Section 5: DEFINITIVE DESIGNS FOR DIESEL-ELECTRIC GENERATING PLANTS
5.1
Definitive Diesel-Electric Generating Plants. The Navy has several
definitive designs and guide specifications for both prime duty and
standby/emergency duty stationary diesel-electric generating plants. Duty
types are defined defined Section 2. Application of each definitive design and
guide specification to various engine generator set sizes is provided in
-
Table 1 and definitive design inspection 1.
Rotational speed and Break Mean Effective Pressure (BMEP)limits are?
summarized in Table 7 for various unit generator sizes and duties.
