The steam tanks (otherwise known as steam accumulators) act as a buffer for steam storage, evening out the load on the boiler in processes where the steam demand shows characteristic peaks and troughs.
So steam accumulators can work well in applications where steam load is sporadic. Due to the fact that when steam boilers depressurise rapidly, they suffer from poor steam quality and the obstacle that is low-water shutdowns. To mitigate the issues caused by high steam demand, specifying engineers will either oversize the boiler or use a steam accumulator. The problem with oversizing is you will not bear the additional cost of an oversized boiler. The solution is to incorporate steam accumulation equipment into the steam system design.
Each steam tank is custom made to suit your specific needs, and is certified to British Standard.
