Role Of Compressed Air In Engine
Do you know how diesel engines are started in ships?
Equivalent in size to a four-story building, the main propulsion engine is started with the help of compressed air at a pressure of 30 bar.
Learn more about how a ship gets its compressed air supply from.
Why compressed air? We discussed diesel engine starting problems in our previous article and saw how various methods are used to overcome this problem.
We also saw how a marine engine is different due to its size and location, and that compressed air is the solution to starting the diesel engine.
As you know that a ship is a mobile power plant or a moving mini-city. It has all facilities, sometimes better than what we find ashore.
These moving giants have a pre-designed and erected compressed air system, which facilitates many activities onboard a ship.
There are mostly 4 to 8 and sometimes 10 air compressors found onboard. These Air compressors take suction from the engine room atmosphere which is already under a slight positive pressure.
These air compressors compress the air in stages and fill up the huge air bottles, which acts as accumulator. The air compressors compress usually upto 30 bar and keep the air bottles filled up all the time.
The number of air bottles and its volume(capacity) depends on the power (size) of the main propulsion engine. These Air compressors are of varying capacity and used as per the requirement onboard.
