MAN B&W 80-26MC/MC-C/ME/ME-C/ME-B/-GI-TII engines
Fig. 4.08.02a: List of capacities for L23/30H, 720/750 rpm, IMO Tier II
1)
Tolerance: + 10% for rating coolers, - 15% for heat recovery
2)
LT cooling water flow parallel through 1 stage charge air cooler and
through lube oil cooler and HT cooling water flow only through water
jacket and cylinder head, water temperature outlet engine regulated by
thermostat
3)
Basic values for layout of the coolers
4)
Under above mentioned reference conditions
5)
Tolerance: qu/- 5%, tempe/- 20°C
6)
Under below mentioned temperature at turbine outlet and pressure
according above mentioned reference conditions
7)
Tolerance of the pumps delivery capacities must be considered by the
manufactures
8)
To compensate for built on pumps, ambient condition, calorific value
and adequate circulations flow. The ISO fuel oil consumption is multi-
plied by 1.45.
