Abstract For Water Tube Boiler Temperature

Steam-Water Circulation in Boilers | SpringerLink

Abstract. Circulation refers here to the flow of water, steam, or their mixture around the steam—water circuit in a boiler. In early days of boilers, steam was generated in a large vessel. The vessel was heated from outside, which would create a convective current within the large body of water.

What is a Boiler? Different Types of Boiler -

The water is heated to its boiling temperature by the use of heat from the furnace. Due to the heating of water, it gets converted into high-pressure steam. The steam generated is passed through the steam turbines. As the high-pressure steam strikes the turbine, it rotates the turbine. Water Tube Boiler: In water tube boilers, the water is
