an optimized backpressure steam cycle has the advantage...

• ENHANCED MASTER CYCLE - SIGNIFICANT IMPROVEMENT OF STEAM RANKINE CYCLE

  Publication

  • S. Głuch
  • M. Piwowarski

  - Year 2019

  The present paper focuses on an enhancement of the Master Cycle. In the first part, the paper presents a classical Master Cycle which is a modification of the double reheat Rankine cycle. This modification allows to slightly increase efficiency, resolves problems caused by superheated steam on bleeds and decreases mass flow rate of steam directed to reheat. These improvements include the implementation of a tuning turbine from...

  - E3S Web of Conferences - Year 2018

  An important goal, implemented by EU countries under the Europe 2020 strategy, is sustainable development, which includes supporting economy that effectively uses natural and environmentally friendly resources. Solutions in this area are also promoted in tender proceedings in the area of public procurement. The LCA (Life Cycle Assessment) and LCC (Life Cycle Cost) analysis are indicated as the basis for decision-making by awarding...

  Publication

  - Key Engineering Materials - Year 2014

  This paper presents an enhanced approach, as it will be considered here that the ORC installation could be extra-heated with the bleed steam, a concept presented by the authors. In such way the efficiency of the bottoming cycle can be increased and an amount of electricity generated increases. A thermodynamic analysis and a comparative study of the cycle efficiency for a simplified steam cycle cooperating with ORC cycle will be...

  - Year 2012

  W pracy rozważono możliwość zastosowania układu ORC w skojarzeniu z ciepłownią lub elektrociepłownią celem podniesienia stopnia wykorzystania jednostki CHP podczas eksploatacji w skali roku. Połączenie układu ORC z zawodową jednostką CHP może wpłynąć na wzrost rocznej produkcji energii elektrycznej i jednoczsne zmniejszenie fluktuacji podczas pracy bloku energetycznego. Z jednej strony następuje konwersja energii cieplnej na elektryczną...
