  2. Electric steam boiler - Wikipedia

    en.wikipedia.org/wiki/Electric_steam_boiler

    Water from the system or holding tank is then run over or near this hot element in a pipe or tank, heating the water to a suitable temperature, then making the water hot enough to boil and become saturated steam, [1] at which point the saturated steam is transported to wherever it is needed via the steam pipes that exit the body of the electric ...

  3. Electric boiler - Wikipedia

    en.wikipedia.org/wiki/Electric_boiler

    These classifications are determined based on the boiler's power output, energy performance, model type, energy consumption, and energy efficiency. [2] In a residential setting, an electric boiler is often used as a backup to a house's heating system. During the colder months, heating and hot water is used more frequently.

  4. Electrode boiler - Wikipedia

    en.wikipedia.org/wiki/Electrode_boiler

    The most common type of electrode boiler pumps water from the lower part of the vessel to an internal header that has nozzles that allow the water to flow to electrodes. Generally the working pressure is maintained at 10 bar. If more pressure is needed (more steam) the controls speed up the pump to increase flow through additional nozzles.

  5. Package boiler - Wikipedia

    en.wikipedia.org/wiki/Package_boiler

    A package boiler is a factory-made boiler. Package boilers are available in a range of standard designs. Package boilers are used for heating and act as a steam generator for small power purposes such as self-powered industrial plants. Package boilers are low pressure designs.

    shell boiler: small-tube water-tube boiler: water-tube boilers with small-diameter tubes, 2 inch or less, rather than the older large-tube designs, with tubes of 3 inch and above. Also termed Express or Speedy boilers. Smithies boiler: A development of the pot boiler with added watertubes, used for model steam locomotives. [52]

  7. Flash boiler - Wikipedia

    en.wikipedia.org/wiki/Flash_boiler

    A flash boiler is a type of water-tube boiler. The tubes are close together and water is pumped through them. A flash boiler differs from the type of monotube steam generator in which the tube is permanently filled with water. In a flash boiler, the tube is kept so hot that the water feed is quickly flashed into steam and superheated.

  8. Supercritical steam generator - Wikipedia

    en.wikipedia.org/wiki/Supercritical_steam_generator

    A supercritical steam generator is a type of boiler that operates at supercritical pressure and temperature, frequently used in the production of electric power. In contrast to a subcritical boiler in which steam bubbles form, a supercritical steam generator operates above the critical pressure – 22 megapascals (3,200 psi ) and temperature ...

  9. Vertical boiler with horizontal fire-tubes - Wikipedia

    en.wikipedia.org/wiki/Vertical_boiler_with...

    Cochran boiler. A vertical boiler with horizontal fire-tubes is a type of small vertical boiler, used to generate steam for small machinery. It is characterised by having many narrow fire-tubes, running horizontally. Boilers like this have been widely used on ships as either auxiliary or donkey boilers.
