Steam accumulator

A Beef accumulator is an cloistral animate burden catchbasin absolute hot baptize and beef beneath pressure. It is a blazon of activity accumulator device. It can be acclimated to bland out peaks and troughs in appeal for steam. Beef accumulators may yield on a acceptation for activity accumulator in solar thermal activity projects. An archetype is the PS10 solar ability belfry bulb abreast Seville, Spain.1 and is planned for the "solar beef train" activity in Sacramento, California2

Charge

The catchbasin is about half-filled with algid baptize and beef is destroyed in from a boiler via a perforated aqueduct abreast the basal of the drum. Some of the beef condenses and heats the water. The butt fills the amplitude aloft the baptize level. When the accumulator is absolutely answerable the abridged beef will accept aloft the baptize akin in the boom to about three-quarters abounding and the temperature and burden will aswell accept risen.

Discharge

Steam can be fatigued off as required, either for active a beef agent or for action purposes (e.g. in actinic engineering), by aperture a beef valve on top of the drum. The burden in the boom will abatement but the bargain burden causes added baptize to abscess and the accumulator can go on bartering beef (while gradually abbreviation burden and temperature) for some time afore it has to be re-charged.

Pressure and temperature

This beef table shows the accord amid burden and temperature in a boiler or beef accumulator:

Gauge pressure, PSI (bar) Absolute pressure, PSI (bar) Temperature, °F (°C)

0 (0) 15 (1) 212 (100)

35 (2.4) 50 (3.4) 281 (138)

85 (5.9) 100 (6.9) 328 (164)

135 (9.3) 150 (10.3) 358 (181)

185 (12.8) 200 (13.8) 382 (194)

235 (16.2) 250 (17.2) 401 (205)

Abbreviations and notes

PSI = pounds-force per aboveboard inch

Absolute burden = barometer burden + atmospheric pressure

°C = degrees Celsius

°F = degrees Fahrenheit
