Boilers can be broadly classified as shell tube and water tube boilers. Shell and tube boilers. Shell and tube boilers are also referred to as fire tube or smoke tube boilers. Fire tube boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates.
Mar 10, 2018 · Fire tube boilers fire tube boilers are basically boilers in which boiler tube contains fire or hot gases. In most of the plants these boilers are installed at the downstream of furnace so flue gases of furnace or or in case of hydrogen plant gases from the reformer passed through a fire tube boiler which generates steam.

Electric boilers can use electric resistance heating coils immersed in water and are normally very low-capacity units. Other types of electric boilers are electrode-type units that generate saturated steam by conducting current through the water itself. Boiler water conductivity must be monitored and controlled.
Boiler Types - Fire Tube Boilers. Firetube boilers confine the combustion process and gases in tubes, and water circulates these tubes. Some fire tube boilers have turbulators inside of the tubes to cause turbulence of the flue gases. That increases the heat absorption into the water, which makes the boiler more efficient.
Oct 26, 2017 · Meaning if the pressure drops on a fire tube boiler, it takes longer to come back up than on a similarly rated water tube boiler. Fire tube boilers typically have lower operating and maintenance costs, have easier access to the fire and water sides for inspections, and its much easier to replace tubes on a fire tube than a water tube.

Nov 25, 2015 · About Locomotive boilers : • Locomotive boiler is a horizontal fire tube type mobile boiler. The main requirement of this boiler is that it should produce steam at a very high rate. Therefore, this boiler requires a large amount of heating surface and large grate area to burn coal at a rapid rate.
Oct 26, 2017 · For residential and commercial/industrial purposes, there are 2 types of boilers. The most common is the fire tube design. This would include the common sectional type boiler seen in most residential applications. The fuel is burned, and the hot gases pass through a series of flue passages or tubes that are generally steel.
NOTE: Babcock and Wilcox boilers use solid or gaseous fuel. Volex boilers use oil fuel. According to the pressure of the boiler: High-pressure boiler; Medium-pressure boiler; Low-pressure boiler; High-pressure boiler: The pressure of the boiler above 80 bar. Medium-pressure boiler: It has a working pressure of steam from 20 bar to 80 bar. It is used for power generation or process heating.

Jul 02, 2016 · Disadvantages of fire tube boiler: From the furnace combustion side, required time to fill water is longer than to increase temperature and pressure. The efficiency of heat transfer (heat transfer efficiency) is bad enough because of the heat exchanger does not use thermal radiation.
Dec 02, 2016 · Multi-pass boilers are an extremely common option. These boilers are typically found in colleges, universities, or areas where the system is used to produce steam for space heating or use to create hot water. 3. Scotch Fire Tube Boiler Design. The scotch fire tube boiler design is most commonly referred to as the scotch marine boiler. With this design, the furnace is a big diameter tube located inside of the boiler.
Aug 19, 2019 · Now that we have covered the fire-tube boiler, let’s have a look at a water-tube boiler. The design is fairly similar to a fire-tube boiler, but instead of the furnace heating fire tubes to heat water in a tank, the furnace heats water tubes inside the furnace.
Jul 27, 2016 · In this article we will study about what is a boiler? Different types of boiler (steam). The boilers are used in power plants for the generation of steam. They are crucial for the working of a power plant. They are mostly used in the power plants where steam turbines are used for the generation of electricity.
Nov 08, 2016 · Firetube boilers are commonly used for applications ranging from 51 up to 2,200 horsepower. These types of boilers use a cylindrical vessel with the combustion gases inside of the tubes and the flame located in the furnace. In addition to housing the tubes and furnace, the vessel also houses the steam and water.
Mar 22, 2013 · In many cases, the use of more than two boilers is suggested to allow for a good range of boiler “turn-down” capacity to meet the instantaneous heating load of the building. An example is to use three boilers each at one-third of the required system capacity.
Sep 26, 2017 · While traditional boilers are designed to only provide central heating, some boilers are designed to also function as a hot water heater. Boilers that are designed to provide heating and hot water are either: Tankless coil systems. Indirect systems. Tankless coil systems use the boiler’s heat exchanger to heat water on demand. That means, any time you turn on a hot water faucet, water will run over that hot heat exchanger, heat up and be delivered to you.
In a firetube design, a steam boiler is a pressure vessel comprised of a large shell in which the hot gases of combustion pass through one or more boiler tubes connected to the front and rear boiler sheet. The most common firetube type is the scotch marine firetube boiler, which utilizes a large furnace tube and many smaller boiler tubes.
Types of steam boiler. When hot gases and flames are passed through the tubes or multi-tubes which are surrounded by water, is called fire tube or smoke tube boiler.It is very simple small capacity type boiler and is used various industries for it's simplicity. Example:Cochran boiler,Lancashire boiler,Cornish boiler etc. In water tube boiler,water
Fire tube boilers steam boilers maybe either high or low pressure boilers. The three types of fire tube steam boilers are horizontal return tubular boiler, scotch marine boiler, and vertical fire tube boiler. All fire tube boilers have the same basic operating principles.
Fire-tube boiler - Wikipedia 2019-8-18 · 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.
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.
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
BOILER TYPES FOR STEAM APPLICATIONS III. Firetube Boilers Firetube boilers have been one of the predominate boiler designs for well over a century, and even today they represent a majority of the high pressure steam generating capacity for units in the normal size range. Not all Firetube boilers are created the same.
Firetube boilers are available in either dryback or wetback design. They are identified by the type of reversal (turnaround) chamber, or posterior portion of the combustion chamber, through which flue gasses travel through the furnace to second-pass tubes to heat water within the boiler.
