Boilers are classified into different types based on their working pressure and temperature, fuel type, draft method, size and capacity, and whether they condense the water vapor in the combustion gases. Boilers are also sometimes described by their key components, such as heat exchanger materials or tube design.
147 The Circulation of Water and Steam in Water-Tube Boilers, and the Rational Simplification of Boiler Design By W. Yorath Lewis, M.I.Mech.E.,* and Struan A. Robertson, B.Sc. (Eng.)? The authors stress the need for a sound theory of circulation in water-tube boilers, to enable weight and space to be saved and efficiency and reliability to be increased.
The fire tube boiler was created in the 1800s, Fig. 1.7.Its main use was to run steam engines for motive power. One of the first brand names for this type of boiler was the Lancashire boiler, which used two parallel fire tubes. It was used to power steamboats and railroad engines and to run industrial machinery via belt drives.

The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At first, the water is supplied into the steam type drum with the help of a water pump. Whenever the fuel is burned, then hot gases will be generated that are permitted to supply in the shell part of the boiler.
Fire Tube or Shell Boilers. This is the most common type of boiler used in small and medium sized industrial installations. Fire tube boilers are often produced as 'packaged' units complete with pumps and control system, requiring only connection to a suitable water and fuel supply before commencing operation.
