Fire tube boilers are a lower cost alternative to water tube boilers and are often used for smaller industrial facilities with lower operating pressures. The main advantages of a fire tube boiler are its simple construction, compact size and the ability to easily meet rapid fluctuations in steam demand.
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 provide the most flexibility for heating because they can handle high pressure process loads, as well as heating water and air for low pressure applications through steam-to-water or steam-to-air heat exchangers.
The older fire-tube boiler design, in which the water surrounds the heat source and gases from combustion pass through tubes within the water space, is a much weaker structure and is rarely used for pressures above 2.4 MPa (350 psi).

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
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.
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.
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.
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.
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.
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.
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.
On both fire tube and water tube boiler any type of fuel can be used for providing the heat. Normal efficiency of the fire tube boiler is about 80 to 85 % but this can be increase or decrease by using different a accessories. Efficiency of the water tube boiler is more than that of fire tube and lies within the range of 85 to 90 %.
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.
