Flow and heat transfer of supercritical water in a rifled

To provide better insights into design and practical operation of supercritical boilers, the present work investigated flow and heat transfer of supercritical water in a rifled tube with axially non-uniform heating, under p = 22.627.3 MPa, G = 350800 kg/(m 2 ·s) and several types of heat flux profiles. The main conclusions are as follows:

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.

Study and Analysis on Boiler Tubes for Performance

frictional pressure drop in a vertical rifled tube of the boiler in two-phase flow and condition of 0.6MPa in the smooth tube. Outside diameter of rifled tubes used in the experiment was 22mm, inner diameter 11.6mm, width if a rib was 5.5mm, the height of rib was 0.4mm-0.6mm and pitch of rib was3.5mm.

Multi-Rifled seamless cold drawn tubes for power plants

Multi Rifled Tubes are used in high pressure boilers to eliminate the steam film effect due to the D. N. B. on the inner surface of the tube and raise thermal efficiency in the furnace walls. Rifled tubes in a conventional boiler provide a larger margin of safety for natural circulation and assisted circulation and many economical advantages.

Rifle Tubes | Canadas Oil Sands Innovation Alliance - COSIA

Rifle Tubing technology involves using a rifled or ribbed tube instead of smooth tubes currently used in boilers that produce steam for SAGD. The internal ribbing of rifle tubes introduce centrifugal force in the tubes, not present in traditional, smooth tubes, helping to turn water into steam uniformly and more efficiently.

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. Current research into these tubes is being conducted due to their potential to increase efficiency of power plants.

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.
