Boiler - an overview | ScienceDirect Topi

Stephen Hall, in Branan's Rules of Thumb for Chemical Engineers (Fifth Edition), 2012. Introduction. 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 ...

Yarrow boilers are an important class of high-pressure water-tube boilers.They were developed by Yarrow & Co. (London), Shipbuilders and Engineers and were widely used on ships, particularly warships. The Yarrow boiler design is characteristic of the three-drum boiler: two banks of straight water-tubes are arranged in a triangular row with a single furnace between them.

Water Tube Boiler Operation | DoItYourself.c

A water tube boiler is able to operate at higher pressures than other systems, which makes it an attractive option for some situations. The fire tube boiler design is much weaker, and this makes it unsuitable for high pressure boilers. Water tube boilers are more modern and a more sophisticated design than fire tube designs.

Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships.They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.
