Water-tube boilers hold the pressured steam in the tubes, hence their large size. They have a steam capacity of 4,500 - 12,000 kg /hr, with very high pressure. Operation. In general, the water tube boiler design includes several drums. Specifically, the lower water drum and the upper steam drum, which are connected by tubes that form the

Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell. Shell boilers may also be referred to as 'fire tube' or 'smoke tube' boilers because the products of combustion pass through the boiler tubes, which in turn transfer heat to the surrounding boiler water.

Fatigue accounts for 80% of the failures investigated in fire tube boilers and 28% in water tube boilers. Significantly in the non-sugar, watertube section this rises to 36% but drops to 17% for sugar boilers. However despite its low incidence in the sugar industry, it is worth a close look at the

The total heating surface of a boiler includes all parts of the boiler which are exposed on one side of the gases of combustion and on the other side to the water and steam being heated The heating surface incudes: generating surface, generating tubes, screen tubes, waterwall tubes, support tubes, superheater surface, and economizer surface

In the same way, a fuel source is burned in the furnace, causing the water tubes inside to heat up. Once again, when the water is boiled, steam is generated and moved downstream. A water-tube boiler is more thermally efficient than a fire-tube boiler, but they are more complex to construct and the quality of the water can be a limiting factor.

See Comparisons of water tube and Smoke tube boilers. This style of boiler still see active service were low quantities of low quality steam are required, such as for cargo and fuel tank heating when in port. This style of boiler is relatively cheap, supplied as a packaged unit and requires less stringent feed water conditioning and level
