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, heating the water and ultimately creating steam..
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes
If these minerals are present in the boiler's water supply, it can lead to hard scale forming on the surface of the tubes, which has the potential to cause the water to overheat and ultimately the tubes to fail. The efficiency of a boiler can also be negatively affected by hard water. If the presence of calcium and magnesium causes hard
some advantages are gained over the low pressure steam heating systems previously used. In other cases, special forced circulation boilers have been designed, which consist of many rows of tubes without a steam drum. In another type, heat is supplied by steam from a standard type of boiler which heats the water in a direct contact heater. This

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
Water Boilers Main Features Advantages Major advantages of water tube boiler systems include: These boiler systems contain very small quantity of water hence; their response is fairly quick towards variations in load and heat supply. The small diameter tubes and steam drum mean that much higher steam pressures can be tolerated, and up to 160
other advantages of replacing with the Solution . . . - Lo/Hi/Lo Temperature Control - Since full boiler capacity is only needed usually 20% of the heating season this control only turns the boiler on full fire when full capacity is needed. Most cast iron boilers are on/off loosing valuable heating dollars and eliminates short cycling.

Boiler tube failures, especially in coal-fired power plants, continue to be the major cause of boiler forced outages. However, if a tube leak is detected early more severe damage to surrounding
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
A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress.
The biggest disadvantage of the Smithies boiler is the limited water capacity of its inner barrel as compared to other boiler types with similar external dimensions. Vertical Type The vertical boiler is a simple type which consists of a firebox at the bottom and a copper barrel with a smoke tube.
Therefore, water treatment is always required in the make-up water of a boiler. Water treatment of make-up water will depend on the source of water and boiler manufacturer requirements: suspended solids removal, dissolved solids removal, softening, pH adjustment, dosing of biocides for bacterial control, dosing of anticorrosion agents.
A parallel evaluation of fire tube waste heat recovery boiler is the locomotive boiler with the furnace surrounded by a heat transfer area and a heat transfer area added by using horizontal tubes.

In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Because tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (3,000 psi, sometimes higher) are required.
We briefly discuss about Water tube boiler parts and functions. D type water tube boiler. In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt.
If water or steam hits a clean section of a boiler tube, it can cause tube erosion over time. Cold water hitting a hot tube can also cause the tube to contract, leading to tube damage and a
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
The fire tube boilers may have single or multi tubes. Lancashire boiler is a fire tube boiler with a single tube in which hot gases move. Cochran boiler is a fire tube boiler called as multi tube boiler because it has large number of fire tubes. (v) Stationary and Portable Boilers:
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.
An electric boiler uses electricity rather than gas to generate hot water. Just like a gas boiler, it will heat up the water that warms the radiators and water you use in your home. Electric boilers can be used at off-grid properties, or where a gas supply is not available or not wanted. Advantages Of Electric Boilers
In a water tube steam boiler water flows through the pipes and the flue gasses pass around the pipes. Water tube steam boilers are applied above 32 bar and with difficult fuels. This type of boiler can be cleaned automatically and with ease. advantages of fire tube boiler | Steam Boiler Producer. Fire-tube boiler Wikipedia.
An increase in temperature results in an increase in electrical conductivity. For boiler water, the conductivity increases at the rate of approximately 2% (of the value at 25°C) for every 1°C increase in temperature. This can be written as: Example 3.12.3. A boiler water sample has an unneutralised conductivity of 5 000 μS/cm at 25°C.
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.. Advantages of Water Tube Boiler. There are many advantages of water tube boiler due to which
First of all Water Tube Boiler and Fire Tube Boiler are completely opposite to its structural designs. In Water Tube Boiler water will be heated inside the Boiler Tube and heat will pass around the Tubes. Generally, heat passes from the boiler Furnace or Combustion Chamber to around the Boiler Tube.
