The heat from the hot gases transfers through the walls of the tubes and heats the water. In a water-tube boiler, the water is in the tubes while the fire is external to the tubes. The hot flue gases pass around and between the tubes, heating the water and then out the boiler vent.
The difference between fire tube boiler and water tube boiler can be done on various points. These points includes types of fluid flows within the tubes, steam generation rate, floor area required for the steam generation, transportation, efficiency, fluctuating loads, operating cost etc. the knowledge of the difference about these two boiler
Dec 02, 2016· The scotch fire tube boiler design is most commonly referred to as the scotch marine boiler. With this design, the furnace is a big diameter tube located inside of the boiler. The furnace and boiler are circumferenced by water. Some of the larger, older scotch boilers would have two or …
The main difference between fire tube and water tube boiler are, fire tube boiler are internally fired and water tube boiler are externally fired boiler. This is the most comprehensive guide on comparison or differences Between Fire Tube Boiler and Water Tube Boiler.
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.
In water-tube boiler, water circulates in a definite direction whereas in fire-tube boiler, water doesn’t circulate in a definite direction. A water-tube boiler is complex in design, difficult to install and has high maintenance cost. On the contrary, fire-tube boiler is simple in design, easy to install and has a low maintenance cost.
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.
What is difference between water tube boiler and fire . Water Tube Boiler: * Water circulates in tubes and heated externally by hot gases. Fuel is burned inside the furnace. i.e (hot gases- outside the tubes and water- inside the tubes). * Operating pressure = upto 100 bar * …
May 02, 2020· In a fire tube boiler, hot gas passes through the pipes and boiler feed water is inside the shell to be converted into steam. Fire tube boilers are usually used for relatively small steam capacities with low to moderate steam pressures.
Mar 04, 2020· A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are…
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.
Fire tubes are large and not easy for transporting whereas, in a water tube boiler, it is not an issue. The efficiency of fire tubers are up t0 75% whereas in water tube boiler is up to 90% The flow of direction in fire tube is not in an exact direction whereas, in water tube, it flows in an exact direction.
May 04, 2017· 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.
Apr 23, 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 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.
