6 FAQs about [Steam accumulator specifications]

How big should a steam accumulator be?

Therefore, the accumulator size of 7 metres long by 4 metres diameter provides sufficient capacity for this particular example. A suitably ranged pressure gauge is required to show the pressure within the steam accumulator. Ideally it should be marked to show: Minimum pressure (plant steam pressure). Maximum pressure (boiler steam pressure).

What are steam accumulators?

Using Design codes ASME, PD 5500 or BS EN 13445 we are able to Design and manufacture to meet your requirements. Steam Accumulators, as the name suggets, accumulate energy in the form of steam. When the output from the boiler is met with a lower demand from process, this steam can be injected into a mass of water which is stored under pressure.

How much steam does a steam accumulator release?

Steam accumulator: Note that this 2 797 kg of flash steam will be released in the time taken for the pressure to drop. If this has been an hour, the steaming rate is 2 797 kg/h; if it were over 30 minutes, then the steaming rate would be:

What is the maximum capacity of a steam accumulator?

Processes with saturated steam as work-ing medium in the temperature range of 100–200 °C are the typical applications. Although very large steam accumulators have been demonstrated in power plant applications, the maximum capacity is typically limited to 5–10 MWh for a sin-gle module.

What should a steam accumulator pressure gauge show?

A suitably ranged pressure gauge is required to show the pressure within the steam accumulator. Ideally it should be marked to show: Minimum pressure (plant steam pressure). Maximum pressure (boiler steam pressure). Vessel maximum working pressure.

What is a steam accumulator storage tank?

The storage tank of a steam accumulator must be able to withstand the pressure of the water, including hydrostatic pressure. The storage tank accounts for the larg-est portion of the capital cost of a steam storage tank. One focus of the design is to minimize the mass of the storage tank for safe operation.
