This part of the text deals with the major units of machinery in the 

 conventional steam turbine propulsion plant-a type of plant which is at 

 present widely used in naval ships. For the most part, the discussion is 

 concerned with geared-turbine drive; but some of the information is also 

 applicable to those few ships with turboelectric drive. The term "con- 

 ventional" is used here to indicate that the plants under discussion 

 utilize conventional boilers, rather than nuclear reactors, as the source 

 of heat for the generation of steam. 



Chapter 9 introduces the conventional steam turbine propulsion plant 

 by taking up the arrangement of propulsion machinery and the major 

 engineering piping systems found aboard conventional steam-driven ships. 

 Chapters 10 and 11 deal with propulsion boilers and their fittings and 

 controls. Chapter 12 describes propulsion steam turbines. Chapter 13 

 discusses the condensers and other heat transfer apparatus used in the 

 condensate and feed system of the conventional steam turbine propulsion 

 plant. 



As may be noted, the sequence of presentation follows the sequence 

 of the thermodynamic cycle. The boiler is the heat source , or high- 

 temperature region; the turbine is the engine in which the thermal 

 energy of the steam is converted into mechanical energy which drives 

 the ship; and the condenser is the heat receiver to which some heat 

 must always be rejected in order to allow the conversion of heat to work.
