The common steam locomotive boiler is a horizontal straight fire tube boiler with riveted cylindrical boiler courses, a stayed internal firebox at the rear, and a smokebox at the front. Operating pressure ranges up to 300 psi. The boiler shell is made up of cylindrical sections or courses which may be straight or tapered.Learn More
Apr 19, 2005 · It was therefore decided to adopt a water-tube firebox combined with a conventional cylindrical fire-tube boiler. In this it resembled the Brotan-Defner boiler. In December 1905 the first boiler was ordered from the Creusot works. Trials were concluded in 1907. The bottom steam drums were of cast steel, protected from the direct heat of the Learn More
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.Learn More
Fire-tube boilers sometimes have water-tubes as well, to increase the heating surface. A Cornish boiler may have several water-tubes across the diameter of the flue (this is common in steam launches). A locomotive boiler with a wide firebox may have arch tubes or thermic syphons. These both increase the heating surface and give additional Learn More
In water-tube boilers, the firebox is usually a firebrick-lined compartment below the water tubes. Marine boiler firebox. In marine boilers there are also various types of firebox. The main distinction is, again, between fire-tube types (e.g. the Scotch boiler, with internal firebox) and water-tube types (e.g. the Yarrow boiler, with externalLearn More
According to flow of water and hot gases: 1. Water tube. 2. Fire tube. In water tube boilers, water circulates through the tubes and hot products of combustion flow over these tubes. In fire tube boiler the hot products of combustion pass through the tubes, which are surrounded, by water. Fire tube boilers have low initial cost, and are more Learn More
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. Fire-tube boilers, typically have a lower initial cost, are more fuel-efficient, and are easier to operate.Learn More
Jul 30, 2009 · Most of the fire tube boilers now come in a complete package.The main parts of the package are : oil burners. fuel pump. forced draft fan. feed pump. automatic control system. Boiler mountings. The most basic type of a package boiler is single passage three pass design. One such boiler is shown in the figure.Learn More
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 pressureLearn More
Fire-tube boiler: Fire-tube boiler is those boiler in which the fire or hot gas is present inside the tubes and water surrounds these fire tubes. Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water.Learn More
In a conventional fire tube boiler, the hot gases move from the firebox into heating tubes immersed by water in the tank. As the walls of the tubes are heated by the gas, the heat transfers into the water, eventually converting the hot water to steam. While this design is quite common, it is also fairly inefficient for a couple of reasons.Learn More

Aug 01, 2007 · water tube boiler tube leak that cannot be found. Our Nebraska D type package water tube boiler has developed a leak that we cannot locate. This boiler was put into service in 1990. Its MAWP is 200 psi and its max rating is 55,000 #/hr.. We operate it at 90 psi and average 30,000 #/hr. during the winter months.Learn More
Feb 19, 2015 · 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. Here are a few key differences between the two: Firetube Boilers: - compact construction.Learn More
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 of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. Their advantage over boilers with a single large flue is Learn More
