  2. Internally rifled boiler tubes - Wikipedia

    en.wikipedia.org/wiki/Internally_rifled_boiler_tubes

    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.

  3. Three-drum boiler - Wikipedia

    en.wikipedia.org/wiki/Three-drum_boiler

    The design of the Normand gave a particularly large heating area (tube surface area) in relation to the grate area. [8] The cost of this was a dense nest of tubes, where each of the numerous rows of tubes was bent into a different and complex shape. Tube ends entered the cylindrical drums perpendicularly, for good sealing.

  4. Fire-tube boiler - Wikipedia

    en.wikipedia.org/wiki/Fire-tube_boiler

    The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes ...

  5. Vertical boiler with horizontal fire-tubes - Wikipedia

    The design by Robertson of Fleetwood, Lancashire, was originally used in steam wagons. It was often used in similar situations to the Sentinel boiler, but has fire-tubes rather than watertubes. It is best known from its popularity in model engineering, as a multi-tube boiler that's relatively easy to construct.

  6. Flow distribution in manifolds - Wikipedia

    Thus the flow rate of the straight pipe is greater than that of the vertical one. Furthermore, because the lower energy fluid in the boundary layer branches through the channels the higher energy fluid in the pipe centre remains in the pipe as shown in Fig. 4. Fig. 4.

  7. Yarrow boiler - Wikipedia

    en.wikipedia.org/wiki/Yarrow_boiler

    The circulation in a Yarrow boiler depended on a temperature difference between the inner and outer tube rows of a bank, and particularly upon the rates of boiling. Whilst this is easy to maintain at low powers, a higher pressure Yarrow boiler will tend to have less temperature difference and thus will have less effective circulation. [2]
