    Also, higher steam pressure will be possible than with saturated steam, enabling the steam to carry more energy. Although superheating adds more energy to the steam in the form of heat there is no effect on pressure, which is determined by the rate at which steam is drawn from the boiler and the pressure settings of the safety valves. [12]

    en.wikipedia.org/wiki/Boiler_(power_generation)

    Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator. A boiler or steam generator is used wherever a source of steam is required.

  4. High-pressure steam locomotive - Wikipedia

    en.wikipedia.org/wiki/High-pressure_steam_locomotive

    A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal for other locomotives. Most locomotives operate with a steam pressure of 200 to 300 psi (1.38 to 2.07 MPa). [1] In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa).

  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. A low pressure means low temperature water in the heat exchanger.

    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.

    Napier boiler: A high-domed low-pressure boiler used on early steamships. [41] Also known as the "haystack", although not the usual, and even earlier, haystack boiler. [41] Niclausse boiler: a field-tube boiler, with the field-tubes set at a shallow angle to horizontal. [6] [42] Normand boiler: an early three-drum boiler used mainly by the ...

    A locomotive boiler has two tubeplates: one at the front of the inner firebox (firebox tubeplate) and one at the front of the boiler, adjacent to the smokebox (smokebox tubeplate). Vacuum valve A non-return valve allowing atmospheric air into the boiler, if a cold boiler reduces its internal pressure on cooling down.

  9. Cutoff (steam engine) - Wikipedia

    en.wikipedia.org/wiki/Cutoff_(steam_engine)

    In a steam engine, cutoff is the point in the piston stroke at which the inlet valve is closed. On a steam locomotive, the cutoff is controlled by the reversing gear.. The point at which the inlet valve closes and stops the entry of steam into the cylinder from the boiler plays a crucial role in the control of a steam engine.
