Natural Draft Only
The first example is of the most basic ventilation system, the Natural Draft. In this type of system, the main engines pull air through the Mist Eliminators which are mounted in plenum boxes just inside the hull openings. As the combustion air is exhausted it removes heat from the space and no fans are used. This type of system is typically used on small boats, with very small engine spaces.
    ADVANTAGES:
  • Simple
  • Inexpensive
  • Lightweight
  • No electrical load

    DISADVANTAGES:
  • High temperatures at low RPM
  • No control of temperature
  • No electrical load
  • Large openings and Mist Eliminators are needed as engine size increases to provide an acceptable pressure drop for proper engine operation
