A fire-tube boiler's principal elements include a cylindrical shell, a set of tubes, a feedwater channel line, and a combustion gas vent stack. The name fire tube is very picturesque. The fire, or hot flue gases from the stove, is led through a group of steel pipes that are enclosed by a shell loaded with 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. The furnace and boiler are circumferenced by water. Some of the larger, older scotch boilers would have two or even three different

In a water-tube boiler, it contains a minimal amount of water at any given time. It may be just one-tenth the volume of a fire tube boiler, which requires a larger volume of water to act as a heat shield so that metal in the boiler doesn't melt and create problems. When fire tube boilers run low on water, the metal in the boilers shrinks.
The dryback boiler reversal chamber has a rear wall that is lined, or jacketed with refractory, which passes combustion gasses from the furnace to multiple tube sheets and reflects burner heat, resulting in exterior radiation losses. The dry back boiler design uses a common rear tube sheet and features convenient fire-side and water-side access.
A vertical boiler with horizontal fire-tubes is a type of small vertical boiler, used to generate steam for small machinery. It is characterised by having many narrow fire-tubes, running horizontally.. Boilers like this have been widely used on ships as either auxiliary or donkey boilers. Smaller examples, particularly the Robertson type have been used for steam wagons
