|Economic steam generation is a requirement in today’s industry. Commonly, steam generators are over-designed to account for the peak process steam demand. This capital expenditure can be high if the peak demand is large in comparison to the average load. Occasionally, it is economical to design the steam generator for average steam demand and utilize a steam accumulator.
The Sterling Accumulator is designed to reduce the maximum boiler load while still meeting peak steam requirements. This is accomplished by operating the boiler at a constant rate and storing the generated steam in an accumulator until needed. Since steam is continually being charged to the accumulator, boiler load variation is diminished. Reduced load variation reduces moisture carryover into the steam system and increases generation efficiency. Operating at a near constant load also reduces the amount of maintenance required for all boiler components.
