Fire-tube boiler : definition of Fire-tube boiler and

A fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank

What are the various types of tubes used in water tube

2010-8-3 · In the majority of cases boiler tubes are expanded, and then bell-mouthed into drums or headers. For large diameter tubes, such as downcomers, grooved seats are used to assist the expansion in forming a tight seal. Where high temperatures are involved, as with superheater tubes, welding may be used in place of expanding. Tubes Attachments

MECHANICAL DESIGN OF HEAT EXCHANGERS

Heat transfer equipment may be designated by type or function it performs, such as chiller, condenser, cooler reboiler, etc. The choice of shell and tube type is determined chiefly by factors such as the need for the provision for differential movement between shell and tubes, the design pressure, the design temperature, and the fouling nature of the fluids rather than the function.
