Boiler Alarms And Trips | 5 Common Boiler Safety Devices

Boilers fall into two categories: water-tube and fire-tube ones, according to which substance passes through the tube and which flows round the outside. They are used to provide steam for propulsion or for various ship services. A boiler is used to heat feed water in order to produce steam.

Boiler Mountings And Their Function - Complete List

The D-type boiler has been installed in US Navy ships since 1950. Whether 600 psi or 1200 psi, D-type boiler construction is basically the same with a few exceptions, such as number of fuel oil burners and overall size and volume. Fuel oil burners are located on the boiler front and extend into the furnace to provide a means of firing the boiler.

Alfa Laval - Aalborg D

Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.
