• The analysis of turbine propulsion systems in nuclear submarines

  Publikacja

  • M. Piwowarski

  - Key Engineering Materials - Rok 2014

  The article systematises submarines, which are presently in service, according to their propulsion types (both conventional and nuclear), power output, and submersion depth. Contemporary types of propulsion systems installed and used in submarines are discussed. Calculations were performed for the PWR (Pressurized Water Reactor) type nuclear propulsion system and the supercritical turbine propulsion system (supercritical reactor...

  - Polish Maritime Research - Rok 2022

  This article provides a review of the possibility of using different types of reactors to power ships. The analyses were carried out for three different large vessels: a container ship, a liquid gas carrier and a bulk carrier. A novelty of this work is the analysis of the proposal to adapt marine power plants to ecological requirements in shipping by replacing the conventional propulsion system based on internal combustion engines...

• Logistical Aspects of Energy Conversion Efficiency in Marine Steam Power Plants in Off-Design Conditions

  Publikacja

  • T. Kowalczyk
  • J. Badur

  - Logistyka - Rok 2014

  The paper presents logistical aspects of energy conversion efficiency in off-design conditions. The main part of the article is based on results of thermodynamic calculation for large propulsion steam turbine under partial loads. Calculations are made on extended mathematical model of two proposed steam turbine thermodynamic cycles using Stodola’s cone law. The conclusion based on calculation re-sults contains importance of off-design...
