Apr 17, 2015 · Type of water tube boiler Simple vertical boiler A vertical boiler is a type of water- tube boiler where the boiler barrel is oriented vertically instead of the more common horizontal orientation. Vertical boilers were used for a variety of steam- powered vehicles and other mobile machines, including early steam locomotives. 24.
The main classification of boilers is in two categories i.e. water tube boilers and fire tube boilers. Fire tube boilers are useful for small demands of steam and water tube boilers are useful for industrial level usage. To cut short the main purpose of boiler is to boil a liquid mostly the water in order to generate the steam for serving the purpose of heating a building or running an equipment through pressurized steam or pressurized water.

Water tube boilers also have a downcomer tube that connects the steam drum to the feed water drum. If the steam cools and condenses back into water droplets, that water can drain from the steam drum to the feed water drum via the downcomer tube.
Unlike firetube boilers, watertube boilers pass water through the tubes, which are then heated externally by hot gas from the furnace flue gas. The heated water rises into a steam drum, where it can then be reheated by a superheater to achieve even higher steam temperatures - this superheated steam is a dry gas most commonly used to drive turbine engines used in thermal power stations.
