A fire tube boiler, as the name suggests, has the hot flue gases from the combustion chamber, the chamber in which combustion takes place, passing through tubes and out the boiler stack. These tubes are surrounded by water. The heat from the hot gases transfers through the walls of the tubes and heats the water.
30-08-2019· Fire Tube Boiler In Fire Tube Boilers, hot flue gases will be flown inside the tube and these tubes are surrounded by water. These are the low-pressure boiler which cannot generate much heat compared to water tube boilers. As the production of heat is less the overall efficiency of this boiler is also low.
So the definition of a fire-tube boiler is one type of boiler that flows the heat of the combustion process into one or more pipes, which were inside a sealed container filled with water. Fire-tube boiler is the simplest type of boiler.
Fire-Tube Boilers Return-Tube Boilers Horizontal 2-6â€‚·â€‚The combustion chamber in which the products of combustion are completely burned, is formed of flat and curved plates flanged at the edges and riveted together. The shape of the plates is shown in Fig. 21, which is a sectional view of a single-ended marine boiler.
Overview2020-2-14â€‚·â€‚The immersion fired boiler is a single-pass fire-tube boiler that was developed by Sellers Engineering in the 1940s. It has only firetubes, functioning as a furnace and combustion chamber also, with multiple burner nozzles injecting premixed air and natural gas under pressure.

The hot gases from the grate pass through the combustion chamber to horizontal fire tubes and transfer the heat to water by convection. Exhaust gases out from fire tubes pass through smokebox and exhaust to the atmosphere via a chimney. There is a door in the smokebox for cleaning the fire tunes and smokebox. The Cochran boiler has a working pressure of 6.5 bar and a steam capacity of 3500 kg/hr. â€¦
2004-3-19â€‚·â€‚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.
