The more efficient fire tube boiler has many tubes of small diameter passing through the water space of shell. Retarders are often fitted in these tubes, which increase the stay time of flue gases, this increasing the heating surface through which (fuels energy) heat is transfer to the water.

24-11-2016· Fire tube boiler consists of a vertical, cylindrical shell, equipped with a fire box in the bottom, water space in the middle portion and steam space in the upper portion. The fire grate is placed at the bottom of the fire box and coal is fired at the fire box.

The first quality of a boiler material that comes to mind is ductility - you want a material that will withstand many,many heating and cooling cycles, with out fatiguing and cracking. Strength is almost secondary - the strength of a boiler is in its structure. Up to about 5 1/2 - 6" diameter and 100 PSI copper has many advantages,above that,low carbon steel is the material of choice. I worked as a …

In water-tube boilers, the fluid with the higher density flows through the tubes and the fluid of lower density flows through a larger diameter external to the tubes (combustion chamber), ultimately resulting in water-tube boilers having higher overall heat transfer coefficient when compared to a fire-tube condensing boiler of the same size and material.

The Fire tube boiler is intended for transmitting hot-gases using heat source as well as cycle. These gases flow through pipes with a water-filled drum. This procedure efficiently transmits the heat from the hot gas to the water, which efficiently produces steam. The main features of fire tube boilers include a simple design, easy to operate as well as the low cost to purchase. These boilers are extremely …
