Working principle of water tube boiler:

Water tube is a type of boiler during which water circulates in tubes heated externally with the fire. Fuel is burned inside the furnace, creating hot gas which heats water within the steam-generating tubes. In smaller boilers, additional generating tubes are separate within the furnace, while larger utility boilers depend upon the water-filled tubes that comprise the walls with the furnace to build steam.7HPHorizontal boiler

The heated water then rises in the steam drum. Here, saturated steam is drawn off of the the top drum. In certain services, the steam will reenter the furnace through a super heater being super heated. Super heated steam pertains to steam that is certainly heated above the boiling point in a given pressure. Super heated steam can be a dry gas and thus accustomed to drive turbines, since water droplets can severely damage turbine blades.7HPHorizontal boiler
Cool water towards the bottom of the steam drum returns towards feed water drum via large-bore 'down comer tubes', where it pre-heats the feed water system. (In large utility boilers, the feed water comes for the steam drum as well as the down comers supply water to the bottom on the water walls). To improve economy of the boiler, exhaust gases may also be utilized to pre-heat mid-air blown into the furnace and warm the feed water system. Such water tube boilers in thermal power stations are also called steam generating units.7HPHorizontal boiler

Water tube boiler applications:

The ability of water tube boilers to generate super heated steam makes these boilers particularly attractive in applications that require dry, high-pressure, high-energy steam, including steam turbine power generation.7HPHorizontal boiler
