Electrically heated steam accumulator

How does a steam accumulator work?

The steam accumulator is designed with a large water surface and sufficient steam space in order to produce high quality steam almost instantaneously during periods of peak demand. In the case of some vertical steam accumulators the steam space is enlarged to compensate for the smaller water surface. Water

What is water in a steam accumulator?

Water Water in the steam accumulator is steam that has condensed and is therefore clean and pure, with a typical TDS level of 20 - 100 ppm (compared with a shell boiler TDS of seldom less than 2 000 ppm) which promotes a clean and comparatively stable water surface.

Can a steam accumulator overload a boiler?

If the steam accumulator is connected to a boiler rated at 5 000 kg/h, and supplying an average demand within its capacity, the combined boiler and accumulator outputs could meet average overload conditions of 5 594 + 5 000 = 10 594 kg/h for 30 minutes.

How can a flash steam accumulator be used to produce wet steam?

Enough water must be stored to provide the required amount of flash steam during the discharge period. This can be satisfied by ensuring the accumulator volume is large enough. Higher steam release rates will produce wet steam. The velocity and flowrate at which the flash steam is released from the water surface must be below a predetermined value.

Where are steam accumulators used?

Steam accumulators have been installed throughout modern industry including bio-technology, hospital and industrial sterilisation, product testing rigs, printing and food manufacturing, as well as more traditional industries such as breweries and dyehouses.

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).
