  2. Stirling boiler - Wikipedia

    en.wikipedia.org/wiki/Stirling_boiler

    Five-drum form, section. Note the chain-grate automatic stoker (left). The Stirling boiler is an early form of water-tube boiler, used to generate steam in large land-based stationary plants. Although widely used around 1900, it has now [when?] fallen from favour and is rarely [clarification needed] seen [by whom?] .

  3. Water-tube boiler - Wikipedia

    en.wikipedia.org/wiki/Water-tube_boiler

    Water-tube boiler. A high pressure watertube boiler [1] (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by 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 ...

  4. Spiral watertube boiler - Wikipedia

    en.wikipedia.org/wiki/Spiral_watertube_boiler

    Spiral water-tube boilers are a family of vertical water-tube boilers. Their steam generating tubes are narrow spiral tubes, arranged in circular fashion around a central vertical water drum. The water tubes are long, numerous and of 2 inches (50 mm) diameter, or smaller. This gives an extremely large heating area, and so good steam raising ...

  5. Field-tube boiler - Wikipedia

    en.wikipedia.org/wiki/Field-tube_boiler

    Field tube, sectioned. A Field-tube boiler (also known as a bayonet tube [1] ) is a form of water-tube boiler where the water tubes are single-ended. The tubes are closed at one end, and they contain a concentric inner tube. Flow is thus separated into the colder inner flow down the tube and the heated flow upwards through the outer sleeve.

  6. Shell-and-tube heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Shell-and-tube_heat_exchanger

    A shell-and-tube heat exchanger is a class of heat exchanger designs. [1] [2] It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes ...

  7. Monotube steam generator - Wikipedia

    en.wikipedia.org/wiki/Monotube_steam_generator

    Monotube steam generator. Herreshoff steam generator in a Peruvian torpedo boat of 1879. A monotube steam generator is a type of steam generator consisting of a single tube, usually in a multi-layer spiral, that forms a once-through steam generator (OTSG). The first of these was the Herreshoff steam generator of 1873.
