Fire Tube Boiler Construction and Working Principle of Fire Tube Boiler. The construction of a water tube boiler can be equipped with cylindrical shell, vertical, firebox in the base, space for water in the center segment, and space for steam in the higher segment. A fire-grate is located at the fire-box base as well as coal is fired-up on the
Jun 05, 2018· Comparison between Fire Tube and Water Tube Boiler can be done in 14 aspects. Those aspects are operating pressure, passage of material type in tubes, rate of steam generation, handling of load fluctuation, floor area requirement, efficiency, operator skills, design, maintenance cost are listed below in the tabular form.
Apr 23, 2018· The water-tube boiler has some special advantage that the fire tube boiler doesn’t have. Before we start let’s know about the working principle of a water tube boiler and it will help you to understand its advantage and disadvantages clearly.
Fire Tube BoilersAdvantages of fire tube boilers: - More residual heat in the. water to allow for load swings - Simpler control systems due to. larger volumes of water in shell - Water quality doesn't change as

Advantages and disadvantages compare to what? Let’s assume it is compared with fire tube and smoke boilers: Water Tube Boiler: Advantages• * Water circulates in the tubes and fuel is burned inside the furnace. * Low water content * Quicker steam r
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
Jun 23, 2015· By now, we have types of fire tube boilers, such as WNS series gas oil fire tube boiler, DZL series packaged fire-water tube boiler, etc. Advantages of Fire Tube Boiler 1) Compact in construction. 2) Fluctuation of steam demand can be met easily. 3) Cheaper than water tube boiler.
Advantages and Disadvantages of Water Tube Boilers over Fire Tube Boilers: Advantages: 1. Steam can be raised more quickly: In water tube boilers, the ratio of water content to the steam capacity is comparatively less than the fire tube boiler. Hence water tube boilers can quickly generate steam at the required pressure than the fire tube boiler. 2. Steam at higher pressures can be produced
Fire-tube boiler: Fire-tube boiler is those boiler in which the fire or hot gas is present inside the tubes and water surrounds these fire tubes. Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water.
Mar 19, 2016· Fire tube boiler have lower rate of steam production compare to water tube. It has higher rate of steam production. These boilers are almost internally fired. Furnace is placed at the one end of fire tube. These boilers are generally externally fired. It is suitable for the production work like sugar mill, textile industries.
The following are advantages and disadvantages if the owner of power plant choose fire tube boiler as his boiler. Advantages of fire tube boiler: 1. The water is supplied in shell and outside tubes while hot gas is supplied inside tubes so the water volume can not be shaken easily when the fire tube boiler is running. 2. Fire tube boiler is so
Mar 26, 2016· From the perspective of heat transfer: A boiler nothing but a heat exchanger wherein a hot fluid (flue gas) supplies heat to the cold fluid (water) such that it evaporates. The major factor that determines the heat transferred is the heat transfe
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
Feb 22, 2018· The water tube boiler’s furnace area can be easily altered to meet the fuel requirements. Demerits of Water Tube Boiler over Fire Tube Boiler: It is less suitable for impure and sedimentary water, as a small deposit of scale may cause the overheating and bursting of the tube.
Advantages of fire tube boiler: 1. The water is supplied in shell and outside tubes while hot gas is supplied inside tubes so the water volume can not be shaken easily when the fire tube boiler is running. 2. Fire tube boiler is so easy to use, operate, clean and maintain 3. Fire tube boiler can be used in small scale industries. 4. Fire tube
Advantages and Disadvantages of Water Tube Boilers 11-04 08:57:36. There are two main boiler types that people can choose from for their specific application: water tube boilers and fire tube boilers.Of the two, water tube boilers contain wider range than fire tube boilers and they are …
Boiler: A Boiler is a closed vessel in which steams are generated (Water to steam) with the help of coal-burning or other fuel substances.. Basically, There are two types of Boiler. Fire Tube Boiler; Water Tube Boiler; Fire Tube Boiler: The fire-tube boiler is the boiler in which fire (hot flue gases) is inside the tube and water is surrounded by them.. Some example of Fire Tube Boiler are:
Fire-tube boiler: This is a boiler in which the fire or hot gas is present inside the tubes and water surrounds these fire tubes.; Since fire is inside the tubes and hence it is named as fire tube boiler.The heat from the hot gases is conducted through the walls of the tube to the water.
