Fire tubes boilers are also known as a smoke tube boiler. Water-tube boiler: Water-tube boilers are those boilers in which water flows through a number of tubes (called water tubes) and the hot gases produced by the combustion of fuel in the boiler furnace while on their way to chimney pass surrounding the tubes.

Shell and tube heat exchanger is a device where two working fluids exchange heats by thermal contact using tubes housed within a cylindrical shell. The fluid temperature inside the shell and tube are different and this temperature difference is the driving force for temperature exchange. They can be used for wide temperature and pressure range.

As far as why you might need them is application specific. Perhaps you have something sliding or moving and want to reduce friction as much as possible. Another application might be in a pressure regulator where rough radii cause turbulent flow resulting in a 'water' hammer effect that adversely affects your flow.

Venturi tubes, which are constrictions or "throats" in fluid conduits, are regions of reduced pressure that are used in a number of devices. A perfume atomizer, for example, operates by having air forced from a squeeze-bulb through a Venturi throat that reduces the pressure above an open tube dipped into liquid perfume.
