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

The 1712 boiler was assembled from riveted copper plates with a domed top made of lead in the first examples. Later boilers were made of small wrought iron plates riveted together.

The water within that water drum and the connecting pipes to the other two upper drums, are heated up and consequently steam bubbles are produced.

Modern boilers are made of alloy steel to withstand high pressures and extremely high temperatures. Most conventional steam boilers are classed as either fire-tube or watertube types. In the fire-tube type, the water surrounds the steel tubes through which hot gases from the furnace flow. The steam generated collects above the water level in a

All boilers have a radiant and a conviction sections, tubes around the furnace are called generation or riser tubes about a half of steam is generated in this area rest of the steam is produced in the convection section. Water inside the tubes become hot and due to natural circulation steam is collected and separated in the steam drum.

  • OverviewThe working principle of water tube boiler is thermal siphoning (circulation of natural water). Basically, this type of boiler includes two drums namely steam, lower or mud drum. The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At first, the water is supplied into the steam type drum with the help of a water pump. Whenever the fuel is …

Alfred Yarrow developed his boiler as a response to others that had already developed water-tube boilers. This was a long process based on theoretical experiment rather than evolution of practical boilers. Work began in 1877 and the first commercial boiler was not supplied until 10 years later, a torpedo boat of 1887.
