A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low …Get Price
Understanding the operational design differences. Firetube boilers are available in either dryback or wetback design. They are identified by the type of reversal (turnaround) chamber, or posterior portion of the combustion chamber, through which flue gasses travel through the furnace to second-pass tubes to heat water within the boiler.Get Price
A major difference between Firetube and Watertube boilers is that the Firetube boiler has a much larger water and steam content for any given capacity. This is inherent in the design of the boiler, and the reason for most of the differences between boiler types. This large reservoir of water and steam makes the Firetube steam pressure and water Get Price
Feb 24, 2012 · As the water and steam both are in same vessel a fire tube boiler cannot produce steam at very high pressure..

CONCLUSION • The main difference between fire-tube and water-tube boiler are, fire-tube boiler is internally fired and water-tube boiler are externally fired boiler. Hot gases flow inside the tube and water surrounds them in the fire-tube boiler whereas, in the water-tube, water flows inside the tube and hot gases surround them.Get Price
Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.Get Price
These have higher efficiencies than fire tube boilers. Depending on layout boilers can also be classified as: 1. Longitudinal drum boiler. The feedwater is feed in drum. The drum is placed above the heat source. The cooler water goes to the inclined tubes and the water is heating eventually in the hot tubes.Get Price
A fire-tube boiler is a boiler in which gases of combustion flow through tubes surrounded by water. A vertical fire-tube boiler consists of a cylindrical shell with an enclosed firebox at the bottom. Tubes extend from the firebox (aka crown sheet) to the upper tube sheet, where they are rolled and beaded over. vertical fire-tube boiler: 6 to 75 bhpGet Price
