: What industries are steam accumulators used in the USA?
Reply: A steam accumulator is used in industry where sudden demands are frequent and the changes in the steam flow results in broad changes of the boiler pressure causing operating problems.
I knew a sugar refinery that was fireing bunker "c" and operating several turbines, when the load demand was a sudden increase in steam flow for the process there was lost of pressure at the turbine inlet, carry over to the superheater and lost of antomizing steam pressure at the burner. To resolve the problem a steam accumulator was installed that would handle the sudden changes reducing the effects by the larger reseved storage. A replacement of the use of accumulators to control the process operator from sucking the the pressure out of your boiler is a back pressure control valve, a lot simpler and lot less expensive than a steam accumulator.
