05-06-2018· In Fire-tube boilers hot flue gases pass through tubes and water surrounds them. In Water-tube boilers water passes through tubes and hot flue gasses surround them. 2 These are operated at low pressures up to 20 bar.

Fire-tube boiler is those boiler in which the fire or hot gas is present inside the tubes and water surrounds these fire tubes. Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water.

23-04-2016· Fire Tube Boiler It is a boiler in which the hot flue gases is present inside the tubes and the water surrounds these tubes. As fire is present insides the tubes, hence it is called as fire tube boiler. The steam produced by these boilers have pressure of about 25 bar and that’s why they fall under the category of low pressure boilers.

19-03-2016· 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.

06-08-2014· Difference between Fire tube boiler and water tube boiler Structure. Both are shell and tube type of boiler, fire tube have hot gases inside the tube while water tube have water inside the tube and hot gases surrounding them. Steam pressure. Steam pressure limit of the fire tube boiler is lies between 20-30 bar and the pressure limit of the water tube boiler is much more than the fire tube …

The water in the tubes creates steam directly, instead of tubes heating water as is the case in a fire tube boiler. Water tube boilers are used more for industrial applications and less for heating purposes. A fire tube boiler transfers heat through tubes via thermal conduction, which then heats the water in the container and formulates steam.

13-06-2013· With firetube boilers, flue gases are directed through vertical or horizontal steel tubes that are surrounded by the water for heating, and typically go through two, three, or four passes, or changes in direction. In watertube boilers, the arrangement is reversed.

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. Here are a few key differences between the two:

18 rows· The main difference between fire tube and water tube boiler are, fire tube boiler are …

The distinction between fire tube boiler and water tube boiler should be possible on different focuses. These focuses incorporates sorts of liquid streams inside the cylinders, steam age rate, floor zone required for the steam age, transportation, proficiency, fluctuating burdens, working expense and so forth the learning of the distinction about these two heater is exceptionally critical.
