The fire tube boiler is a kind of industrial boiler that the flue gas generated after fuel combustion flows through the fire drum or flue pipe to heat the water, steam or steam-water mixture outside the fire drum or flue pipe. It is also called shell type boiler. Advantages: 1. It has simple structure, easy operation and convenient maintenance. 2.
Dec 07, 2016 · Fire Tube Boilers. They work by circulating hot gas through tubes, which in turn run through a water tank. The water is heated and eventually turns into steam, which is then used to generate energy. Fire tube boiler often have extensive maintenance requirements and are best suited for applications with lower pressures.
Water tube boiler. Contrary to smoke tube boilers, water tube boilers are that in which water circulates in tubes. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. This boilers include π type water tube boiler, some waste heat recovery boiler and D type water tube boiler.

Water-tube boiler is the boiler in which the water is present inside the tubes and fire or hot gases surrounds these fire tubes. Fire-tube boiler is the boiler in which the fire or hot gas is present inside the tubes and water surrounds these fire tubes.
Oct 28, 2014 · Steam Boilers OR Steam Generators. The water in these portions of the water tubes gets evaporated. The water and the steam mixture from this portion of the water tubes ascend through the uptake headers and reach the boiler drum. The steam from the steam space in the boiler drum is led into the branches of T-tube,
PTEC Equipment Boiler. • Scale- produced on inside of tube walls by dissolved solids. This could potentially result in overheat and rupture. • Soot buildup happens when there is too rich or burning a liquid fuel. • If loss of water flow occurs from pumps and the tubes go dry they will overheat quickly and may rupture causing a release
With less water volume, a watertube boiler has the ability to follow load swings more precisely and generally has better turndown than a firetube boiler. The rule of thumb is that if you have a very constant and steady load that doesn’t change often, then a firetube boiler will work well for you.
Clarity’s Water Treatment blog is dedicated to topics having to do with the water treatment industry. We cover popular water treatment topics that include boiler water, cooling water, and waste water treatment; as well as related topics like odor control, smart release technology, cooling tower cleaning, legionella remediation and
You can expect an operating pressure of between 30 to 125 psig from a high-temperature hot water boiler. Steam boilers are used for high or low pressure system requirements Steam boilers are best suited to applications that require high or low pressure, though some low-pressure units can be used for heat.
Difference Between Fire Tube Boiler and Water Tube Boiler Fire Tube Boiler. It is a boiler in which the hot flue gases is present inside the tubes and the water surrounds these tubes. As fire is present insides the tubes, hence it is called as fire tube boiler.
Comparison between Fire Tube and Water Tube Boiler can be done in aspects like efficiency, pressure operation, floor area, transportation, What is difference between water tube boiler and fire tube boiler Water Tube Boiler: Water circulates in tubes and heated externally by hot gases.
Jul 07, 2019 · The examples of the fire tube boiler are the simple vertical, Cochran, Lancashire, Cornish, Locomotive, Scotch marine, and Velcon boiler. Water-tube boiler: Water-tube boiler is those boiler in which the water is present inside the tubes and fire or hot gases surrounds these fire tubes.
May 05, 2017 · The main difference between fire-tube boiler and water-tube boiler is that fire-tube boiler develops heating surface inside the drum while water-tube boiler develops heating surface outside the drum. That is, fire (flue gas) is in the tube of fire tube boiler and water is in the tube of water tube boiler.
Water tubes. Fire-tube boilers sometimes have water-tubes as well, to increase the heating surface. A Cornish boiler may have several water-tubes across the diameter of the flue (this is common in steam launches). A locomotive boiler with a wide firebox may have arch tubes or thermic syphons.
Wetback Firetube Boilers. The surrounding water absorbs burner heat, helping improve operating efficiency as heat from combustion goes directly into evenly heating water instead of refractory. The wet back boiler design uses separate tube sheets between tube passes which can be more forgiving with load changes.
Apr 17, 2015 · The difference between water tube boiler and fire tube boiler is from the boiler structure, Water tube boiler is which the have lots of tubes in boilers, the water go through from tubes. Fire tube as its name implies , the fire gas go through inside of pipes.
The table below gives a brief comparison of Water Tube and Smoke Tube Boilers-comparison of water tube and smoke tube boilers
There are also flexible water tube systems. Fire tube: where the combustion gases and furnace flame are inside tubes located in a cylindrical vessel that holds the water and steam. Electrical: where electricity is the main energy source to heat the water, eliminating the need for combustion components inside the boiler or flue stacks to vent harmful exhaust.
The water flows through the smaller diameter boiler tubes while the combustion gases travel around them to transfer heat to the water. The boiler tubes in the watertube design carry the heated water inside the tubes between the lower drum (mud drum) and upper drums (steam drum), with the generated steam accumulating in the upper drum.

Water tube boilers can generate steam upto a pressure of 225 bar. 2. The rate of steam generation is more (upto 45000 kg/hr). 3. It can produce steam upto a maximum temperature of . Chat Online
Aug 22, 2018 · A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water.
Apr 23, 2016 · Fire tube boiler. Water tube boiler. 1. In this boiler the hot flue gases is present inside the tubes and water surrounds them: The water is present inside the tubes and the hot flue gases surrounds them: 2. They are low pressure boilers. The operating pressure is about 25 bar. They are high pressure boilers and the operating pressure is about 165 bar. 3.
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 and produce steam.
The output with the resistance is between 12 and 3,375 kW. The electrode boiler has a higher capacity, ranging from 2 to 65 MW. These boilers are used in a variety of applications since they are available for both high- and low-pressure steam and hot water.
Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.
In general, industrial boilers can be classified into two types, one is water tube boiler and the other is fire tube boiler. This article will introduce you the differences between water tube boiler and fire tube boiler from the following aspects. Design. Water tube boiler and fire tube boiler are essentially opposite in design. In a water tube boiler, water travels through tubes which are surrounded by the by-products of combustion, or flue gas.
The efficiency of water tube boiler is more compared to fire tube boiler. Water tube boiler is preferred for high pressure and high output. However, water tube boilers have a high risk of explosion or bursting compared to fire tube boilers and require more skilled supervision.
Thermal Efficiency Thermal efficiency is a measure of the effectiveness of the heat exchanger of the boiler. It measures the ability of the exchanger to transfer heat from the combustion process to the water or steam in the boiler.
Nov 24, 2016 · The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water flows from the shell and in water tube boiler, water flows from the tubes and the flue gases from the shell or passes over the tubes. Water Tube boiler has more advantage due to main following differences.
