Fire-tube boiler: Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.The furnace can be situated at one end …

Heating boilers are also classified as to the method of manufacture, i.e., by casting (cast iron boilers) or fabrication (steel boilers). Those that are cast usually use iron, bronze, or brass in their construction. Those that are fabricated use steel, copper, or brass, with steel being the most common material.

The first quality of a boiler material that comes to mind is ductility - you want a material that will withstand many,many heating and cooling cycles, with out fatiguing and cracking. Strength is almost secondary - the strength of a boiler is in its structure. Up to about 5 1/2 - 6" diameter and 100 PSI copper has many advantages,above that,low carbon steel is the material of choice. I worked as a …

The tubes for fire tube boilers are usually made out of metal composites and can contain lead, steel and/or other metallic elements or alloys. Fire tube boilers are generally very large and many

The most common type of simple vertical shell boiler direct fired gas water heat exchanger. Vertical boilers are compact and take up a small floor area. Vertical steam boilers have relatively low outputs. The cross tube is one of the smaller and simpler boilers.

  • OverviewFiretube boilers are used for low capacity steam production applications, mainly for vessels having diesel engines as main propulsion system. On such vessels, steam is required for auxiliary machinery. Such boilers have simple operation and can run properly even with medium quality water.
