· What is the meaning of ? Boiler is a pressure vessel used on ships in which the water is heated to evaporate and generate the steam and the unit is so arranged that the generated steam accumulated in it The two main types are water tube and fire tube
A Scotch steam consists of a steam drum and one to four fire-tubes in which furnaces heats the A water-tube is a steam generator consisting of a steam drum and water-drums and tubes which are exposed to the heat of a furnace and arranged so as to promote rapid water circulation in the steam-boiler
· What is a? A boiler is defined as "a closed vessel in which water or other liquid is heated steam or vapor is generated steam is superheated or any combination thereof under pressure or vacuum for use external to itself by the direct application of energy from the combustion of fuels from electricity or nuclear energy"
are of two types namely the water tube and the fire tube The water tube type is used for high-pressure high-temperature high-capacity applications The Main design depends on its application ie for motor ships a small fire tube would be satisfactory
play an integral part in the operation of a ship Proper maintenance of these boilers is required for their smooth working and thus its important to understand their working Find out the science behind the water circulation on ships
· used in ships today are mostly for auxiliary purposes in vessels that run on diesel engines or diesel electric propulsion In case of ships using steam turbines (mostly found in high speed vessels used by navies) are a part of the main propulsion system However in this article we will focus on auxiliary ie used for running auxiliary systems in a ship
· Composit Cochran Composite 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 8) Thimble tube 9) Sunrod Boiler
