once-through boilers - thermopedia


Once-through boilers are generally associated with high pressure operation and the feed water enters at high sub-critical (>180 bar) or supercritical pressure whilst superheated steam leaves at a pressure some 20–30 bar lower. Sliding pressure operation is adopted to …

2019-6-10 · A boiler or steam generator is a device used to create steam by applying heat energy to water.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.

The Leander-class frigates did have Babcock & Wilcox boilers but of a more conventional two-drum design, one water drum and one steam drum, much like a Yarrow boiler without the second water drum. The water drum was offset to one side and below the furnace and steam drum. The two boilers fitted were ‘handed’ with the water drum inboard on both.

1972-10-17 · In the application of such boilers to a nuclear reactor plant, it is necessary to employ, in some circumstances, ` once-through` boilers in which the flow of water and steam is vertically downwards. Such boilers are suitable for use with high temperature reactors where the cooling gas from the reactor flows downwards through the reactor core.

2003-10-30 · Fire tube boilers generally have tubes with a diameter of 5 cm or larger. They are usually straight and relatively short so that the hot gases of combustion experience a relatively low pressure drop while passing through them. The path of the flue gases goes from burners/grate, through one of the chambers, to the other end of the chamber.
