Steam and Gas Power System


  • Introduction: comparison of marine propulsion engines: motors, steam turbines, gas turbines,
  • Steam power cycles: improvement of circular processes, regenerative heating of the feed water, intermediate overheating of steam, continuity equation, gas and steam flow, nozzles.
  • Steam boilers and steam generators:
    • their development and division and properties, specific requirements of ship steam boilers,
    • Thermal balance of the boiler, heat loss and efficiency,
    • Air for combustion and exhaust gases,
    • Circulation of boiler water,
    • Fuel system,
    • Feed water system,
    • Materials for the production of the pressure part of the steam boiler and the regulations,
    • Thermal extensions and compensation,
    • Steam boiler control,
    • Equipment and protection of the steam boiler,
    • Operation and maintenance of the steam boiler,

Propulsive characteristics of diesel engines, steam and gas turbines, including speed, output and fuel consumption.




Goals and competencies

The student learns the elements of the ship's steam turbine plant and the gas turbine plant and processes that take place in individual components (heat transfer, combustion, evaporation, condensation ...). In addition to this, it also learns the components, the corresponding measurement technique and the procedures for controlling the operation and monitoring of individual parts, of total facilities under conditions of normal operation or accidental operation, as prescribed by the STCW Convention. The subject matter also covers the influence of turbine plants on the environment, the reduction or even the prevention of this effect during normal operation.


Special features:

Implementation of the learning content in accordance with the STCW Convention and recommendations in the IMO Model Course: 7.02 - Chief Engineer Officer and Second Engineer Officer
