A fire-tube boiler differs from a water tube boiler, and is a type of boiler in which hot gases from a fire pass 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.
Working Principle of Water Tube Boiler . The working principle of water tube boiler is thermal siphoning (circulation of natural water). Basically, this type of boiler includes two drums namely steam, lower or mud drum. The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At
The discussion of different types of boilers, below, provides more detail on the designs of specific boiler systems. Types of Boilers Boilers are classified into different types based on their working pressure and temperature, fuel type, draft method, size and capacity, and whether they condense the water vapor in the combustion gases.
Boiler Types and Classifications. There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler."Boilers that operate higher than 15 psig are called "high-pressure" boilers.
Our two-pass, three-pass or four-pass Scotch Marine(Fire Tube) boilers are available in dryback, wetback, steam or hot water versions; from 15 to 800 hp with pressures to 300 psig. Hurst Scotch Marine boilers are rated to 81% minimum efficiency.
Fire tube boiler is one of the most basic types of boiler and the design is also very old. It was popular in 18 th century. It was mainly used for steam locomotive engines. Operation of Fire Tube Boiler. Operation of fire tube boiler is as simple as its construction. In fire tube boiler, the fuel is burnt inside a furnace.The hot gases produced in the furnace then passes through the fire tubes.
There are two common types of boilers: Fire-tube Boilers; Water-tube Boilers; Fire-Tube Boilers. A fire-tube boiler's principal elements include a cylindrical shell, a set of tubes, a feedwater channel line, and a combustion gas vent stack. The name fire tube is very picturesque. The fire, or hot flue gases from the stove, is led through a

As the water and steam both are in same vessel a fire tube boiler cannot produce steam at very high pressure. Generally it can produce maximum 17.5 kg/cm 2 and with a capacity of 9 Metric Ton of steam per hour. Types of Fire Tube Boiler. There are different types of fire tube boiler likewise, external furnace and internal furnace fire tube boiler.
used in these boilers are gases and liquids. The type of tube construction used in these three boilers affects the boiler construction. Boilers that use a tangent tube wall (see Figure 4) to define the combustion chamber and outer walls will require an outside, gas-tight, enclosure. Because the tubes will

Package boilers are generally shell type with fire tube design so as to achieve high heat transfer rates The packaged boiler is so called because it comes as a complete package. Once delivered to site, it requires only the steam, water pipe work, fuel supply and electrical connections to be made for it to become operational.
In fire-tube boilers, flue gases are inside of tubes, and water is in the shell around the tubes. Steam Applications. In steam applications, water quality is an important part of boiler selection. Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant
A fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water. The heat energy from the gases passes through the sides of the tubes by thermal conduction, heating the water and ultimately creating steam.
Before starting a steam boiler in wet lay-up, perform a bottom blowoff of the boiler to reduce the alkalinity (thus minimizing the chance of carryover). For all boilers, ensure all tags and locks are removed, and witness the system cycles for a minimum of three cycles.
Advantages and Disadvantages of Fire Tube Boiler 2016-07-20 17:49:36. Each steam boiler type has its advantages and disadvantage as well as with the type of fire tube boiler. 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.

A feedwater diffuser is provided on high pressure boilers. All water boilers are equipped with a dip tube at supply outlet and diffuser at return inlet.
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) 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
Efficiency of the combination tube boilers is studied by the direct and heat loss methods. It is seen that the combination tube boilers give optimum efficiency, even with the low grade fuels. From the heat balance sheets, it is observed that the dry flue gas loss is a major loss in the combination tube boilers.
A vertical tubeless is another type of boiler available that does not really fall into the firetube or watertube category. These boilers are generally used for high-pressure steam but are also offered in low pressure/hot water. They can either fire downward or fire with
The safe and efficient operation of boilers and domestic water heaters is essential for the smooth operation of most institutional and commercial facilities. Improvements in designs and control systems have made today's units safer and more efficient than ever.
Boilers therefore can be classified based on firing type, fuel used, construction type, circulation type, firing system design nature, and nature of steam application. Today's steam generating systems owe their dependability and safety to more than 125 years of experience in the design, fabrication, and operation of water tube boilers.
Water tube boilers can operate at pressures up to 5000 psig. Additionally, when used with steam circulating super-heaters, they are capable of reaching much higher temperatures than fire tube boilers. For these reasons, water tube boilers have become the most commonly used boiler type in the modern age.

Water tube or "water in tube" boilers in which the conditions are reversed with the water passing through the tubes and the hot gasses passing outside the tubes (see figure 2.3). These boilers can be of single- or multiple-drum type. These boilers can be built to any steam capacities and pressures, and have higher efficiencies than fire
Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure
