Internally rifled boiler tubes - WikipediaAccording to the Wikipedia article you referenced in your comment, the advantage of rifling in a boiler tube is that it creates centrifugal force which throws the heavier water phase toward the walls of the tube, keeping the lighter steam phase in the center.THERMO HYDRAULICS OF A STEAM BOILER FORCED CIRCULA- TION WITH RIFLED …tubes for the nominal boiler load. At first sight so small difference is not expected, since the increase of the frictional pressure drop in the rifled tube, compared with the smooth tube, is approximately 90% higher in case of two-phase flow with 30% quality and the

Experimental investigation on heat transfer and frictional …Internally multi-lead rifled steel tubes shall be applied on water wall of power plant boilers, as main component for heat exchange, the rotary movement of water caused by internal spiral ribs can eliminate steam film on tube inner surface and thus achieve nucleate boiling. There are two types of in ShareWater-tube boiler - WikipediaWater-tube boiler. A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in
