  Internally rifled boiler tubes - Wikipedia

  Internally rifled boiler tubes are used to evaporate water into steam inside boilers of thermal power plants.Because of their internally rifled shape, they are more efficient. The boiling crisis takes place later, thus allowing for greater heat transfer between the pipe and the fluid inside the pipe. Costs of this type of tube are generally higher than plain tubes.

  Water-tube boiler - Wikipedia

  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 heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

  Multi-Rifled Tubes - ISMT Limited

  Rifled Smooth Multi-Rifled Tubes IMpRoved boIleR effIcIency Rifled tubes are used in heat exchangers and boilers to provide highly energy efficient means of heat transfer. The presence of the internal rifling induces centrifugal forces in the mass flow thereby separating the water from the steam fraction and for-cing the water towards the tube

  Understanding the Boiler Furnace Wall Construction

  Tangent tube; Monowall or membrane wall; Tangent Tube. In tangent tube arrangements, small diameter tubes are closely pitched together to form an arrangement backed by three layers, namely - refractory, insulation and boiler casing. The problem with this arrangement is that, in case of tube failure the welded repairs become a bit difficult to

  Steam Boiler: Construction of Water Wall Tubes

  Studded Tube Water Wall This type is continuous development from the above type. The advantage of this type is can give higher efficiency because the construction of studded tube water wall protects refractory effectively. If the corrosion attack the lagging and tubes, so leakage will occurs when flue gas flow through the water wall(see figure 3).
