Fig. 4.07.02a: List of capacities for L21/31, 900 rpm, IMO Tier II
L21/31-Tll GenSet Data
1) LT cooling water flow first through LT stage charge air cooler, then
through lube oil cooler, water temperature outlet engine regulated by
mechanical thermostat
2) HT cooling water flow irst through water jacket and cylinder head, then
trough HT stage charge air cooler, water temperature outlet engine
regulated by mechanical thermostat
3) Tolerance: + 10% for rating coolers, - 15% for heat recovery
4) Basic values for layout of the coolers
5) under above mentioned reference conditions
6) Tolerance: qu/- 5%, tempe/- 20°C
7) under below mentioned temperature at turbine outlet and pressure
according above mentioned reference conditions
8) Tolerance of the pumps delivery capacities must be considered by the
manufactures
