This article is to discuss about the various types of marine boilers that are being used or once used to drive the ships or to generate the steam. On the other hand we also discuss about the differences that water tube and smoke tube boiler have among them. Main idea is to make readers aware about the various types of boiler that are used on ships. So let’s read this article in detail.
Different types of marine boilers
Foster Wheeler boiler
Marine Radiant boiler
Read this interesting article on classification of marine boilers
Tangentially fired boiler
Composit Cochran boiler- Composite boilers are mostly sued on ships because when a ship is in port, the firing is through the burner. But when a ship is en route, then main engine exhaust is used to heat the water in order to generate the required steam.
What are Smoke type boilers?
What are water tube boilers?
Difference between Smoke and Water tube boilers
Smoke tube boilers are heavy in comparison to the water tube boilers.
Its efficiency is low and can only generate low or medium pressure steam.
Smoke tube boilers are having less efficient combustion.
Generally in smoke tube boilers, the threat of thermal stress is high because water circulation is poor.
It consumes more space and generation of steam takes longer time.
Furnace and shell of this type of boiler is sometime subjects to deformations and this may result in the hazardous event.
Tubes of this type of boiler are generally having the larger diameter and hence they are joined with the help of welding only.
Water is scarcity is not a problem in this type of boiler as tubes are always having covering of water and we can use any type of water in order to generate steam.
These types of boilers have light weight construction.
