Boiler Accessories and their functions

The injector uses boiler steam or steam from another source to feed the water in the boiler. Injector works on Bernoulli theorem. It consists of two parts. One part contains a water cone and a steam cone. This part converts pressure into velocity and sends high-velocity mixer jet to the second part of the injector.

Marine Boilers - Marine Engineering Knowledge Part

What is the meaning of marine boilers ? 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. What is the boiler mounting ?

Introduction to Boiler water and Steam raising - N.E

2013-2-13 · As steam is produced, dissolved salts remain in the boiler and continue to concentrate. Some salts may be soluble in the bulk boiler water. However, the boiler water immediately at the tube surface is considerably hotter than the bulk boiler water. As steam bubbles form near the tube wall, the soluble salts remain with the boiler water.

Choosing The Right Boiler: Watertube vs. Firetube -

2  · Fuel is burned inside the furnace, which heats the water in the steam-generating tubes. The water then rises to the steam drum where saturated steam is drawn from the top of the drum. The watertube boiler has some relative advantages over the firetube boiler design, which are outlined below. Watertube boilers are safer by design and generally

Operation of water tube boilers explain

Water tube boilers are the most widely used boilers. These type has replaced many boilers, including the fire tube type, mainly because of the following reasons : The weight of the water tube boiler is much less than any type of boiler of equivalent size. Steam raising and steam generation process is much faster
