Scotch Marine Boiler

The steam boilers for marine use that are tank-type or scotch are employed for marine operations specifically because of their compactness as well as their efficiency during operation and the ability to work with any kind of water. It doesn't require brickwork settings or external flues.

Scotch marine boiler a well-known boiler that was the first to have been put in a ship around 1862. It was to 1900, it was the only boiler of its kind on merchant ships or Navy vessels.

At the time, water tube boilers first began to be used, but for many years the Scotch marine was the most popular boiler. Since the development of high-pressure power stations, and water tubes, the boiler came to be necessary. But, there is many older American vessels that have Scotch boilers.

Principal Components of Scotch marine boilers are:

Furnaces-

The fuel used in the Scotch boiler is burnt in a steel cylindrical furnace that is located in the water chamber inside the boiler. There are a variety of furnaces. is contingent upon the dimensions of the boiler typically between three and four.

Combustion Chamber-

The furnace is opened to the combustion chamber, which is essentially an rectangular steel box that is set on its end, and is surrounded by water.

Inside the chamber of combustion, gasses that are not burned, released from the burning fuel inside the furnace combine with air to ignite.

Tubes-

The tubes are made from seamless drawn steel. The most common size is 3 1/4 inches in diameter outside that is how all boiler tubes are measured.

It is the Scotch marine boiler is 2-pass (or even) configuration of pipes running horizontally, allowing the heat within the tubes to move between the tubes. It also houses an internally fired furnace that has an enclosed combustion chamber that is cylindrical.

Staytubes-

A small percentage of tubes, which are scattered throughout the firetubes are also staytubes. They weigh more and are put into the tube sheets for added support to the tubes and heads.
