Due to the reduced amount of surface area, scaling can become a problem faster in a Miura boiler than a fire tube boiler. For example, water that could cause 1/16'' of scaling in a Miura boiler would only cause 1/64'' of scaling in a conventional fire tube boiler. Boiler scaling has serious consequences.
Boilers are essentially shell-and-tube heat exchangers, with water being boiled to steam or transformed to high pressure hot water. Heat is generated by burning a fossil fuel; the combustion gas can be ducted around tubes containing the water (water-tube boiler), or the hot gas can pass inside the tubes with the water being in the shell (fire
boiler are employed. For instance, in the "Tyne" boiler (fig. 5) the furnace is hemispherical, and the products of combustion are led into an upper combustion chamber traversed by four or more inclined water-tubes of about 9 in. diameter and by several vertical water-tubes of less diameter.
48) consisted of a platform, on which stood a large water-tube boiler, a number of concavo-convex aeroplanes arranged in tiers like shelves, each making a slight upward angle with the horizon, two very large vertical screws placed aft and propelled by steam engines, tanks for the storage of water, naphtha, &c. The boiler was especially noteworthy.

Lancashire boilers have working pressure in the range of 0.7 Mpa to 2 Mpa. The efficiency of this boiler is 65% - 70%. b) Externally fired boilers: Babcok-Wilcox boiler, Loeffler boiler, etc have furnace outside the boiler shell. In these furnaces, water passing through tubes is surrounded by hot gases.
Water Tube Boilers. Water tube boilers offer advances in steam-producing technology. It is different than fire tube technology in that the flame from the furnace is shot into a large containment area, where it literally bounces off the rear wall and distributes heat more evenly and efficiently, thus reducing fuel costs.
Two primary types of boilers include Firetube and Watertube boilers. In a Firetube boiler, hot gases of combustion flow through a series of tubes surrounded by water. Alternatively, in a Watertube boiler, water flows in the inside of the tubes and the hot gases from combustion flow around the outside of the tubes.
A steam boiler is designed to absorb the maximum amount of heat released from the process of combustion. Heat transfer within steam boiler is accomplished by three methods: radiation, convection, and conduction. The heating surface in the furnace area receives heat primarily by radiation.
For example, steam locomotives have fire-tube boilers, where the fire is inside the tube and the water on the outside. These usually take the form of a set of straight tubes passing through the boiler through which hot gas flows. In a cast iron sectional boiler, sometimes called a "pork chop boiler" the water is contained inside cast iron sections.
