Boiler is a necessary part of every ship, and it is used to generate steam. Different types of boilers are used on board ships, depending on the size and purpose of the vessel. In this article, we will discuss some of the most common types of boilers used on board ships and their applications.

The first type of boiler used on board ships is the water-tube boiler. This type of boiler is made up of a series of tubes that contain water and are heated by a firebox. It is usually used for propulsion and auxiliary systems, as well as for heating and cooling. This type of boiler is usually more efficient than other types, due to its ability to generate more steam with less fuel.

The second type of boiler used on board ships is the fire-tube boiler. This type of boiler is made up of a series of tubes that contain hot gases and are surrounded by water. It is used for propulsion, heating and cooling, and other auxiliary systems. It is usually less efficient than the water-tube boiler, but it is much easier to maintain and repair.

The third type of boiler used on board ships is the steam generator. This type of boiler is used to generate steam for propulsion and auxiliary systems. It is usually more efficient than the other types of boilers, and it is also easier to maintain and repair. This type of boiler is usually used for larger ships, as it is able to generate more steam with less fuel.

The fourth type of boiler used on board ships is the exhaust gas boiler. This type of boiler is used to generate steam from the exhaust gases of the engines. It is usually more efficient than the other types of boilers, and it is also easier to maintain and repair. This type of boiler is usually used for smaller ships, as it is able to generate more steam with less fuel.

The fifth type of boiler used on board ships is the combined cycle boiler. This type of boiler is made up of both a water-tube and a fire-tube boiler. It is used to generate both steam and hot water. This type of boiler is usually more efficient than the other types, and it is also easier to maintain and repair.

In conclusion, there are five main types of boilers used on board ships. Each type has its own advantages and disadvantages, and it is important to choose the right type of boiler for the vessel. All types of boilers must be regularly maintained and inspected to ensure that they are safe and efficient. Understanding the different types of boilers used on board ships can help you make the best decision for your vessel.
