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
There is as much difference between cleaning an industrial fire-tube boiler and a large utility boiler as there is building a house and a skyscraper. Just because you are a good house builder
In this example a boiler test pump was used, but a test can also be conducted using mains water pressure and a suitable gauge. Test pressure was 60psi and this was held for 10 minutes without change to prove the boiler safe and leak free. Following this test, the safety valve was inserted and adjusted to leak water at 30psi.

The fire-tube boiler, of riveted construction and with a copper firebox, is a far from irrelevant technology, despite its obsolescence, and is (as the above user has so eloquently described) the type seemingly most likely to suffer a boiler explosion, and an explosion with fairly terminal consequences for anyone nearby at that.
The boiler shown in Fig. 16 is a common form; externally it is like the boiler represented by Fig. 15, but within, it has a somewhat different construction. It resembles a multitubular boiler placed on end. The fire box is made of an inner cylinder stayed to the outer.
The Scotch boiler is a fire-tube boiler, in that hot flue gases pass through tubes set within a tank of water. As such, it is a descendant of the earlier Lancashire boiler , and like the Lancashire it uses multiple separate furnaces to give greater heating area for a given furnace capacity.

A fire tube boiler, generating steam for a fruit processing plant, failed catastrophically. Figure 1 shows a typical fire tube boiler layout. Coal is conveyed and combusted in the furnace while heat is extracted via forced air convection. The heated air is carried in three passes through the boiler shell, heating the water surrounding the
In the boiler world, most upgrades over the years have been small innovative steps rather than anything highly revolutionary as the industry continues to improve safety and efficiency and to control emissions. Today, efficiency is the name of the game, and recently, companies have been focusing on
In fire-tube boilers, the flue gas passes inside boiler tubes, and heat is transferred to water on the shell side. A dynamic model has been developed for the analysis of boiler performance, and
A water tube boiler is able to operate at higher pressures than other systems, which makes it an attractive option for some situations. The fire tube boiler design is much weaker, and this makes it unsuitable for high pressure boilers. Water tube boilers are more modern and a more sophisticated

Water tube boilers typically require higher pressures, and more flow from the boiler feed water pumps than fire tube boilers. 4. Boiler feed water pumping applications typically require high pressures due to the high temperatures of the feed water. Water changes to a gas state at 212-degrees F in atmospheric pressure.
Re: Boiler Build I don't think you want to build a fire tube boiler out of cast iron. it might make a neat housing for a water tube boiler say using a long copper tube coil for steam generation
Feb 14, 2016 · The Boiler: I've spent countless hours searching for info on them. There are basically 2 types, Fire Tube and Water Tube. From what I've read, Water Tube seems to be the easiest to build, safest (depending on who you talk to), and fastest to come up to pressure. They, however, tend to not do well with changing steam demand.
The fireside of the tubes can also be subject to scale and deposit build-up when the boiler is fired with oil or solid fuel. This adversely affects boiler efficiency and can cause the tubes to overheat. Tube ends that are projecting beyond the tube sheet more than the Code allows can overheat and crack.
The tubes slope upwards from the chimney end, where the heat is less, to the fire-door end, where the heat is fiercer, and a good circulation is thus assured. The Babcock and Wilcox boiler is the highest development of this system, which has proved very successful, and may be recommended for model boilers of all sizes.
Outdoor Wood Boiler From Junk: Outdoor wood boilers have become a popular option in the cold country for heating the home. The advantage is that you keep all the smoke, mess, and fire danger outside and away from the house.

I maybe wrong here but, isn't another reason a fire-tube boiler is better on a locomotive due to the stresses put on the boiler? Unlike a boiler in a building a steam locomotive's boiler is mobile, outside in different temps and weather, and the pressure is almost constantly changing.
Due to its shape the boiler is also known as spheroid. The main feature of the boiler is that the furnace of the boiler is surrounded by water and therefore there is no requirement of refractory material. It is a single phase pass boiler, which means that the hot gases pass just through the horizontal tube stack before going to the exhaust.
Locomotive boiler is a horizontal drum axis, multi-tubular, natural circulation, artificial draft, forced circulation, mobile, medium pressure, solid fuel fired fire tube boiler with internally fired furnace. It is used in railway locomotive engines and in marine. It is a mobile boiler and has high steam generation rate. Construction. Get a quote
