A boiler is a pressure vessel that generates steam or hot water by boiling water in an enclosed chamber. The heat required to boil the water is generated by burning a fuel source in the boiler furnace, which can be diesel, fossil fuel, coal, etc.
Purpose Of Boilers On Ships
When used on ships, the main purpose of the boiler is to generate steam, which can be further utilised for several heat transfer processes. Modern boilers now come integrated with a heat recovery system, which maximizes energy usage and increases overall efficiency.
To understand the usage of boilers on ships, it is essential to understand the broad classification of Marine boilers used on ships:
1. Main Boiler
2. Auxiliary Boiler
1. Main Boiler
The main boiler generates high-pressure steam for the ship’s propulsion. This propulsion is typically a steam turbine system that requires continuous steam input. Ships generally use heavy fuels, but with new stringent environmental regulations, they can also operate using Marine Gas Oil (MGO) or LNG fuel, which has high
