Steam Accumulator Steam Accumulator , a shell type pressure vessel that's used to store steam generated by a boiler and use it for varying load demands. Steam Boilers are usually designed for a certain capacity at that they could supply steam continuously that's also it's most continuous rating. So, the boiler designed for higher steam needs may be made to run on lower loads or lower steam demands however a boiler designed for lower loads cannot run on higher loads or higher steam demands. Generally, it's determined that the steam demand in a process isn't fixed and keeps changing with time. for a few periods of time, there might be lower load requirements than the boiler capacity while for a few amounts of your time there may be high load requirements. Low load requirements may be easily met by the boiler but high steam requirements cannot be met by this boiler as it isn't designed for such capacity. this is where a steam accumulator plays an import...
