STARTING SYSTEM
Fig. shows a starting system for a large two-stroke engine.
Clean, dry, compressed air at starting pressure (30 bar) is stored and supplied to the
system from air receivers (1).
The main starting valve (2) is interposed in the starting air main pipe and operated
by a pneumatic actuator. Furthermore, a non-return valve (3) is incorporated,
which prevents blowback in the event of excessive pressure in the starting air line.
