To detect a tube leak in a fire tube boiler, you can look for signs such as increased fuel consumption, reduced boiler efficiency, visible steam or water leakage from the tube, or unusual noises coming from the boiler. You may also conduct non-destructive testing methods like ultrasonic testing or using a thermal imaging camera to pinpoint the location of the leak. Regular inspection and maintenance are crucial to prevent and address tube leaks promptly.
Usually Alloy steel is used, copper and brass are also used as boiler tube materials
Sediment deposition is less in water tube boilers compared to fire tube boilers because water tube boilers have a higher water velocity that helps prevent sediment from settling on the tubes. Additionally, the design of water tube boilers allows for easier removal of any sediment that does accumulate.
"MTW" stands for "Minimum Tube Wall." It is a specification used in boiler tubing to indicate the minimum thickness of the tube wall required for safe and efficient operation of the boiler. Adhering to the MTW standard ensures that the boiler tubes can withstand the high pressure and temperature conditions within the boiler.
A hot spot on a boiler tube is an area where the temperature is significantly higher than the surrounding areas. It can be caused by various factors, such as localized heat transfer issues, improper water chemistry, or inadequate cooling. Hot spots can lead to tube failure and should be addressed promptly to prevent damage to the boiler.
The ligament is the section of metal between the holes in a tube sheet. A tube sheet is a portion of a boiler drum, or header perforated for the insertion of tubes. The tubes may be fire tubes (carries fire through water) or water tube (filled with water, surrounded by fire). That arrangement of tubes, with their retaining sheets, forms a more efficient means of transferring heat to water, and making more steam. It was also a stronger design, permitting operation at higher pressures than before.
The words are literal , a water tube boiler is water inside the tubes with hot gases surrounding them and a fire tube boiler are got gases within the tubes with water surrounding them.
there are two types of boilers water tube and fire tube. fire tube boilers are divided in to two categories vertical and horizontal. this according to the construction of fire tubes. it is said that vertical boilers are inefficient than horizontal boilers. The vertical boiler is small capacity, and horizontal boiler is higher capacity, well, the horizontal boiler have many types according the drums, there are single drums boiler, and double drums boiler, while, the single drums boiler have fire tube boiler and water and fire tube boiler, double drums boiler is usually water tube boiler.
the advantage is the design is complicated
In a fire tube boiler, the water surrounds a set of tubes through which the fire and the products of combustion travel (as opposed to a water tube boiler, in which the water travels through the tubes, and the fire surrounds the tubes).The HVAC Veteran
Fire tube and water tube. Steam Boiler and Water Boiler.
The difference between the two is that the Water tube boilers are safer and last much longer than the fire tube boiler. Their size is also larger and have a faster recovery time. However fire tube boilers have a low cost.

The answer is in the name. Boilers are made with a "tube - in - shell" construction, and the name implies what is in the tube. In a water tube boiler, the water circulates through the tubes, and the burner is usually under them. Most of the time, the "shell" of this style of boiler would not be watertight. A fire tube boiler has a watertight outer jacket with tubes through the center of it. The flame is shot through the tubes.
A simple vertical boiler is a type of fire-tube or water-tube boiler where the boiler barrel is oriented vertically instead of the more common horizontal orientation.
the maximum pressure and the capacity in the fire tube boiler are usually depends on the model design and specified by the manufacturers in the manufacturer manual.
The Cornish Boiler only has one fire tube compared to the Lancashire Boiler's two.
