▶️Introduction
Fire tube boilers are used for many industrial processes to generator steam. They are one of the two common boiler designs commonly employed today, the other design being the water tube boiler. The boiler shown in this video is a three pass boiler, as the gasses pass three times through the boiler shell.
How Fire Tube Boilers Work
Fuel is fed by a burner into a corrugated furnace along with air. The air and fuel mix and a source of ignition is applied in order to start combustion. The heat from the flame and exhaust gases is passed to the corrugated furnace, then to the water due to thermal conduction.
The exhaust gases then pass through a reversal chamber, the second pass of tubes, the third pass of tubes, then finally through a smoke box and out of the chimney. The furnace and tubes allow the heat generated by combustion to be transferred to the water in the shell. As the water in the shell is heated, it begins to turn to steam.
Fire tube boilers rely upon on relatively few parts, these parts include:
* Shell – fired pressure vessel.
* Burner – used for combustion.
* Corrugated Furnace – where combustion occurs.
* Tubes – used to direct exhaust gasses through the shell.
* Tube Sheets – used to hold the tubes in position.
* Reversal Chamber – gasses are reversed in this space and sent back in the opposite direction.
* Cover – retains insulation which increases the thermal efficiency of the boiler.
* Smoke Box – located where exhaust gasses exit the final tube pass, but before the chimney.

This is the most fantastic video I ever saw, thank you so much, neat explanation, incredible presentation. I Like It.
-
Simply, the best tool for transferring this type of knowledge. When you couple it with the excellent narration, you will see what a powerful, practical teaching tool it is.
-
Ever since I stepped my feet in engineering class, for the first time I've fully understood everything 100%, I feel like I owe you fees buddy, thanks alot
-
it is impressive how easily could the working principle of industrial boilers be explained with some quality visual representation like this one. Wish engineering schools learnt that THIS is the way. Great video.
-
Brilliant explanation! Having it disected in such a manner makes it exceptionally digestible. Thank you so much!
-
Incredible explanation along with 3d model. Showing every single part of the fire tube boiler force me to positive comment on your work. Try your best to explain various engineering equipment, there use and working principle.
-
An explanation of how a natural gas valve works inside a furnace or water heater would be interesting. I worked as a tool and die maker for a gas valve manufacturer for a number of years and always thought it was fascinating how they could have a fail safe operation utilizing thermocouples and micro electromagnetic actuators.
-
Great Tutorial. Your community should really be bigger than what it is presently. It should be in millions. Thank you
-
your videos are the best thing i found from the internet. thank you so much.
-
Great video with fantastic presentation! This helped me to understand the fire tube boiler within 15 minutes.
-
Very simply explained the structure, construction and working of a fire tube boiler. Would love to see videos on how to descale smoke tubes and to prevent it.
-
Great video! I am a chemical engineer student, and this content helped me so much to learn how boilers works.
-
Great work John!! Thank you so much from Brazil!!Your explanation allowed me to understand this system so much better ,God bless you!!
-
Some of the best instructional videos I ever seen.
-
Greetings from Ratman from Indonesia, thank you for sharing the knowledge of very good and successful steam boiler design for you
-
dude, you wonder that if I enjoyed the video; I say hats off. Appreciated 👏
-
This is a very deep video into the fire tube. Helpful, thank you.
-
Thank you sir! A 3rd year Mech engineering student here! Great video
-
It could never be explained better than this. Thanks alot. Please also explain about the other components of the boilers too
