A boiler is a self-contained combustion system that heats water. The hot water or steam produced by a boiler is then used in heating systems. Although designs vary, a boiler has four main parts: the burner, the combustion chamber, the heat exchanger and the pluming apparatus.
The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water flows from the shell and in water tube boiler, water flows from the tubes and the flue gases from the shell or passes over the tubes. This is the key difference between these boilers. Now I am going to tell you some hidden

These points includes types of fluid flows within the tubes, steam generation rate, floor area required for the steam generation, transportation, efficiency, fluctuating loads, operating cost etc. the knowledge of the difference about these two boiler is very crucial.
Water tubes are available in much larger capacities than fire tubes, and are able to recover a lot faster from a large increase in load demand from a pressure stand point. Meaning if the pressure drops on a fire tube boiler, it takes longer to come back up than on a similarly rated water tube boiler. Fire tube boilers typically have lower
The earliest form of fire-tube boiler was Richard Trevithick's "high-pressure" Cornish boiler. This is a long horizontal cylinder with a single large flue containing the fire. The fire itself was on an iron grating placed across this flue, with a shallow ashpan beneath to collect the non-combustible residue.
A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are…

Many systems combine these two separate boiler-safety functions into one unit. They are designed to ensure the water level within a boiler never falls below a predetermined amount. Should that situation occur, the system is designed to shut down the boiler by cutting off its fuel. Proper functioning requires operators to make sure no build-up

encompassed both fire-tube and water-tube boilers with a further subdivision of water tube boilers into sugar and non-sugar boilers. Although there are only a limited number of fire-tube boilers in use in the sugar industry it was felt that seriousness of the failure mechanisms warrants their inclusion in this paper. The statistics
BENT TUBE BOILERS Watertube boilers of the bent tube design are capable of greater steam capacities, higher pressures, and greater versatility in arrangements such as floor space, head room, and more efficient use of the furnace. The furnace may be lined with watertubes (called a water-cooled furnace) to absorb more radiant heat from the fire

Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. 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
In steam locomotive use, by far the most common form of superheater is the fire-tube type. This takes the saturated steam supplied in the dry pipe into a superheater header mounted against the tube sheet in the steam is then passed through a number of superheater elements—long pipes which are placed inside large diameter fire tubes, called flues.
