Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam.

Mar 19, 2016· The boiler is divided into two main types. One is known as fire tube boiler and the other one is known as water tube boiler. These boilers is largely used in power development and other industrial like sugar industries, cotton industries etc. for steam generation.

In water-tube boilers, the fluid with the higher density flows through the tubes and the fluid of lower density flows through a larger diameter external to the tubes (combustion chamber), ultimately resulting in water-tube boilers having higher overall heat transfer coefficient when compared to a fire-tube condensing boiler of the same size and material.

Water tube boilers blow fire tube boilers away in regards to efficiency. Water tube boilers require far less water to function, and at the same time, they also have a higher rate of steam generation than fire tube boilers. This helps to reduce the amount of water and fuel necessary to make a water tube boiler run compared to the alternative option.

In the fire tube boiler hot flue gases flow inside the boiler and water flow surrounded the tube. In the water tube boiler flue gases flow outside the tube and water go through inside the tube. 2 Fire tube boilers are low pressure or medium pressure boiler.

Fire Tube Boiler generates less steam than Water Tube Boiler. Some experiments found that a Fire Tube Boiler can generate 18000 pounds (8164 Kg) steam per hour. When this Boiler was invented at that time it was a popular boiler for a different sector.

May 04, 2017· A water tube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In Fire-tube boilers hot flue gases pass through tubes and water surrounds them.

The main differences between the fire tube and the water tube boiler are the hot gases flow inside the tube and water surround them in the fire tube boiler whereas, In the water tube, water flows inside the tube and Hot gases surround them. Before moving to further detailed explanation lets have some overview of Fire tube and water tube boiler.

In a watertube boiler, the heating element acts directly on tubes filled with water, which run through the furnace casing, to produce the needed steam or super-hot water. In a firetube boiler, the heating element produces hot water through a more indirect mechanism.
