The differences between fire tube, water tube and process heat boilers are given below. Fire tube boilers: In fire tube boilers, water is heated when combustion gases are circulated in the tubes. Water is directed through the shell and gases are directed through the tubes. Boiling of water takes place and steam is formed which is directed out
Difference between Fire tube boiler and water tube boiler Structure. Steam pressure limit of the fire tube boiler is lies between 20-30 bar and the pressure limit of the water tube boiler is much more than the fire tube boiler and is unlimited within the design limits.

Water is inside the tubes of a water tube boiler and outside the tubes of a fire tube boiler.
Fire-tube Boilers. In fire-tube boilers, combustion gases pass through the inside of the tubes with water surrounding the outside of the tubes. The advantages of a fire-tube boiler are its simple construction and less rigid water treatment requirements.
Nov 24, 2016· Fire Tube boiler is the simplest form of the internal furnace, vertical fire tube boiler.Fire tube boilers are a portable boiler and it requires a small floor space. The steam rating in fire tube boilers doesnt exceed 2500 kg per hour and pressure is limited to 10 bars.
What is a water tube boiler? Water tube boilers were developed for a variety of reasons, including the need for higher steam pressures, higher steam generation rate, superheated steam. these types of boilers have quicker response to load changes. We briefly discuss about Water tube boiler parts and functions.
Aug 22, 2018· 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.
Aug 17, 2018· Classification of boilers. 2.Fire Tube and Water Tube In the fire boilers, the hot gases are inside the tubes and the water surrounds the tubes. The whole point is
This video contains the difference between fire tube boiler and water tube boiler. Difference Between Fire Tube Boiler And Water Tube Boiler ZBG fire tube boilers include WNS oil and gas fired boiler and DZL packaged boiler, capacity 1 ton/hr ~20ton/hr. ZBG water tube boilers include SZS oil and gas boiler
Recovery of some of this heat loss to the extent of 30 to 50 percent is possible by means of an exhaust gas boiler or water heater. 2014 Water Tube Boilers; October 12 circulation system cooling water system cross head bearing oil system cylinder lube oil system diesel engines explosimeter fire detectors fire fighting fire triangle
Oct 28, 2014· Steam Boilers OR Steam Generators Differences between Water-tube and Fire-tube boilers Particulars Fire tube boiler Water tube boiler Position of water and hot Hot gases inside the tubes and gases water outside the tube Water inside the tube and hot gases outside the tubes Mode of firing Generally internally fired Externally fired Operating
The difference between the two is that the Water tube boilers are safer and last much longer than the fire tube boiler. Their size is also larger and have a faster recovery time.

Modern Boiler Types and Applications This chapter will present mainly water tube boiler types, categorized by their combustion process and application. boilers. The radiation differences in the flue gases of oil and gas are too high in order to use Figure 6: PCF-burner [Andritz].
Vertical this type of boiler is a one-pass boiler with the furnace at the bottom and tubes running between the lower and upper tube sheets. The furnace can be enclosed on its sides with a water cooled jacket or it may be made up of masonry. The top tube sheet in a steam boiler can be above or below the water
Mar 19, 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. This is the key difference between these boilers.
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
Steam Generators vs. Steam Boilers. 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
